The estimate may differ from the API's actual token count, especially for complex content (media, reasoning blocks). +- The migration adds a column to the `sessions` table, which is a one-time schema change. +- The UI fallback means the displayed value can still be stale (one request behind) in the edge case where `CurrentTokens` hasn't been populated yet. This is acceptable for now but could be improved with a backfill migration. + +**Open Questions:** +- The estimate could be more accurate by using the provider's token counter directly when available (fantasy provides token counts per step). +- A startup backfill migration to set `CurrentTokens = PromptTokens + CompletionTokens` for all existing sessions would eliminate the fallback entirely and make the UI accurate from the first render. + +## Alternatives + +### LLM/User-Driven Compaction via `new_session` Tool (PR #2333) + +An alternative approach was proposed in [PR #2333](https://github.com/charmbracelet/crush/pull/2333) by @taoeffect. It introduced: + +1. A **`new_session` tool** that allows the LLM to create a fresh session when context gets full, carrying forward a summary of progress and remaining work. +2. A **`` block** injected into the system prompt each turn, so the model can track its own context usage and proactively call `new_session` (default at ~75% context remaining). +3. A **compaction method toggle** (auto vs LLM/user-driven) selectable via the command palette, persisting across sessions in the data config. +4. A **UI renderer** for the tool's pending/completed states and a compaction method switching menu. + +### Why This Was Rejected + +We chose the simpler auto-summarization approach for now because: + +- **Less surface area**: The `new_session` approach requires a new tool, new config fields (`CompactionMethod`), new UI components (toggle, context status renderer), and changes to the system prompt injection layer. Our approach only adds a config option and a few lines in the agent loop. +- **No LLM dependency**: The auto-summarization is fully automated and doesn't rely on the model to recognize context pressure and decide to call a tool. The model can fail to trigger the tool (as seen in PR #2333's own fix: `compactionFlags()` was disabling the auto-summarize safety net in LLM mode). +- **No session fragmentation**: `new_session` creates entirely new sessions, which fragments conversation history and file version tracking (PR #2333 had to fix a UNIQUE constraint violation in file history as a result). Auto-summarization keeps everything in the same session. +- **Faster iteration**: This approach is simpler to test, debug, and iterate on. The `SummarizeThreshold` config option already gives users control over when summarization triggers. + +The LLM/user-driven approach may be worth revisiting later as a complementary feature — for example, allowing the model to explicitly request compaction when it detects a complex multi-step task that would benefit from a clean slate, even before hitting the context limit. + +## References + +- `internal/agent/agent.go` — token estimation, auto-summarization, hard guard +- `internal/config/config.go` — `SummarizeThreshold` option +- `internal/session/session.go` — `CurrentTokens` field +- `internal/db/migrations/20260608000000_add_current_tokens.sql` — schema migration +- `internal/ui/model/header.go` — header percentage display +- `internal/ui/model/sidebar.go` — sidebar context bar display diff --git a/.agents/docs/adr/0002-structured-tool-observation-for-parsing-failures.md b/.agents/docs/adr/0002-structured-tool-observation-for-parsing-failures.md new file mode 100644 index 0000000000..ce94346b39 --- /dev/null +++ b/.agents/docs/adr/0002-structured-tool-observation-for-parsing-failures.md @@ -0,0 +1,173 @@ +# ADR-0002: Structured Tool Observation for Parsing Failures + +## Status + +Accepted + +## Context + +### Original Behavior: Raw Errors in Session Messages + +Crush's agent harness originally included the raw error message and 400 Bad Request response from the inference API directly in the session's message history. This caused a critical failure: when a framework-level tool call validation error occurred (e.g., missing parameters, invalid JSON, malformed patterns), the error response was stored as a tool result in the session. The presence of this error message in the conversation history corrupted the session state — the session would become unusable and refuse further input, forcing the user to force-quit the application. + +### The Protective Strip + +To prevent sessions from becoming unusable, the error was handled by silently stripping the failed tool call and its error response from the conversation history before the next API request. This approach prevented the session corruption issue, but introduced a critical problem: the agent was left "blind" to why its tool call failed. + +### The Blind Agent Problem + +When the TUI displayed a tool error to the user, the model had no corresponding context in the conversation history to explain the failure. This led to the model confidently repeating the same broken tool call, producing repetitive and incorrect error messages, and