Per-turn skill catalog delivery via `` messages. +//! +//! This module implements Claude Code's approach to making skills discoverable +//! by the LLM: on every request (via the `on_request` lifecycle hook), it +//! injects a lightweight catalog of available skills as a user-role +//! `` message.

This mirrors Claude Code's `sentSkillNames` cache +//! (`claude-code/src/utils/attachments.ts:2607-2635`). New skills discovered +//! mid-session (e.g. created via the `create-skill` workflow) are surfaced on +//! the next turn automatically because [`ForgeSkillFetch`] exposes +//! [`invalidate_cache`](crate::SkillFetchService::invalidate_cache). +//! - **Budget-aware formatting.** The catalog is capped at a small fraction of +//! the model's context window (default β‰ˆ 1%, mirroring +//! `claude-code/src/tools/SkillTool/prompt.ts:70-171`) so listing hundreds of +//! skills does not crowd out the user's own prompt. +//! - **Inert by default.** When the conversation has no context (pre-prompt +//! state) or no skills are available the handler does nothing and the +//! `ContextMessage` queue is left untouched β€” regressions are impossible for +//! agents that previously worked without this hook. + +use std::collections::{HashMap, HashSet}; +use std::sync::Arc; + +use async_trait::async_trait; +use forge_domain::{ + AgentId, ContextMessage, Conversation, ConversationId, EventData, EventHandle, + InvocableCommand, RequestPayload, +}; +use forge_template::Element; +use tokio::sync::Mutex; +use tracing::{debug, warn}; + +use crate::{InvocableCommandsProvider, SkillFetchService}; + +/// Default fraction of the context window reserved for the skill catalog. +/// +/// Matches Claude Code's `SKILL_LISTING_BUDGET_PCT = 0.01` from +/// `claude-code/src/tools/SkillTool/prompt.ts:72`. +pub const DEFAULT_BUDGET_FRACTION: f64 = 0.01; + +/// Fallback context window (in tokens) used when the caller cannot supply an +/// accurate value from model metadata. +/// +/// 200k approximates the smallest commonly available frontier context +/// window (Claude Sonnet 4, GPT-5) and keeps the budget conservative. +pub const DEFAULT_CONTEXT_TOKENS: u64 = 200_000; + +/// Rough character-to-token ratio used when converting between bytes and +/// tokens for budget accounting.

This helps you track progress, organize complex tasks, and demonstrate thoroughness to the user.\nIt also helps the user understand the progress of the task and overall progress of their requests.\n\n## How It Works\n\nEach call sends only the items that changed β€” you do not need to repeat the whole list.\n\nEach item has two required fields:\n- `content`: The task description. This is the **unique key** β€” the server matches on content to decide whether to add or update.\n- `status`: One of `pending`, `in_progress`, `completed`, or `cancelled`.\n\n**Rules:**\n- Item with this `content` does **not** exist yet β†’ **added** as a new task.\n- Item with this `content` already exists β†’ its `status` is **updated**.\n- `status: cancelled` β†’ the item is **removed** from the list entirely.\n- Items you do not mention are **left unchanged**.\n\nIDs are managed internally by the system and are never exposed to you.\n\n## When to Use This Tool\nUse this tool proactively in these scenarios:\n\n1. Complex multi-step tasks - When a task requires 3 or more distinct steps or actions\n2. Non-trivial and complex tasks - Tasks that require careful planning or multiple operations\n3. User explicitly requests todo list - When the user directly asks you to use the todo list\n4. User provides multiple tasks - When users provide a list of things to be done (numbered or comma-separated)\n5. After receiving new instructions - Immediately capture user requirements as todos\n6. When you start working on a task - Mark it as in_progress BEFORE beginning work. Ideally you should only have one todo as in_progress at a time\n7. After completing a task - Mark it as completed and add any new follow-up tasks discovered during implementation\n\n## When NOT to Use This Tool\n\nSkip using this tool when:\n1. There is only a single, straightforward task\n2. The task is trivial and tracking it provides no organizational benefit\n3. The task can be completed in less than 3 trivial steps\n4. The task is purely conversational or informational\n\nNOTE that you should not use this tool if there is only one trivial task to do. In this case you are better off just doing the task directly.\n\n## Examples of When to Use the Todo List\n\n\nUser: I want to add a dark mode toggle to the application settings. Make sure you run the tests and build when you're done!\nAssistant: I'll help add a dark mode toggle to your application settings. Let me create a todo list to track this implementation.\n*Creates todo list with the following items:*\n1. Creating dark mode toggle component in Settings page\n2. Adding dark mode state management (context/store)\n3. Implementing CSS-in-JS styles for dark theme\n4. Updating existing components to support theme switching\n5. Running tests and build process, addressing any failures or errors that occur\n*Begins working on the first task*\n\n\nThe assistant used the todo list because:\n1. Adding dark mode is a multi-step feature requiring UI, state management, and styling changes\n2. The user explicitly requested tests and build be run afterward\n3. The assistant inferred that tests and build need to pass by adding \"Ensure tests and build succeed\" as the final task\n\n\n\n\nUser: Help me rename the function getCwd to getCurrentWorkingDirectory across my project\nAssistant: Let me first search through your codebase to find all occurrences of 'getCwd'.\n*Uses grep or search tools to locate all instances of getCwd in the codebase*\nAssistant: I've found 15 instances of 'getCwd' across 8 different files. Let me create a todo list to track these changes.\n*Creates todo list with specific items for each file that needs updating*\n\n\nThe assistant used the todo list because:\n1. First, the assistant searched to understand the scope of the task\n2. Upon finding multiple occurrences across different files, it determined this was a complex task with multiple steps\n3. The todo list helps ensure every instance is tracked and updated systematically\n4. This approach prevents missing any occurrences and maintains code consistency\n\n\n\n\n\nUser: I need to implement these features for my e-commerce site: user registration, product catalog, shopping cart, and checkout flow.\nAssistant: I'll help implement these features. First, let's add all the features to the todo list.\n*Creates a todo list breaking down each feature into specific tasks based on the project architecture*\nAssistant: Let's start with user registration. This will involve creating database models, API endpoints, and frontend forms that integrate with your existing authentication system.\n\n\nThe assistant used the todo list because:\n1. The user provided multiple complex features to implement in a comma separated list\n2. The todo list helps organize these large features into manageable tasks\n3. This approach allows for tracking progress across the entire implementation\n\n\n\n\nUser: Can you help optimize my React application? It's rendering slowly and has performance issues.\nAssistant: I'll help optimize your React application. First, let me examine your codebase to identify potential performance bottlenecks.\n*Reviews component structure, render patterns, state management, and data fetching*\nAssistant: After analyzing your codebase, I've identified several performance issues. Let me create a todo list to track our optimization efforts.\n*Creates todo list with items like: 1) Implementing memoization for expensive calculations in ProductList, 2) Adding virtualization for long lists in Dashboard, 3) Optimizing image loading in Gallery component, 4) Fixing state update loops in ShoppingCart, 5) Reviewing bundle size and implementing code splitting*\nLet's start by implementing memoization for the expensive calculations in your ProductList component.\n\n\nThe assistant used the todo list because:\n1. First, the assistant examined the codebase to identify specific performance issues\n2. Based on this analysis, it identified multiple optimization opportunities\n3. Performance optimization is a non-trivial task requiring multiple steps\n4. The todo list helps methodically track improvements across different components\n5. This systematic approach ensures all performance bottlenecks are addressed\n\n\n\n## Examples of When NOT to Use the Todo List\n\n\nUser: How do I print 'Hello World' in Python?\nAssistant: In Python, you can print \"Hello World\" with this simple code:\n\npython\nprint(\"Hello World\")\n\nThis will output the text \"Hello World\" to the console when executed.\n\n\nThe assistant did not use the todo list because this is a single, trivial task that can be completed in one step. There's no need to track multiple tasks or steps for such a straightforward request.\n\n\n\n\nUser: What does the git status command do?\nAssistant: The git status command shows the current state of your working directory and staging area. It displays which changes have been staged, which haven't, and which files aren't being tracked by Git. This is a fundamental command for understanding the current state of your repository before making commits.\n\n\nThe assistant did not use the todo list because this is an informational request with no actual coding task to complete. The user is simply asking for an explanation, not for the assistant to perform multiple steps or tasks.\n\n\n\n\nUser: Can you add a comment to the calculateTotal function to explain what it does?\nAssistant: Sure, let me add a comment to the calculateTotal function to explain what it does.\n* Uses the patch tool to add a comment to the calculateTotal function *\n\n\nThe assistant did not use the todo list because this is a single, straightforward task confined to one location in the code. Adding a comment doesn't require tracking multiple steps or systematic organization.\n\n\n\n\nUser: Run npm install for me and tell me what happens.\nAssistant: I'll run the npm install command for you.\n\n*Executes: npm install*\n\nThe command completed successfully. Here's the output:\n[Output of npm install command]\n\nAll dependencies have been installed according to your package.json file.\n\n\nThe assistant did not use the todo list because this is a single command execution with immediate results. There are no multiple steps to track or organize, making the todo list unnecessary for this straightforward task.\n\n\n\n## Task States and Management\n\n1. **Task States**: Use these states to track progress:\n - `pending`: Task not yet started\n - `in_progress`: Currently working on (limit to ONE task at a time)\n - `completed`: Task finished successfully\n - `cancelled`: Task is no longer relevant β€” this removes it from the list\n\n2. **Task Management**:\n - Only send the items that changed β€” do not repeat unchanged items\n - Mark tasks `in_progress` BEFORE beginning work\n - Mark tasks `completed` IMMEDIATELY after finishing (don't batch completions)\n - Exactly ONE task must be `in_progress` at any time\n - Use `cancelled` to remove tasks that are no longer relevant\n - Complete current tasks before starting new ones\n\n3. **Task Completion Requirements**:\n - ONLY mark a task as `completed` when you have FULLY accomplished it\n - If you encounter errors, blockers, or cannot finish, keep the task as `in_progress`\n - When blocked, create a new task describing what needs to be resolved\n - Never mark a task as `completed` if:\n - Tests are failing\n - Implementation is partial\n - You encountered unresolved errors\n - You couldn't find necessary files or dependencies\n\n4. **Task Breakdown**:\n - Create specific, actionable items\n - Break complex tasks into smaller, manageable steps\n - Use clear, descriptive task names\n\nWhen in doubt, use this tool. Being proactive with task management demonstrates attentiveness and ensures you complete all requirements successfully.","arguments":{"todos":{"description":"List of todo items to create or update.

