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. Add handling in `scan_root`: + - When scanning `~/.claude/plugins/` and encountering a `cache/` or `marketplaces/` child directory, scan two levels deeper (author → plugin-or-version) looking for manifests. + - Alternatively, detect these known directory names and apply marketplace.json-based resolution. + + **Rationale:** Some Claude Code plugins are installed via npm/cache mechanisms that create versioned directory hierarchies. Forge should discover both layouts. + +- [x] **Task 1.4.

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. Count MCP servers from `.mcp.json` sidecar in trust prompt** + + **File:** `crates/forge_main/src/ui.rs` (around line 4864) + + Currently: + ```rust + let mcp_count = manifest.mcp_servers.as_ref().map(|m| m.len()).unwrap_or(0); + ``` + + Change to also parse the `.mcp.json` sidecar file at `/.mcp.json`, merging counts the same way `resolve_mcp_servers` does in `crates/forge_repo/src/plugin.rs:353-401`. Extract the parsing logic into a shared helper or duplicate the minimal parse-and-count logic inline. + + **Rationale:** Claude Code plugins typically declare MCP servers in `.mcp.json`, not in the manifest. Without this, the trust prompt always shows "MCP Servers: 0" for Claude Code plugins. + +- [x] **Task 2.3. 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 `${CLAUDE_PLUGIN_ROOT}` work in command strings. + +### Phase 4: `CLAUDE_PROJECT_DIR` and `CLAUDE_SESSION_ID` Aliases + +Similar to Phase 3, Claude Code hooks may also reference `CLAUDE_PROJECT_DIR` and other `CLAUDE_*` prefixed variables. + +- [x] **Task 4.1. Add remaining `CLAUDE_*` env var aliases for hooks** + + **File:** `crates/forge_app/src/hooks/plugin.rs` (env var construction block, lines 262-307) + + Add aliases: + - `CLAUDE_PROJECT_DIR` → same as `FORGE_PROJECT_DIR` + - `CLAUDE_SESSION_ID` → same as `FORGE_SESSION_ID` + + Only add these when the hook source is a `ClaudeCode` plugin (check `source.source == PluginSource::ClaudeCode`) to avoid polluting the env for Forge-native plugins. + + **Rationale:** Some Claude Code hooks reference `$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 `$CLAUDE_PROJECT_DIR` in their runtime logic. + +- [x] **Task 4.3. Update tests for all aliases** + + **Files:** Same as Task 3.3 plus any new tests needed for `CLAUDE_PROJECT_DIR` / `CLAUDE_SESSION_ID`. + + **Rationale:** Ensures complete test coverage for all Claude Code env var aliases. + +### Phase 5: Trust Prompt Modes Component Display (Optional Enhancement) + +Claude Code plugins may include `modes/` directories with custom operational modes. This is a lower-priority enhancement for display completeness. + +- [x] **Task 5.1. Add `modes` count to trust prompt COMPONENTS section** + + **File:** `crates/forge_main/src/ui.rs` (trust prompt section, around line 4878) + + Add a line: + ```rust + let modes_count = count_entries(&source, "modes"); + ``` + And display it in the COMPONENTS section if > 0. + + **Rationale:** Gives users visibility into plugin modes during the trust prompt. Modes are informational only — Forge doesn't execute them — but seeing "Modes: 36" helps users understand what the plugin contains. + +- [x] **Task 5.2. Add `modes` count to `/plugin info` and `/plugin list`** + + **Files:** `crates/forge_main/src/ui.rs` (functions `on_plugin_info` at line 4691, `format_plugin_components` at line 131) + + Add modes count alongside existing component counts. + + **Rationale:** Consistency between install prompt and info/list views. + +## Verification Criteria + +- `forge plugin install /path/to/marketplace/author` correctly resolves `marketplace.json` → installs only the `./plugin` subdirectory +- Trust prompt shows correct component counts: skills (7), commands (0), agents (0), hooks (present), MCP servers (1) for the claude-mem example +- Runtime `scan_root` of `~/.claude/plugins/` discovers plugins inside `marketplaces//` via `marketplace.json` indirection +- Hooks using `${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 — 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 — `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 — `marketplace.json` may point to non-existent directories** + Mitigation: Validate that `/` exists and contains a manifest; surface a clear error if not. + +4. **Performance — 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 — 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 — 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}` → `${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.