in some cases entering retry loops that degraded the user experience. + +The core challenge was balancing two competing concerns: + +1. **Session integrity**: The conversation history must not contain raw error responses that corrupt the session and make it unusable. +2. **Agent awareness**: The model must understand *why* a tool call failed so it can self-correct. + +## Decision + +We implemented a **Structured Tool Observation** pattern that intercepts framework-level validation errors, translates them into human-readable, actionable messages, and injects them as synthetic tool result messages into the conversation history — rather than silently stripping the failed call. + +### Architecture + +The implementation spans three layers: + +#### 1. Error Translation Layer (`internal/agent/tool_observation.go`) + +The `translateToObservation` function converts framework-level validation errors into semantic, model-friendly messages. It matches error message patterns and produces structured "Tool Observation" messages that explain the failure: + +``` +Tool Observation: Your previous attempt failed because the required parameter "pattern" was missing for tool "glob". Please review the tool definition and provide all necessary inputs. +``` + +The translation layer recognizes specific error categories: + +| Error Pattern | Translation | +|---|---| +| `missing required parameter` | Identifies the specific missing parameter (extracted via `extractParamName`) and the tool name. | +| `invalid pattern` | Instructs the model to use standard regex syntax. | +| `invalid json` / `malformed` / `parse error` | Instructs the model to ensure valid JSON with quoted keys. | +| `extra data` | Instructs the model to provide only expected inputs. | +| `context overflow` / `too long` / `overflow` | Instructs the model to provide shorter input. | +| Generic tool errors | Provides the raw error message with guidance to review the tool definition. | + +The `injectToolObservation` method on `sessionAgent` creates a synthetic `message.Tool` message with `IsError: true` and appends it to the session's message store, preserving the original tool call ID so it passes the orphan filter. + +#### 2. Recovery Flow in the Coordinator (`internal/agent/coordinator.go:270-314`) + +The coordinator's `Run` method implements a three-phase recovery strategy for 400 Bad Request errors: + +1. **First retry**: On a 400 error, retry once. vLLM's tool call parser can produce malformed output that triggers context overflow; the model often produces valid output on the second attempt. + +2. **Strip + Observation**: If the second attempt also fails, the coordinator: + - Calls `injectToolObservation` to insert the translated error message into the session. + - Tags the context with `WithStripLastToolCall` so the agent skips the last assistant tool call when building the conversation history. + - Runs the agent again with the stripped history and the injected observation. + +3. **Hard stop**: If the third attempt also fails with 400, the coordinator does **not** retry further. The error is treated as permanent (e.g., model misconfiguration, invalid parameters). + +```go +// Pseudocode of the recovery flow: +if c.isBadRequest(originalErr) { + result, originalErr = run() // Attempt 1 (original) + if c.isBadRequest(originalErr) { + result, originalErr = run() // Attempt 2 (retry) + if c.isBadRequest(originalErr) { + c.injectToolObservation(stripCtx, ...) // Inject observation + result, originalErr = c.currentAgent.Run(stripCtx, ...) // Attempt 3 (strip + observe) + // If still 400: do NOT retry further + } + } +} +``` + +The `isBadRequest` function (`coordinator.go:1149`) filters 400 errors to only those that are potentially recoverable — matching on keywords like `tool`, `malformed`, `invalid json`, `extra data`, `context overflow`, and `parse error`. This prevents retrying on permanent errors (e.g., model not found). + +#### 3. Conversation History Stripping (`internal/agent/agent.go:1016`) + +When the `IsStripLastToolCall` context flag is set, the agent's `preparePrompt` method identifies the last assistant message with tool calls and skips its tool call parts when building the fantasy conversation history. This prevents the malformed tool call from being re-sent to the API while still preserving the rest of the conversation context. + +#### 4. System Prompt Constraint (`internal/agent/agent.go:454`) + +A `` block is appended to the system prompt: + +``` +If you receive a 'Tool Observation' in a tool result message, you are required to analyze the error and adjust your strategy before retrying. Do not repeat the same failed tool call with the same input. Review the tool definition, correct the input parameters, and ensure valid JSON syntax. +``` + +This gives the model explicit instructions on how to respond when it receives a Tool Observation. + +#### 5. Consecutive Failure Guardrail (`internal/agent/loop_detection.go`) + +A separate loop detection mechanism tracks consecutive tool failures per tool name across the last 10 steps (`loopDetectionWindowSize`). If a specific tool fails more than 2 times in a row (`toolFailureMaxCount`), the system treats it as