Each agent type has specific capabilities and tools available to it.\n\nAvailable agent types and the tools they have access to:\n{{#each agents}}\n- **{{id}}**{{#if description}}: {{description}}{{/if}}{{#if tools}}\n - Tools: {{#each tools}}{{this}}{{#unless @last}}, {{/unless}}{{/each}}{{/if}}\n{{/each}}\n\nWhen using the {{tool_names.task}} tool, you must specify a agent_id parameter to select which agent type to use.\n\nWhen NOT to use the {{tool_names.task}} tool:\n- If you want to read a specific file path, use the {{tool_names.read}} or {{tool_names.fs_search}} tool instead of the {{tool_names.task}} tool, to find the match more quickly\n- If you are searching for a specific class definition like \"class Foo\", use the {{tool_names.fs_search}} tool instead, to find the match more quickly\n- If you are searching for code within a specific file or set of 2-3 files, use the {{tool_names.read}} tool instead of the {{tool_names.task}} tool, to find the match more quickly\n- Other tasks that are not related to the agent descriptions above\n\n\nUsage notes:\n- Always include a short description (3-5 words) summarizing what the agent will do\n- Launch multiple agents concurrently whenever possible, to maximize performance; to do that, use a single message with multiple tool uses\n- When the agent is done, it will return a single message back to you. The result returned by the agent is not visible to the user. To show the user the result, you should send a text message back to the user with a concise summary of the result.\n- Agents can be resumed using the \\`session_id\\` parameter by passing the agent ID from a previous invocation. When resumed, the agent continues with its full previous context preserved. When NOT resuming, each invocation starts fresh and you should provide a detailed task description with all necessary context.\n- When the agent is done, it will return a single message back to you along with its agent ID. You can use this ID to resume the agent later if needed for follow-up work.\n- Provide clear, detailed prompts so the agent can work autonomously and return exactly the information you need.\n- Agents with \"access to current context\" can see the full conversation history before the tool call. When using these agents, you can write concise prompts that reference earlier context (e.g., \"investigate the error discussed above\") instead of repeating information. The agent will receive all prior messages and understand the context.\n- The agent's outputs should generally be trusted\n- Clearly tell the agent whether you expect it to write code or just to do research (search, file reads, web fetches, etc.), since it is not aware of the user's intent\n- If the agent description mentions that it should be used proactively, then you should try your best to use it without the user having to ask for it first. Use your judgement.\n- If the user specifies that they want you to run agents \"in parallel\", you MUST send a single message with multiple {{tool_names.task}} tool use content blocks. For example, if you need to launch both a build-validator agent and a test-runner agent in parallel, send a single message with both tool calls.\n\nExample usage:\n\n\n\"test-runner\": use this agent after you are done writing code to run tests\n\"greeting-responder\": use this agent when to respond to user greetings with a friendly joke\n\n\n\nuser: \"Please write a function that checks if a number is prime\"\nassistant: Sure let me write a function that checks if a number is prime\nassistant: First let me use the {{tool_names.write}} tool to write a function that checks if a number is prime\nassistant: I'm going to use the {{tool_names.write}} tool to write the following code:\n\nfunction isPrime(n) {\n if (n <= 1) return false\n for (let i = 2; i * i <= n; i++) {\n if (n % i === 0) return false\n }\n return true\n}\n\n\nSince a significant piece of code was written and the task was completed, now use the test-runner agent to run the tests\n\nassistant: Now let me use the test-runner agent to run the tests\nassistant: Uses the {{tool_names.task}} tool to launch the test-runner agent\n\n\n\nuser: \"Hello\"\n\nSince the user is greeting, use the greeting-responder agent to respond with a friendly joke\n\nassistant: \"I'm going to use the {{tool_names.task}} tool to launch the greeting-responder agent\"\n","arguments":{"agent_id":{"description":"The ID of the specialized agent to delegate to (e.g., \"sage\", \"forge\",\n\"muse\")","type":"string","is_required":true},"session_id":{"description":"Optional session ID to continue an existing agent session.

Configuration file watcher service. +//! +//! The [`ConfigWatcher`] watches Forge's configuration files and +//! directories (`~/.forge/config.toml`, installed plugins, hooks, +//! skills, …) for on-disk changes, debounces the raw filesystem events, +//! and hands the resulting [`ConfigChange`] values to a user-supplied +//! callback so the orchestrator can fire the +//! [`forge_domain::LifecycleEvent::ConfigChange`] plugin hook. +//! +//! # Wave C scope +//! +//! This module ships the real `notify-debouncer-full` event loop with: +//! +//! - a 1-second debounce window (matches Claude Code's +//! `awaitWriteFinish.stabilityThreshold: 1000`), +//! - 5-second internal-write suppression so Forge's own saves do not round-trip +//! through the hook system, +//! - a 1.7-second atomic-save grace period so a `unlink β†’ add` pair (Vim, +//! VSCode, etc.) fires one `Modify`-equivalent event instead of a spurious +//! delete followed by a create. +//! +//! Wiring the watcher into `ForgeAPI`/`ForgeServices` (and firing the +//! actual `ConfigChange` plugin hook) is handled by Wave C Part 2. +//! +//! # Design notes +//! +//! - **Internal write suppression.** Every time Forge itself writes a watched +//! config file it calls [`ConfigWatcher::mark_internal_write`] first. When +//! the filesystem notification finally arrives the debouncer callback +//! consults the `recent_internal_writes` map and skips the event if the +//! timestamp is still within the 5-second suppression window. This stops +//! Forge from firing its own `ConfigChange` hook for saves it made itself. +//! - **Debouncing.** Raw `notify` events are noisy β€” a single `Save` from a +//! text editor can produce half a dozen create/modify/rename events. +//! `notify-debouncer-full` coalesces them into a single event per file per +//! debounce tick. +//! - **Atomic saves.** Editors like Vim and VSCode save via a `unlink β†’ rename` +//! sequence. On `Remove` we stash the path in `pending_unlinks` and spawn a +//! short-lived `std::thread` that waits ~1.7 seconds and, if no `Create` has +//! consumed the entry in that window, fires a `Remove`-equivalent +//! `ConfigChange`. If a `Create` arrives first we remove the pending entry +//! and fire a single `Modify`-equivalent `ConfigChange` for the entire atomic +//! save. +//! - **Classification.** Plugin hooks filter on the wire string of +//! [`forge_domain::ConfigSource`] (e.g. `"user_settings"`, `"plugins"`), so +//! the watcher must know how to translate a raw absolute path back into a +//! source. [`ConfigWatcher::classify_path`] does that mapping based on +//!

The `UNIQUE(user_id, working_dir)` constraint on `workspaces` supports the idempotent "create or get" pattern that the client uses during sync. + +- [ ] 2.2. **Implement `Database` struct** wrapping `rusqlite::Connection`: + - `new(path) -> Result` β€” open/create DB, run migrations + - `create_api_key(user_id: Option<&str>) -> Result<(String, String)>` β€” returns `(user_id, key)` + - `validate_api_key(key: &str) -> Result>` β€” returns `user_id` if valid + - `create_workspace(user_id, working_dir, min_chunk, max_chunk) -> Result` + - `get_workspace_by_working_dir(user_id, working_dir) -> Result>` + - `upsert_file_ref(workspace_id, file_path, file_hash, node_id) -> Result<()>` + - `delete_file_refs(workspace_id, file_paths) -> Result` + - `list_file_refs(workspace_id) -> Result>` + + Use `tokio::task::spawn_blocking` for all SQLite calls since rusqlite is synchronous. + +### Phase 3: Ollama Embedding Client (`embedder.rs`) + +- [ ] 3.1. **Implement `Embedder` struct**: + - Stores `reqwest::Client`, `ollama_url`, `model_name`, `embedding_dim` + - `new(ollama_url, model, dim) -> Self` + - `embed_single(text: &str) -> Result>` β€” POST to `{ollama_url}/api/embed` with `{"model": model, "input": text}`, parse response `{"embeddings": [[f32; dim]]}`, return the first (and only) embedding vector + - `embed_batch(texts: &[String]) -> Result>>` β€” POST to `{ollama_url}/api/embed` with `{"model": model, "input": texts}`, parse all embeddings. Ollama's `/api/embed` endpoint supports batch input natively. + - `health_check() -> Result<()>` β€” GET `{ollama_url}/` to verify Ollama is running + + **Ollama API contract** (`POST /api/embed`): + ```json + Request: {"model": "nomic-embed-text", "input": ["text1", "text2"]} + Response: {"model": "nomic-embed-text", "embeddings": [[0.1, 0.2, ...], [0.3, 0.4, ...]]} + ``` + +### Phase 4: File Chunking (`chunker.rs`) + +- [ ] 4.1. **Implement line-aware chunker** β€” Split file content into chunks with line-number tracking: + - `chunk_file(path: &str, content: &str, min_size: u32, max_size: u32) -> Vec` + - `ChunkResult { path: String, content: String, start_line: u32, end_line: u32 }` + - Algorithm: + 1. Split content by lines + 2. Accumulate lines into a chunk until byte size exceeds `max_size` + 3. When a chunk is full, finalize it and start a new one + 4. If the last chunk is smaller than `min_size`, merge it with the previous chunk + 5. Track `start_line` (1-based) and `end_line` (inclusive) for each chunk + - Edge cases: empty files produce 0 chunks, files smaller than `min_size` produce 1 chunk + + **Rationale**: The client expects `FileChunk { path, content, start_line, end_line }` in search results. Line-based splitting preserves code structure better than byte-offset splitting. The `min_chunk_size` and `max_chunk_size` come from `WorkspaceDefinition` in the proto (or server defaults). + +### Phase 5: Qdrant Integration (`qdrant.rs`) + +- [ ] 5.1. **Implement `QdrantStore` struct**: + - Stores `qdrant_client::Qdrant` client and `embedding_dim` + - `new(qdrant_url, embedding_dim) -> Result` + +- [ ] 5.2. **Collection management**: + - `ensure_collection(workspace_id: &str) -> Result<()>` β€” create collection `ws_{workspace_id}` if not exists, with cosine distance and configured vector dimension + - `delete_collection(workspace_id: &str) -> Result<()>` β€” for workspace deletion + +- [ ] 5.3. **Upsert points (used by UploadFiles)**: + - `upsert_chunks(workspace_id: &str, chunks: Vec) -> Result>` where: + ``` + ChunkPoint { + id: String (UUID), + vector: Vec, + file_path: String, + content: String, + start_line: u32, + end_line: u32, + } + ``` + - Each point's payload: `{ "file_path": String, "content": String, "start_line": u32, "end_line": u32, "node_kind": "file_chunk" }` + - Returns the generated point UUIDs (used as `node_ids` in the response) + +- [ ] 5.4. **Delete by file path (used by DeleteFiles and re-upload)**: + - `delete_by_file_paths(workspace_id: &str, paths: &[String]) -> Result` β€” delete all points where `file_path` matches any of the given paths. Returns count of deleted points. + + **Critical**: When a file is re-uploaded (modified), the server must first delete all old chunks for that file path, then insert new chunks. This prevents stale chunks from accumulating. + +- [ ] 5.5. **Search (used by Search RPC)**: + - `search(workspace_id: &str, vector: Vec, limit: u32, filter: Option) -> Result>` + - `SearchHit { id: String, score: f32, file_path: String, content: String, start_line: u32, end_line: u32 }` + - Build Qdrant filter from `starts_with` (prefix match on `file_path`) and `ends_with` (suffix match on `file_path`) + - Use `SearchPoints` with `with_payload: true` + +- [ ] 5.6. **Scroll all points (used by ListFiles β€” optional optimization)**: + - Alternative: rely on SQLite `file_refs` table for `ListFiles` instead of scrolling Qdrant. This is faster and more reliable. + - Decision: **Use SQLite** for `ListFiles` since the client only needs `{path, hash}` pairs, not vector data. + +### Phase 6: Authentication Middleware (`auth.rs`) + +- [ ] 6.1. **Implement auth interceptor/extractor**: + - Extract `authorization` metadata from gRPC request + - Parse `Bearer ` format + - Look up token in SQLite `api_keys` table + - Return `user_id` on success, `tonic::Status::unauthenticated` on failure + - Skip auth for `CreateApiKey` (bootstrap method β€” the client calls it without auth, as seen in `context_engine.rs:121`) + + Implementation approach: use a helper function called from each RPC handler rather than a tonic interceptor, since `CreateApiKey` must be exempt. Signature: + ``` + async fn authenticate(db: &Database, request: &tonic::Request) -> Result + ``` + +### Phase 7: gRPC Service Implementation (`server.rs`) + +- [ ] 7.1. **Define `ForgeServiceImpl` struct**: + ```rust + pub struct ForgeServiceImpl { + db: Arc, + qdrant: Arc, + embedder: Arc, + config: Arc, + } + ``` + +- [ ] 7.2. **Implement `CreateApiKey`**: + - If `user_id` is provided, use it; otherwise generate UUID v4 + - Generate random API key (e.g., `uuid::Uuid::new_v4().to_string()` or a longer random string) + - Store `(key, user_id)` in SQLite + - Return `CreateApiKeyResponse { user_id: Some(UserId { id }), key }` + - No auth required on this method + +- [ ] 7.3. **Implement `CreateWorkspace`**: + - Authenticate request + - Extract `working_dir` from `WorkspaceDefinition` + - Check if workspace already exists for this `(user_id, working_dir)` β€” if yes, return existing + - Otherwise: generate UUID workspace_id, create Qdrant collection, insert into SQLite + - Return full `Workspace` message with `workspace_id`, `working_dir`, `created_at`, `node_count: 0`, etc. + + **Idempotency note**: The client calls `CreateWorkspace` on every sync. If a workspace already exists for the same `working_dir`, return the existing one (this is the pattern the production server uses, evidenced by the `UNIQUE(user_id, working_dir)` constraint and the client's `find_workspace_by_path` fallback in `context_engine_service.rs`). + +- [ ] 7.4. **Implement `UploadFiles`**: + - Authenticate request + - Extract `workspace_id` and `files` from request + - For each file in `content.files`: + 1. Compute SHA-256 hash of `file.content` (must match client's `compute_hash`) + 2. Delete existing chunks for this `file.path` in Qdrant (handles re-uploads) + 3. Split `file.content` into chunks using `chunker::chunk_file` + 4. Embed all chunks via `embedder.embed_batch` + 5. Upsert chunk vectors + payloads into Qdrant + 6. Upsert `file_refs` entry in SQLite with `(workspace_id, file.path, sha256_hash, node_id)` + - Return `UploadResult { node_ids: [all chunk UUIDs], relations: [] }` + + **Concurrency**: The client sends files in parallel (`buffer_unordered`). The server must handle concurrent `UploadFiles` calls safely. SQLite operations are serialized naturally (single writer), and Qdrant handles concurrent writes. No explicit locking needed beyond what rusqlite provides. + +- [ ] 7.5. **Implement `ListFiles`**: + - Authenticate request + - Query SQLite `file_refs` table for all entries matching `workspace_id` + - Map each row to `FileRefNode { node_id, hash, git: None, data: FileRef { path, file_hash } }` + - Return `ListFilesResponse { files }` + +- [ ] 7.6. **Implement `DeleteFiles`**: + - Authenticate request + - Extract `workspace_id` and `file_paths` + - Delete Qdrant points by `file_path` filter for each path + - Delete SQLite `file_refs` entries + - Return `DeleteFilesResponse { deleted_nodes: count, deleted_relations: 0 }` + +- [ ] 7.7. **Implement `Search`**: + - Authenticate request + - Extract `workspace_id`, `query.prompt`, `query.top_k` (default 10), `query.limit` + - Embed `query.prompt` via `embedder.embed_single` + - Build Qdrant filter from `query.starts_with` (file path prefix) and `query.ends_with` (file extension suffix) + - Execute ANN search in Qdrant collection `ws_{workspace_id}` + - Map results to `QueryItem` with: + - `node.data = FileChunk { path, content, start_line, end_line }` + - `node.node_id = point UUID` + - `node.workspace_id = workspace_id` + - `node.hash = ""` (not used for chunks) + - `distance = Some(1.0 - score)` (Qdrant cosine returns similarity 0..1, client expects distance) + - `relevance = Some(score)` + - **Reranking with `relevance_query`**: For MVP, use the same embedding score as relevance. Reranking with a cross-encoder model can be added later as an enhancement. + - Apply `limit` to cap the number of returned results + - Return `SearchResponse { result: QueryResult { data: items } }` + +- [ ] 7.8. **Implement `HealthCheck`**: + - Return `HealthCheckResponse { status: "ok".to_string() }` + - Optionally verify Qdrant and Ollama connectivity + +- [ ] 7.9. **Stub remaining methods** β€” Return `tonic::Status::unimplemented("Not supported")` for: `GetWorkspaceInfo`, `ListWorkspaces`, `DeleteWorkspace`, `ChunkFiles`, `ValidateFiles`, `SelectSkill`, `FuzzySearch` + +### Phase 8: Testing & Integration + +- [ ] 8.1. **Unit tests for `chunker.rs`**: + - Empty file β†’ 0 chunks + - Small file (< min_size) β†’ 1 chunk + - Large file β†’ multiple chunks with correct line numbers + - Line boundaries are respected (no mid-line splits) + +- [ ] 8.2. **Unit tests for `auth.rs`**: + - Valid token returns user_id + - Missing header returns unauthenticated + - Invalid token returns unauthenticated + +- [ ] 8.3. **Integration test: full sync cycle**: + - Call `CreateApiKey` β†’ get token + - Call `CreateWorkspace` β†’ get workspace_id + - Call `UploadFiles` with test files + - Call `ListFiles` β†’ verify file hashes match SHA-256 of uploaded content + - Call `Search` β†’ verify results contain uploaded content + - Call `DeleteFiles` β†’ verify files removed + - Call `ListFiles` β†’ verify empty + +- [ ] 8.4. **Hash compatibility test**: + - Verify that the server's SHA-256 hash output matches the Forge client's `compute_hash` function (hex-encoded SHA-256 of raw content string). Use the same test vectors: + ``` + compute_hash("old content") == sha256_hex("old content") + compute_hash("new content") == sha256_hex("new content") + ``` + +### Phase 9: Docker & Deployment + +- [ ] 9.1. **Create `docker-compose.yml`** with three services: + ```yaml + services: + workspace-server: + build: . + ports: ["50051:50051"] + environment: + QDRANT_URL: http://qdrant:6334 + OLLAMA_URL: http://ollama:11434 + depends_on: [qdrant, ollama] + + qdrant: + image: qdrant/qdrant:latest + ports: ["6333:6333", "6334:6334"] + volumes: ["qdrant_data:/qdrant/storage"] + + ollama: + image: ollama/ollama:latest + ports: ["11434:11434"] + volumes: ["ollama_data:/root/.ollama"] + ``` + +- [ ] 9.2. **Create `Dockerfile`** β€” multi-stage build: + - Stage 1: Build with `rust:1.79-bookworm` + `protobuf-compiler` + - Stage 2: Runtime with `debian:bookworm-slim` + +- [ ] 9.3. **Create startup script** that pulls `nomic-embed-text` model on first Ollama boot: + ```bash + ollama pull nomic-embed-text + ``` + +--- + +## Verification Criteria + +1. **Forge CLI connects successfully** β€” `FORGE_WORKSPACE_SERVER_URL=http://localhost:50051` allows forge to complete `:sync` and `:workspace-init` without errors +2. **Incremental sync works** β€” second `:sync` call only uploads changed files (verified by `ListFiles` hash comparison) +3. **Semantic search returns relevant results** β€” `sem_search` tool returns `FileChunk` nodes with correct `file_path`, `content`, `start_line`, `end_line` +4. **Hash compatibility** β€” `ListFiles` returns hashes identical to what the Forge client computes locally via `sha2::Sha256` +5. **Concurrent uploads** β€” server handles parallel `UploadFiles` calls without data corruption +6. **Fully offline** β€” no external network calls (Qdrant and Ollama run locally) + +--- + +## Potential Risks and Mitigations + +1. **Qdrant collection naming collisions** + Collections named `ws_{uuid}` are globally unique per workspace. Risk is negligible since workspace IDs are UUID v4. + Mitigation: None needed. + +2. **Ollama embedding latency during large syncs** + `nomic-embed-text` is fast (~1ms per embedding on CPU) but a large codebase (10k+ files) will generate many chunks. + Mitigation: Batch embedding calls (Ollama `/api/embed` supports arrays). Process files sequentially but chunks within a file in batch. The client already serializes uploads per-file, so server-side batching within a single `UploadFiles` call is sufficient. + +3. **SQLite write contention under concurrent uploads** + Concurrent `UploadFiles` calls all write to `file_refs` table. + Mitigation: Use `rusqlite` with WAL mode (`PRAGMA journal_mode=WAL`) which allows concurrent reads and serialized writes without blocking. Wrap `Connection` in `Arc>` for thread safety. + +4. **File re-upload leaves stale chunks in Qdrant** + If a file is modified and re-uploaded, old chunks must be deleted first. + Mitigation: Step 7.4 explicitly deletes all existing chunks for a file path before inserting new ones. This is done within the same `UploadFiles` handler. + +5. **Proto compatibility drift** + If the upstream `forge.proto` changes, the server must be updated. + Mitigation: Pin to a specific proto version. The proto is stable (all MVP methods already exist and the client's usage patterns are well-understood from `context_engine.rs`). + +6. **No reranking in MVP** + The production server likely uses a cross-encoder for reranking (the `relevance_query` field). The MVP uses raw embedding similarity as relevance. + Mitigation: Acceptable for MVP. Results will be less precise but functional. A reranking pass with a local model (e.g., `BAAI/bge-reranker-base` via Ollama or a small ONNX model) can be added in a follow-up. + +7. **Embedding model dimension mismatch** + If someone uses a different Ollama model, the vector dimension won't be 768. + Mitigation: Make `embedding_dim` configurable. Validate dimension on first embedding call and fail fast with a clear error. + +--- + +## Alternative Approaches + +1. **In-memory metadata instead of SQLite**: Store api_keys and workspaces in `HashMap` behind `Arc>`. Simpler but data is lost on restart, requiring full re-sync every time the server restarts. **Not recommended** for any real usage. + +2. **PostgreSQL + pgvector instead of Qdrant**: Single database for both metadata and vectors.

Add `marketplace.json` deserialization type to `forge_domain`** + + **File:** `crates/forge_domain/src/plugin.rs` + + Add a new struct `MarketplaceManifest` with the shape: + ``` + { "plugins": [{ "name": "...", "source": "./plugin", ... }] } + ``` + The key field is `source` (relative path from the marketplace.json to the real plugin root). Use `#[serde(rename_all = "camelCase")]` for Claude Code wire compat. The `plugins` field is a `Vec` where each entry has at minimum `name: Option` and `source: String`. + + **Rationale:** Forge needs a way to parse this indirection file to resolve the actual plugin root within marketplace directories. + +- [x] **Task 1.2. Add marketplace-aware scanning to `scan_root`** + + **File:** `crates/forge_repo/src/plugin.rs` (function `scan_root` at lines 161-212) + + Currently `scan_root` iterates immediate child directories and calls `load_one_plugin` on each. The change: + - After `load_one_plugin` returns `Ok(None)` (no manifest found), check for `/.claude-plugin/marketplace.json` or `/marketplace.json`. + - If found, parse it as `MarketplaceManifest`. + - For each entry in `plugins`, resolve `/` as a new plugin directory and call `load_one_plugin` on it. + - This adds a second scan level specifically for marketplace indirection without general recursive descent. + + **Rationale:** Claude Code stores marketplace plugins at `~/.claude/plugins/marketplaces//` with `marketplace.json` pointing to nested plugin directories. Without this, marketplace plugins are invisible to Forge. + +- [x] **Task 1.3. Handle `cache/` versioned directory layout** + + **File:** `crates/forge_repo/src/plugin.rs` + + Claude Code also uses `~/.claude/plugins/cache////` layout. The `hooks.json` in claude-mem references this path pattern.

Forge should discover both layouts. + +- [x] **Task 1.4. Add test fixture for marketplace plugin structure** + + **Files:** + - `crates/forge_repo/src/fixtures/plugins/marketplace_plugin/` (new directory) + - Or `crates/forge_services/tests/fixtures/plugins/marketplace-provider/` + + Create a minimal fixture replicating the marketplace layout: + ``` + marketplace-provider/ + β”œβ”€β”€ .claude-plugin/ + β”‚ β”œβ”€β”€ plugin.json (repo-level manifest) + β”‚ └── marketplace.json (source: "./plugin") + β”œβ”€β”€ plugin/ + β”‚ β”œβ”€β”€ .claude-plugin/plugin.json + β”‚ β”œβ”€β”€ .mcp.json + β”‚ β”œβ”€β”€ hooks/hooks.json + β”‚ β”œβ”€β”€ skills/demo-skill/SKILL.md + β”‚ └── commands/demo-cmd.md + ``` + + Add tests in `crates/forge_repo/src/plugin.rs` (inline test module) verifying: + - `scan_root` discovers the nested plugin (not the repo root). + - Component paths (skills, commands) resolve correctly. + - MCP servers from the nested `.mcp.json` are picked up. + - The repo-root `.claude-plugin/plugin.json` is NOT loaded as a separate plugin. + + **Rationale:** Without fixture tests, regressions in marketplace discovery will go undetected. + +### Phase 2: Install-Time Marketplace Awareness + +This phase makes `forge plugin install ` correctly handle marketplace directories by locating the real plugin root and counting its components. + +- [x] **Task 2.1. Detect marketplace indirection during install** + + **File:** `crates/forge_main/src/ui.rs` (function `on_plugin_install` at lines 4791-4930) + + After finding and parsing the manifest (step 2, lines 4804-4824), add marketplace resolution: + - Check for a sibling `marketplace.json` next to the found `plugin.json`. + - If present, parse it as `MarketplaceManifest`. + - If there's exactly one plugin entry with a `source` field, resolve `/` as the effective plugin root. + - Re-locate and re-parse the manifest from the effective root. + - Use the effective root for component counting (step 4) and file copying (step 5). + + **Rationale:** When a user runs `forge plugin install /path/to/marketplace/author`, we should install the actual plugin (e.g., `./plugin/`), not the entire marketplace repo. + +- [x] **Task 2.2.

Copy only the effective plugin root (not the entire marketplace repo)** + + **File:** `crates/forge_main/src/ui.rs` (step 5, lines 4900-4915) + + When marketplace indirection was detected in Task 2.1, `copy_dir_recursive` should copy from the effective plugin root (e.g., `/plugin/`) to the target, not from the original `` (the entire marketplace repo with `src/`, `tests/`, `node_modules/`, etc.). + + **Rationale:** Copying the entire marketplace repo wastes disk space and includes dev files, tests, and other non-plugin content. Claude Code's own installer only copies the plugin subdirectory. + +- [x] **Task 2.4. Add install-time tests for marketplace plugins** + + **File:** `crates/forge_main/src/ui.rs` or a new integration test file + + Test that: + - `find_install_manifest` + marketplace detection resolves to the nested plugin. + - Component counts reflect the nested plugin's actual content. + - `copy_dir_recursive` copies from the effective root. + + **Rationale:** Ensures the install flow works end-to-end for marketplace-structured plugins. + +### Phase 3: `CLAUDE_PLUGIN_ROOT` Environment Variable Alias + +This phase ensures Claude Code plugin hooks and MCP servers that reference `${CLAUDE_PLUGIN_ROOT}` work under Forge without any plugin-side modifications. + +- [x] **Task 3.1. Add `CLAUDE_PLUGIN_ROOT` alias for hook subprocesses** + + **File:** `crates/forge_app/src/hooks/plugin.rs` (around lines 269-272) + + After inserting `FORGE_PLUGIN_ROOT`, also insert `CLAUDE_PLUGIN_ROOT` with the same value: + ```rust + if let Some(ref root) = source.plugin_root { + let root_str = root.display().to_string(); + env_vars.insert(FORGE_PLUGIN_ROOT.to_string(), root_str.clone()); + env_vars.insert("CLAUDE_PLUGIN_ROOT".to_string(), root_str); + } + ``` + + Also add the constant `const CLAUDE_PLUGIN_ROOT: &str = "CLAUDE_PLUGIN_ROOT";` alongside the existing constants (line 46). + + **Rationale:** Claude Code plugins universally use `${CLAUDE_PLUGIN_ROOT}` in hook commands. The `substitute_variables` function (`crates/forge_services/src/hook_runtime/shell.rs:483-516`) replaces `${VAR}` from the env_vars map, and the shell itself expands `$CLAUDE_PLUGIN_ROOT`. Both paths require the variable to be present in the env map. + +- [x] **Task 3.2. Add `CLAUDE_PLUGIN_ROOT` alias for MCP server subprocesses** + + **File:** `crates/forge_services/src/mcp/manager.rs` (around line 117) + + After injecting `FORGE_PLUGIN_ROOT` into stdio server env, also inject `CLAUDE_PLUGIN_ROOT`: + ```rust + stdio.env + .entry(FORGE_PLUGIN_ROOT_ENV.to_string()) + .or_insert_with(|| plugin_root.clone()); + stdio.env + .entry("CLAUDE_PLUGIN_ROOT".to_string()) + .or_insert_with(|| plugin_root.clone()); + ``` + + **Rationale:** MCP server commands from Claude Code plugins also reference `${CLAUDE_PLUGIN_ROOT}` (e.g., `"command": "${CLAUDE_PLUGIN_ROOT}/scripts/mcp-server.cjs"`). The same variable needs to be available in the MCP subprocess environment. + +- [x] **Task 3.3. Update reference env builder and tests** + + **Files:** + - `crates/forge_services/src/hook_runtime/env.rs` (reference `build_hook_env_vars` function) + - `crates/forge_app/src/hooks/plugin.rs` (existing tests) + - `crates/forge_services/src/mcp/manager.rs` (existing tests) + + Update the reference builder to also produce `CLAUDE_PLUGIN_ROOT` when `plugin_root` is provided. Update all existing tests that assert on env var maps to expect the new alias. Add a specific test verifying that `${CLAUDE_PLUGIN_ROOT}` in a command string is correctly substituted. + + **Rationale:** Test coverage ensures the alias doesn't regress and that both `${FORGE_PLUGIN_ROOT}` and `${CLAUDE_PLUGIN_ROOT}` work in command strings. + +### Phase 4: `CLAUDE_PROJECT_DIR` and `CLAUDE_SESSION_ID` Aliases + +Similar to Phase 3, Claude Code hooks may also reference `CLAUDE_PROJECT_DIR` and other `CLAUDE_*` prefixed variables. + +- [x] **Task 4.1. Add remaining `CLAUDE_*` env var aliases for hooks** + + **File:** `crates/forge_app/src/hooks/plugin.rs` (env var construction block, lines 262-307) + + Add aliases: + - `CLAUDE_PROJECT_DIR` β†’ same as `FORGE_PROJECT_DIR` + - `CLAUDE_SESSION_ID` β†’ same as `FORGE_SESSION_ID` + + Only add these when the hook source is a `ClaudeCode` plugin (check `source.source == PluginSource::ClaudeCode`) to avoid polluting the env for Forge-native plugins. + + **Rationale:** Some Claude Code hooks reference `$CLAUDE_PROJECT_DIR`. Conditional injection based on plugin source avoids adding unnecessary variables for Forge-native plugins. + +- [x] **Task 4.2. Add `CLAUDE_PROJECT_DIR` alias for MCP subprocesses** + + **File:** `crates/forge_services/src/mcp/manager.rs` + + Alongside `FORGE_PROJECT_DIR`, also inject `CLAUDE_PROJECT_DIR` with the same value for plugin-contributed MCP servers. + + **Rationale:** MCP server scripts may use `$CLAUDE_PROJECT_DIR` in their runtime logic. + +- [x] **Task 4.3. Update tests for all aliases** + + **Files:** Same as Task 3.3 plus any new tests needed for `CLAUDE_PROJECT_DIR` / `CLAUDE_SESSION_ID`. + + **Rationale:** Ensures complete test coverage for all Claude Code env var aliases. + +### Phase 5: Trust Prompt Modes Component Display (Optional Enhancement) + +Claude Code plugins may include `modes/` directories with custom operational modes. This is a lower-priority enhancement for display completeness. + +- [x] **Task 5.1. Add `modes` count to trust prompt COMPONENTS section** + + **File:** `crates/forge_main/src/ui.rs` (trust prompt section, around line 4878) + + Add a line: + ```rust + let modes_count = count_entries(&source, "modes"); + ``` + And display it in the COMPONENTS section if > 0. + + **Rationale:** Gives users visibility into plugin modes during the trust prompt. Modes are informational only β€” Forge doesn't execute them β€” but seeing "Modes: 36" helps users understand what the plugin contains. + +- [x] **Task 5.2. Add `modes` count to `/plugin info` and `/plugin list`** + + **Files:** `crates/forge_main/src/ui.rs` (functions `on_plugin_info` at line 4691, `format_plugin_components` at line 131) + + Add modes count alongside existing component counts. + + **Rationale:** Consistency between install prompt and info/list views. + +## Verification Criteria + +- `forge plugin install /path/to/marketplace/author` correctly resolves `marketplace.json` β†’ installs only the `./plugin` subdirectory +- Trust prompt shows correct component counts: skills (7), commands (0), agents (0), hooks (present), MCP servers (1) for the claude-mem example +- Runtime `scan_root` of `~/.claude/plugins/` discovers plugins inside `marketplaces//` via `marketplace.json` indirection +- Hooks using `${CLAUDE_PLUGIN_ROOT}` in their commands execute correctly with the variable resolved to the plugin's directory path +- MCP servers with `${CLAUDE_PLUGIN_ROOT}` in their command field start correctly +- Existing Forge-native plugins and Claude Code flat-layout plugins continue to work without regression +- All existing plugin tests pass, plus new tests for marketplace layout and env var aliases +- `cargo check` and `cargo insta test --accept` pass + +## Potential Risks and Mitigations + +1. **Ambiguous manifests β€” repo-root vs nested plugin both have `.claude-plugin/plugin.json`** + Mitigation: When marketplace.json is detected, the repo-root manifest is used only for metadata display; the nested plugin's manifest becomes the source of truth for component resolution. `scan_root` should only emit one `LoadedPlugin` per marketplace entry, not one for the repo root AND one for the nested plugin. + +2. **Multiple plugins per marketplace β€” `marketplace.json` may list more than one plugin** + Mitigation: Iterate all entries in `plugins[]`, resolving each `source` independently. Each becomes a separate `LoadedPlugin`. The install flow can prompt the user to select which plugin to install if there are multiple. + +3. **Broken `source` paths β€” `marketplace.json` may point to non-existent directories** + Mitigation: Validate that `/` exists and contains a manifest; surface a clear error if not. + +4. **Performance β€” extra filesystem probes for marketplace.json on every scan** + Mitigation: The extra `exists()` call per child directory is negligible compared to existing manifest probing (already 3 candidates per dir). Marketplace.json is only probed when no manifest is found directly. + +5. **Env var pollution β€” adding `CLAUDE_*` aliases unconditionally** + Mitigation: Phase 4 conditionally injects `CLAUDE_*` aliases only for `PluginSource::ClaudeCode` plugins. Phase 3 (`CLAUDE_PLUGIN_ROOT`) is added unconditionally as it's the most critical variable and the cost is negligible. + +## Alternative Approaches + +1. **Symlink-based resolution**: Instead of parsing `marketplace.json`, detect symlinks at `~/.claude/plugins/` that point into deeper directories. Rejected because Claude Code uses actual directory nesting, not symlinks. + +2. **Recursive scan to arbitrary depth**: Make `scan_root` recurse until it finds manifests at any depth. Rejected because it's expensive and fragile β€” could accidentally discover manifests in `node_modules/` or test fixtures. + +3. **Require users to point at the nested plugin directory**: Tell users to run `forge plugin install /path/to/author/plugin/` instead of the repo root. Rejected because it creates a poor UX and diverges from how Claude Code installs marketplace plugins. + +4. **Transform Claude Code hooks into Forge format at install time**: Rewrite `${CLAUDE_PLUGIN_ROOT}` β†’ `${FORGE_PLUGIN_ROOT}` in hooks.json during install. Rejected because it's fragile, breaks updates, and the original hooks.json should remain unmodified for Claude Code compatibility. diff --git a/plans/2026-04-11-forge-architectural-refactoring-v1.md b/plans/2026-04-11-forge-architectural-refactoring-v1.md new file mode 100644 index 0000000000..89ce0f68b0 --- /dev/null +++ b/plans/2026-04-11-forge-architectural-refactoring-v1.md @@ -0,0 +1,343 @@ +# Forge Architectural Refactoring Plan + +## Objective + +Transform the Forge codebase from its current architecture β€” characterized by god objects, massive delegation boilerplate, blurred layer boundaries, and inconsistent trait placement β€” into a clean, modular architecture with strict layer separation, minimal boilerplate, explicit dependency graphs, and clear ownership boundaries for every type and trait. + +**Non-goals:** This plan does not change external behavior, public CLI interfaces, or the server protocol.

Alternatively, keep the concrete types but re-export them from `forge_port` with clear documentation that these are chosen wire types. + +- [ ] 1.6 Update all downstream crates (`forge_app`, `forge_services`, `forge_infra`, `forge_repo`) to import traits from `forge_port` instead of `forge_domain::repo` or `forge_app::infra`. + +- [ ] 1.7 In `forge_domain`, remove `repo.rs`, `console.rs`, and all re-exports of moved traits. `forge_domain/src/lib.rs` will no longer contain any trait with async methods or I/O semantics. + +### Verification + +- `cargo check --workspace` passes with no errors +- All traits previously accessible via `forge_domain::*` or `forge_app::*` are now accessible via `forge_port::*` +- `forge_domain` has zero `async_trait` dependency (domain layer becomes purely synchronous types) +- No grep match for `use forge_domain::.*Repository` or `use forge_app::.*Infra` outside `forge_port` + +--- + +## Phase 2: Decompose the God `Services` Trait into Focused Capability Groups + +**Rationale:** The `Services` trait (`crates/forge_app/src/services.rs:735-814`) has 30 associated types and 30 accessor methods. This forces every consumer to carry the entire universe of services even when it needs only one. The ~575 lines of blanket delegation (`crates/forge_app/src/services.rs:816-1390`) exist solely to flatten `services.conversation_service().find_conversation(id)` into `services.find_conversation(id)` β€” syntactic sugar at enormous boilerplate cost. + +### Implementation + +- [ ] 2.1 Define **focused capability group traits**, each containing only closely-related service accessors. Candidate grouping: + + | Group Trait | Contains | Used By | + |---|---|---| + | `FileServices` | `FsReadService`, `FsWriteService`, `FsPatchService`, `FsRemoveService`, `FsSearchService`, `FsUndoService`, `ImageReadService`, `PlanCreateService` | Tool executor, orch | + | `ConversationServices` | `ConversationService`, `TemplateService`, `AttachmentService` | Orch, compact | + | `ProviderServices` | `ProviderService`, `ProviderAuthService`, `AppConfigService` | Orch, agent resolver | + | `DiscoveryServices` | `FileDiscoveryService`, `CustomInstructionsService`, `WorkspaceService` | System prompt, tool executor | + | `McpServices` | `McpService`, `McpConfigManager` | Tool executor, orch | + | `AgentServices` | `AgentRegistry`, `CommandLoaderService`, `SkillFetchService`, `PluginLoader` | Orch, tool resolver | + | `PolicyServices` | `PolicyService`, `FollowUpService`, `AuthService` | Tool executor, orch | + | `HookServices` | `HookConfigLoader`, `HookExecutor`, `ElicitationDispatcher` | Lifecycle fires, orch | + | `ShellServices` | `ShellService`, `NetFetchService` | Tool executor | + +- [ ] 2.2 Each group trait follows the same pattern as current `Services` but with 2-8 associated types instead of 30. Each has accessor methods only. + +- [ ] 2.3 Define a `Services` supertrait as the union: `trait Services: FileServices + ConversationServices + ProviderServices + DiscoveryServices + McpServices + AgentServices + PolicyServices + HookServices + ShellServices + EnvironmentInfra + Send + Sync + Clone + 'static {}` with a blanket impl `impl Services for T where T: FileServices + ... {}`. + +- [ ] 2.4 **Delete all blanket delegation impls** (`crates/forge_app/src/services.rs:816-1390`). Consumers that need `ConversationService` methods use `services.conversation_service().find_conversation(id)` directly. This is explicit, has zero boilerplate, and makes dependency tracking trivial. + +- [ ] 2.5 Update every consumer in `forge_app` (orchestrator, tool_executor, system_prompt, hooks, etc.) to bound on the **minimal group trait(s)** they actually need. Example: `tool_executor` bounds on `FileServices + ShellServices + McpServices + PolicyServices` instead of the full `Services`. + +- [ ] 2.6 Update `ForgeServices` implementation: instead of one `impl Services for ForgeServices` block with 30 type aliases and 30 methods, implement each group trait separately. The bounds on each `impl` block will be smaller β€” only the infra traits actually needed by the services in that group. + +### Verification + +- No single trait in `forge_app` has more than 10 associated types +- `cargo check --workspace` passes +- The `services.rs` file is under 400 lines (from current 1390) +- Every consumer's trait bounds are documented in its function/struct signature β€” readable at a glance + +--- + +## Phase 3: Eliminate the Triple-Layer Delegation Chain (ForgeInfra / ForgeRepo / ForgeServices) + +**Rationale:** Currently the architecture has a single generic `F` parameter threaded through `ForgeServices>`. Both `ForgeRepo` and `ForgeInfra` must implement **every** port trait (even those they don't own) via pure delegation to `self.infra`, producing ~500 lines of boilerplate in `ForgeRepo` (`crates/forge_repo/src/forge_repo.rs:226-699`) and ~280 lines in `ForgeInfra` (`crates/forge_infra/src/forge_infra.rs:142-412`). This happens because `ForgeServices` requires `F: AllTraits` as a single composite parameter. + +### Implementation + +- [ ] 3.1 **Split `ForgeServices` into two type parameters**: `ForgeServices` where `I: InfraPort` (file ops, HTTP, commands, walker, grpc, environment, console) and `R: RepoPort` (conversations, snapshots, providers, chat, workspace index, skills, plugins, validation, fuzzy search, KV store). Each parameter requires only its own subset of traits. + +- [ ] 3.2 **Remove all passthrough delegation from `ForgeRepo`**: `ForgeRepo` will no longer implement `FileReaderInfra`, `HttpInfra`, `CommandInfra`, `WalkerInfra`, etc. These impls (`crates/forge_repo/src/forge_repo.rs:278-699`) β€” ~420 lines β€” are deleted entirely. `ForgeRepo` only implements repository traits (`SnapshotRepository`, `ConversationRepository`, `ChatRepository`, `ProviderRepository`, etc.) that it actually owns. + +- [ ] 3.3 **Remove all passthrough delegation from `ForgeInfra`'s aggregator**: `ForgeInfra` struct still holds inner services (`ForgeFileReadService`, `ForgeFileWriteService`, etc.) and implements infra traits by delegating to them. This delegation is kept because it provides the real concrete implementation. However, review and consolidate traits where possible (e.g., merge `FileInfoInfra` + `FileReaderInfra` + `FileWriterInfra` + `FileRemoverInfra` + `FileDirectoryInfra` into a single `FileSystemPort`). + +- [ ] 3.4 Refactor concrete service types in `forge_services` to take the specific ports they need. For example, `ForgeFsWrite` should take `Arc` (or a trait alias) instead of `Arc` where `F: 25-trait-bound`. Services that need both infra and repo take `(Arc, Arc)`. + +- [ ] 3.5 In `ForgeAPI::init`, wire `ForgeServices::new(Arc, Arc>)` with two parameters instead of nesting `ForgeRepo` and passing the whole stack. + +- [ ] 3.6 **Consolidate EnvironmentInfra delegation**: Currently `EnvironmentInfra` is implemented at 4 levels (ForgeInfra, ForgeRepo, ForgeServices, and via blanket `Services`). With the split, only `ForgeInfra` implements `EnvironmentInfra`. Services that need it depend on `I: EnvironmentInfra` directly. + +### Verification + +- `ForgeRepo` is under 300 lines (from 699) +- No trait is implemented by `ForgeRepo` that purely delegates to `self.infra` +- `ForgeServices` struct definition has at most 2 type parameters +- `ConsoleWriter` is implemented only once (in `ForgeInfra`) and passed via the infra parameter +- The total line count of `forge_repo/src/forge_repo.rs` + `forge_infra/src/forge_infra.rs` is < 600 (from ~1111) + +--- + +## Phase 4: Extract Provider DTO Layer from `forge_app` into `forge_repo` + +**Rationale:** `crates/forge_app/src/dto/` contains ~135 public types: OpenAI, Anthropic, and Google wire-format request/response DTOs with ~40 transformer implementations. These are infrastructure adapter types used exclusively by provider implementations in `forge_repo`. They have no business in the application layer. Currently `forge_repo` depends on `forge_app` partly because of these DTOs β€” the dependency arrow is backwards. + +### Implementation + +- [ ] 4.1 Move the entire `crates/forge_app/src/dto/` directory (except `tools_overview.rs`) into `crates/forge_repo/src/dto/`. This includes: + - `dto/openai/` (request, response, error, model, reasoning, tool_choice, transformers/*) + - `dto/anthropic/` (request, response, error, transforms/*) + - `dto/google/` (request, response) + +- [ ] 4.2 Keep `tools_overview.rs` in `forge_app` since it's an application-level aggregate type not tied to any specific provider. + +- [ ] 4.3 Update `forge_repo/Cargo.toml` to include any DTO dependencies currently pulled through `forge_app` (likely already present as `forge_repo` handles provider logic). + +- [ ] 4.4 Remove the `pub mod dto;` export from `forge_app/src/lib.rs` (except `tools_overview`). Update `forge_api/src/lib.rs` to stop re-exporting `forge_app::dto::*`. + +- [ ] 4.5 Verify that `forge_repo` no longer depends on `forge_app` for DTO types. Audit remaining `forge_repo -> forge_app` dependency edges β€” if the only remaining reason is port traits, those now come from `forge_port` (Phase 1), potentially making the `forge_repo -> forge_app` dependency eliminable. + +### Verification + +- `forge_app` has zero files under `src/dto/openai/`, `src/dto/anthropic/`, `src/dto/google/` +- `forge_repo` contains all provider DTO files +- No `use forge_app::dto::` import in `forge_repo` or `forge_infra` +- If `forge_repo -> forge_app` dependency can be eliminated entirely, validate the dependency graph: `forge_services -> forge_app`, `forge_services -> forge_repo`, `forge_services -> forge_port`; but `forge_repo` does NOT depend on `forge_app` + +--- + +## Phase 5: Clean `forge_domain` to Pure Domain Types + +**Rationale:** `forge_domain` currently has 63 modules with `pub use *` glob exports, 39 dependencies (including `tokio`, `nom`, `regex`, `serde_yml`, `schemars`), and contains non-domain concerns like `ConsoleWriter` (I/O), `conversation_html.rs` (presentation), `http_config.rs` (infra config), `result_stream_ext.rs` (async stream utils). A domain layer should contain pure business types, value objects, and domain errors β€” nothing more. + +### Implementation + +- [ ] 5.1 Remove `ConsoleWriter` (already moved to `forge_port` in Phase 1). Remove `repo.rs` (already moved to `forge_port` in Phase 1). + +- [ ] 5.2 Move `conversation_html.rs` (HTML rendering of conversations) to `forge_display` or `forge_app::fmt` β€” this is presentation logic. + +- [ ] 5.3 Move `result_stream_ext.rs` to `forge_stream` β€” it contains `ResultStreamExt` which extends `Stream` and depends on `tokio`. This is an async utility, not a domain concern. + +- [ ] 5.4 Review `http_config.rs`: if it only defines configuration types (structs with Serde derives), it can stay. If it contains HTTP-specific behavior, move to `forge_port` or `forge_infra`. + +- [ ] 5.5 Review `template.rs`: if it defines `Template` as a generic value object, it can stay. If it depends on handlebars or rendering logic, move to `forge_app`. + +- [ ] 5.6 Review `xml.rs`: if it provides XML generation helpers for prompt formatting, move to `forge_app::system_prompt` or a dedicated formatting module. + +- [ ] 5.7 **Replace glob re-exports with explicit module exports**: In `crates/forge_domain/src/lib.rs`, replace every `pub use module::*;` with explicit `pub use module::{Type1, Type2, ...};` β€” or better, make modules themselves `pub mod` and let consumers use qualified paths. This eliminates namespace pollution (currently ~350+ types in a flat namespace). + +- [ ] 5.8 Remove the `pub type ArcSender = tokio::sync::mpsc::Sender>;` type alias from `forge_domain/src/lib.rs:129` β€” this is a runtime/infrastructure type alias, not a domain concept. + +- [ ] 5.9 Audit `forge_domain`'s Cargo.toml dependencies. After these moves, `tokio` should be removable (or at minimum downgraded to `tokio = { features = [] }` for basic types). The goal is zero async runtime dependency in the domain layer. + +### Verification + +- `forge_domain` has no `async fn` methods in any public trait +- `forge_domain` does not depend on `tokio` runtime features (only possibly `tokio::sync` for channel types if needed) +- No `pub use module::*` in `forge_domain/src/lib.rs` +- `forge_domain` public API is explicitly listed and documented + +--- + +## Phase 6: Resolve Cyclic Dependencies and OnceLock Late-Init Patterns + +**Rationale:** `ForgeAPI::init` (`crates/forge_api/src/forge_api.rs:90-128`) requires three separate post-construction `init_*` calls to resolve circular references between `ForgeServices` and `ForgeInfra` (via `ElicitationDispatcher` and `HookExecutor`). `OnceLock` late-init is a code smell indicating an incorrect dependency graph. The root cause: `ForgeElicitationDispatcher` needs `Arc` to fire hooks, but it lives inside `ForgeServices` β€” creating a self-referential cycle. + +### Implementation + +- [ ] 6.1 **Extract elicitation dispatching into an event bus pattern**: Define an `ElicitationEventBus` (using `tokio::sync::broadcast` or `mpsc`) that decouples the elicitation trigger (MCP handler in `forge_infra`) from the elicitation consumer (hook pipeline in `forge_services`). The bus is created before any layer, passed into both, and neither needs a reference to the other. + +- [ ] 6.2 **Extract hook model service into a callback-based design**: Instead of `ForgeHookExecutor` holding `Arc` (which is `Arc`), inject a `Box Future>>` closure at construction time. The closure is created in `ForgeAPI::init` from the services Arc, but the executor itself doesn't hold a reference to `Services`. + +- [ ] 6.3 Remove `init_elicitation_dispatcher()`, `init_hook_executor_services()`, and `init_elicitation_dispatcher(Arc)` from `ForgeServices` and `ForgeInfra`. All wiring happens at construction time without post-init steps. + +- [ ] 6.4 Remove the `OnceLock` fields from `ForgeElicitationDispatcher` and `ForgeHookExecutor`. Both receive their dependencies via constructor parameters. + +- [ ] 6.5 Simplify `ForgeAPI::init` to a straightforward linear construction sequence without any `init_*` ceremony. + +### Verification + +- No `OnceLock` usage for dependency injection in `forge_services` or `forge_infra` +- `ForgeAPI::init` contains no `init_*` method calls after initial construction +- `forge_infra` does not depend on `forge_services` (current backwards dependency at `crates/forge_infra/Cargo.toml:16` is eliminated) +- The dependency graph is strictly: `forge_api -> forge_services -> forge_app -> forge_port -> forge_domain`, `forge_api -> forge_repo -> forge_port -> forge_domain`, `forge_api -> forge_infra -> forge_port -> forge_domain` β€” no arrows pointing upward + +--- + +## Phase 7: Split `forge_repo` by Responsibility + +**Rationale:** `forge_repo` currently holds: LLM provider implementations (OpenAI, Anthropic, Bedrock, Vertex, Google β€” with full SSE/streaming, retry logic, and auth), SQLite persistence (Diesel ORM, migrations, connection pooling), gRPC clients (workspace indexing, validation, fuzzy search), and file-based repositories (agents, skills, plugins from markdown). These are 4 distinct infrastructure concerns with different dependency profiles β€” the AWS SDK alone adds significant compile time. + +### Implementation + +- [ ] 7.1 **Create `crates/forge_provider`**: Move all provider-related code: + - `provider/openai.rs`, `provider/openai_responses/`, `provider/anthropic.rs`, `provider/bedrock.rs`, `provider/google.rs`, `provider/opencode_zen.rs` + - `provider/event.rs`, `provider/retry.rs`, `provider/chat.rs`, `provider/provider_repo.rs` + - `provider/bedrock_cache.rs`, `provider/bedrock_sanitize_ids.rs` + - DTO types moved in Phase 4 + - Dependencies: `async-openai`, `aws-sdk-bedrockruntime`, `aws-credential-types`, `aws-smithy-*`, `google-cloud-auth`, `reqwest`, `reqwest-eventsource` + +- [ ] 7.2 **Create `crates/forge_db`**: Move all SQLite persistence: + - `database/` (pool, schema, migrations) + - `conversation/` (ConversationRepositoryImpl) + - Dependencies: `diesel`, `diesel_migrations` + +- [ ] 7.3 **Keep `forge_repo`** as a lightweight aggregator that holds `forge_provider`, `forge_db`, and the remaining file-based repos (agents, skills, plugins, snapshots) + gRPC clients. `ForgeRepo` struct still exists but with a much narrower scope β€” it aggregates actual repositories, not infrastructure passthrough. + +- [ ] 7.4 Alternatively, merge the gRPC clients into a `crates/forge_grpc` crate since they all share `tonic`/`prost` dependencies and the generated proto code. + +### Verification + +- `forge_provider` crate compiles independently with only `forge_domain`, `forge_port`, and external HTTP/LLM dependencies +- `forge_db` crate compiles independently with only `forge_domain` and `diesel` +- `forge_repo` no longer directly depends on `aws-sdk-*`, `diesel`, or `async-openai` β€” it depends on `forge_provider` and `forge_db` +- Individual provider tests run faster in isolation + +--- + +## Phase 8: Consolidate Redundant File System Traits + +**Rationale:** File operations are split across 5 separate traits: `FileReaderInfra`, `FileWriterInfra`, `FileRemoverInfra`, `FileInfoInfra`, `FileDirectoryInfra` (plus `DirectoryReaderInfra`). Each requires separate delegation in every layer. This granularity adds complexity without proportional benefit β€” in practice, most consumers need read + write + info together. + +### Implementation + +- [ ] 8.1 Define a unified `FileSystemPort` trait in `forge_port` that combines the 6 file-related traits into one interface. Keep logical grouping via method documentation sections. + +- [ ] 8.2 Provide a single implementation `ForgeFileSystem` in `forge_infra` that composes the current `ForgeFileReadService`, `ForgeFileWriteService`, `ForgeFileRemoveService`, `ForgeFileMetaService`, `ForgeCreateDirsService`, `ForgeDirectoryReaderService`. + +- [ ] 8.3 Consumers that need only a subset of file ops can still bound on the individual sub-traits if `FileSystemPort` is defined as a supertrait composition: `trait FileSystemPort: FileReaderInfra + FileWriterInfra + FileRemoverInfra + FileInfoInfra + FileDirectoryInfra + DirectoryReaderInfra {}`. + +- [ ] 8.4 This consolidation reduces the number of trait impls needed per layer from 6 to 1. + +### Verification + +- A single `impl FileSystemPort for ForgeInfra` replaces 6 separate `impl` blocks +- No consumer needs to list more than 2 file-related bounds + +--- + +## Phase 9: Clean Up `forge_api` Layer + +**Rationale:** `forge_api` defines an `API` trait with 52 methods that largely mirror `Services` methods. It adds value only through: (a) concrete type wiring in `ForgeAPI::init`, (b) lifecycle watcher management, (c) some composite operations (`commit`, `update_config` with cache invalidation). The 52-method trait itself is a maintenance burden. + +### Implementation + +- [ ] 9.1 **Remove `API` trait**: Make `ForgeAPI` a concrete struct with `pub` methods directly. The `API` trait provides no polymorphism benefit β€” there is exactly one implementation (`ForgeAPI`), and the trait is never used as `dyn API` or as a generic bound outside tests. + +- [ ] 9.2 If tests need a mock API, use a focused test trait or expose `ForgeAPI::new(mock_services, mock_infra)` directly. + +- [ ] 9.3 **Stop glob re-exporting**: In `forge_api/src/lib.rs`, replace `pub use forge_domain::{Agent, *};` with explicit re-exports of only the types that `forge_main` actually needs. Audit `forge_main` imports to determine the minimal set. + +- [ ] 9.4 Move watcher logic into `forge_services` if watchers are a pure services concern, or keep in `forge_api` if they require the fully wired stack. Document the rationale. + +### Verification + +- No `trait API` definition exists in the codebase +- `forge_api/src/lib.rs` has no `pub use *` statements +- `forge_main` compiles with explicit imports + +--- + +## Phase 10: Eliminate `InfraPluginRepository` Adapter Triplication + +**Rationale:** `InfraPluginRepository` is a thin adapter struct created 3 times in `ForgeServices::new` (`crates/forge_services/src/forge_services.rs:163-164`, `192-193`, `210-211`) to convert `Arc` into `Arc`. This exists because some services take `Arc` while the generic `F` implements `PluginRepository` but isn't `dyn`-compatible at the point of use. + +### Implementation + +- [ ] 10.1 Create a single `Arc` at the beginning of `ForgeServices::new` and pass the same instance to all three consumers (`ForgeMcpManager`, `ForgeCommandLoaderService`, `ForgeHookConfigLoader`). + +- [ ] 10.2 Remove the `InfraPluginRepository` adapter struct entirely β€” `Arc` can be cast to `Arc` directly when `F: PluginRepository + 'static`, using `Arc::clone(&infra) as Arc`. + +### Verification + +- No `InfraPluginRepository` struct exists +- Single `Arc` created once and shared + +--- + +## Execution Order and Dependencies + +``` +Phase 1 (forge_port) ← Foundation, must go first + ↓ +Phase 5 (clean forge_domain) ← Depends on Phase 1 (traits moved out) + ↓ +Phase 2 (decompose Services) ← Depends on Phase 1 (ports relocated) + ↓ +Phase 3 (eliminate delegation)← Depends on Phase 2 (smaller bounds) + ↓ +Phase 4 (extract DTOs) ← Independent of Phase 2/3, depends on Phase 1 + ↓ +Phase 6 (resolve cycles) ← Depends on Phase 3 (2 type params) + ↓ +Phase 7 (split forge_repo) ← Depends on Phase 3 + 4 + ↓ +Phase 8 (consolidate FS) ← Independent, can run after Phase 1 + ↓ +Phase 9 (clean forge_api) ← Depends on Phase 2 (Services decomposed) + ↓ +Phase 10 (cleanup adapter) ← Trivial, can run anytime +``` + +**Critical path:** Phase 1 β†’ Phase 5 β†’ Phase 2 β†’ Phase 3 β†’ Phase 6 + +**Parallelizable:** Phase 4 can run in parallel with Phases 2-3. Phase 8 can run after Phase 1 independently. Phase 10 is standalone. + +--- + +## Potential Risks and Mitigations + +1. **Massive merge conflicts during long-running refactoring** + Mitigation: Execute each phase as a single PR. Never have two phases in-flight simultaneously. Rebase frequently against main. + +2. **Breaking test infrastructure (`orch_spec` Runner)** + Mitigation: The `orch_spec::Runner` test harness implements the full `Services` trait. Phase 2 changes its shape. Update Runner's trait implementations incrementally β€” it must implement each group trait instead of the monolith `Services`. + +3. **Compile time regression from additional crate boundaries** + Mitigation: More crates = more parallelism in compilation. The provider crate (`forge_provider`) can compile in parallel with `forge_db` and `forge_services`. AWS SDK dependencies are already the bottleneck; isolating them in one crate prevents recompilation when unrelated code changes. + +4. **Phase 1 is a large cross-cutting change** + Mitigation: Use `pub use forge_port::*;` re-exports temporarily in `forge_domain` and `forge_app` during transition, so downstream code doesn't break until explicitly migrated. Remove re-exports only after all consumers are updated. + +5. **Service group boundaries may not be optimal** + Mitigation: The group traits in Phase 2 are soft boundaries. If during implementation a different grouping proves more natural (based on actual usage analysis of each consumer's bounds), adjust. The key invariant is: no group trait has more than 10 associated types. + +--- + +## Alternative Approaches + +1. **Dynamic dispatch instead of generics**: Replace `ForgeServices` with `ForgeServices` holding `Arc` fields. Eliminates all generic bounds explosion but introduces vtable overhead on every service call. Rejected: the codebase explicitly avoids `Box` per project guidelines. + +2. **Keep `Services` as-is but generate blanket impls with a proc macro**: A `#[service_locator]` macro could auto-generate the delegation boilerplate. Reduces visible code but doesn't fix the underlying coupling. Rejected: hides complexity instead of removing it. + +3. **Merge `forge_app` and `forge_services` into one crate**: Since the boundary between them is blurred, merging simplifies the dependency graph. Rejected: separating trait definitions (app) from implementations (services) enables test mocking and enforces interface discipline β€” it's the right separation, just needs cleaner execution. + +4. **Use Ambassador crate for delegation**: The `ambassador` crate can auto-derive trait delegation impls. Would eliminate ~800 lines of boilerplate in ForgeRepo/ForgeInfra. Considered viable as a transitional measure but doesn't fix the root cause (single-parameter F requiring all traits). Can be used as a tool during Phase 3 migration. diff --git a/plans/2026-04-11-plugin-system-finalization-v1.md b/plans/2026-04-11-plugin-system-finalization-v1.md new file mode 100644 index 0000000000..43a1fc0843 --- /dev/null +++ b/plans/2026-04-11-plugin-system-finalization-v1.md @@ -0,0 +1,173 @@ +# Plugin System Finalization + +## Objective + +Complete the remaining plugin system integration gaps: +1.

Verify this contract holds. + +2. **SkillListingHandler is owned by orchestrator, not by Services** + Mitigation: The reset call must flow from the UI layer (which owns the orchestrator) rather than from `reload_plugin_components`. This is documented in the trait at `crates/forge_app/src/services.rs:691-695`. Group B accounts for this architectural constraint. + +3. **`forge plugin list` may not exist as a CLI subcommand** + Mitigation: E5 explicitly flags this. If it doesn't exist, the shell handler can either: (a) use `_forge_exec_interactive -p "/plugin list"` to route through the REPL, or (b) a proper CLI subcommand is added. Option (a) is simpler but less clean; option (b) is the correct long-term solution. + +4. **Removing `dead_code` annotations may cause new compiler warnings** + Mitigation: Only remove annotations for methods that are actually wired in the same PR. Methods kept as future extension points (e.g., `add_hook()`) retain their `#[allow(dead_code)]` with updated comments. + +5. **Session hook cleanup race condition** + Mitigation: `clear_session()` is called after the SessionEnd dispatch completes (not during), so all SessionEnd hooks have finished before the cleanup runs. The `RwLock` ensures thread safety. + +## Alternative Approaches + +1. **For Group B (SkillListingHandler reset)**: Instead of threading the reset through the UI layer, introduce a `PluginReloadNotifier` event bus that the orchestrator subscribes to. More decoupled but adds complexity for a single call site. + +2. **For Group E (Shell plugin)**: Instead of creating a dedicated `_forge_action_plugin` handler, let `:plugin` fall through to `_forge_action_default` and add `plugin` to `built_in_commands.json` with type `BUILTIN`. This would require the Rust binary to support `forge plugin list` as a CLI subcommand (risk E5). Simpler shell code but requires more Rust changes. + +3. **For Group D (SessionHookStore)**: Remove `add_hook()`, `has_hooks()`, and `clear_session()` entirely since they're unused in production.