a loop and prevents further retries for that tool. A successful call for the same tool resets the counter. + +```go +// Key constants: +loopDetectionWindowSize = 10 +toolFailureMaxCount = 2 +``` + +The `hasConsecutiveToolFailures` function scans steps backwards, tracking failure counts per tool name. A missing result (no tool result for a call) is also treated as a failure. + +### Context Key Design (`internal/agent/runid.go`) + +Two unexported context keys coordinate the flow between coordinator and agent: + +- `stripLastToolCallContextKey`: Signals the agent to skip the last assistant tool call. +- `toolObservationErrorKey`: Carries the original validation error and tool name from the coordinator to the agent. + +These keys are passed via `context.WithValue` and checked via `IsStripLastToolCall` and `ToolObservationErrorFromContext`, keeping the coordinator-agent boundary clean without changing function signatures. + +## Consequences + +**Positive:** + +- **Informed self-correction**: The model understands *why* a tool call failed and can adjust its input on the next attempt. This eliminates the "blind retry" problem that previously caused repetitive, confident errors. +- **Preserved context**: The conversation history reflects reality — the TUI error message matches what the model sees in the context window. +- **Reduced noise**: The model is not forced to re-reason over its own broken input; it receives a clear, translated explanation instead. +- **Loop prevention**: The combination of the hard stop (3 attempts max) and the consecutive failure guardrail (`toolFailureMaxCount = 2`) prevents infinite retry loops. +- **Improved stability**: The structured observation has measurably improved the stability of the Crush agent in production, particularly for tools with strict input requirements (e.g., `glob`, `view`, `edit`). + +**Negative:** + +- **Increased message history**: Injecting synthetic tool result messages adds entries to the session, slightly increasing the context window usage. +- **Translation fidelity**: The `translateToObservation` function relies on string matching against error messages. If the underlying framework changes error message formats, translations may become stale. +- **Complexity**: The three-phase recovery flow (retry → strip + observe → hard stop) is more complex than the previous simple strip approach. This increases the cognitive load for future maintainers. +- **Hard-coded thresholds**: The retry limit (3 attempts) and failure count (2) are hard-coded constants. Different models may recover from errors with varying success rates, making a configurable policy desirable in the future. + +**Open Questions:** + +- **Configurable policy**: The RFC proposes a `ToolPolicy` struct with `MaxRetries`, `Strict`, and `RequiresHuman` fields to make the failure handling configurable per-tool. This would allow users to define safety profiles based on the tool's risk level. +- **Translation robustness**: The error translation relies on substring matching. A more robust approach might parse structured error types from the framework rather than matching on error message strings. +- **Per-tool failure limits**: The current `toolFailureMaxCount = 2` applies uniformly to all tools. Some tools (e.g., `bash`) may tolerate more retries than others (e.g., `edit`). + +## Alternatives + +### Silent Strip (Previous Approach) + +The original approach silently stripped failed tool calls from the conversation history. This prevented infinite loops but left the agent blind to failures, causing it to repeat the same broken calls with confidence. + +**Rejected because**: The blind retry problem caused significant user-facing issues — the agent repeatedly produced the same errors without understanding why, degrading the user experience and making the agent appear unreliable. + +### Full Error Propagation to User + +An alternative would be to immediately surface tool failures to the user without attempting any retry. This would be the simplest approach but would sacrifice the agent's ability to self-correct on transient errors (e.g., vLLM parser producing malformed output that succeeds on retry). + +**Rejected because**: Many 400 errors are transient and recoverable. The three-phase recovery strategy captures these cases while still preventing infinite loops. + +### Strip Without Observation + +Strip the failed tool call but do not inject a Tool Observation message. This is simpler than the current approach but still leaves the agent without context about why the call failed. + +**Rejected because**: Without the observation, the agent still lacks the information needed to self-correct.

The MCP server name is preserved as an additional attribute. + +### 6. `internal/otel/otel_test.go` — Tests + +Added tests for the new GenAI helper functions: +- `TestStartGenAISpan_NoEndpoint` — verifies span creation with full GenAI attributes +- `TestSetGenAIAttributes_NilSpan` — nil-safety +- `TestRecordGenAIMetrics_NoMetrics` — metrics no-op safety + +## Consequences + +**Positive:** +- **Interoperability**: Crush traces are now compatible with the broader GenAI observability ecosystem. Tools like W&B Weave, LangSmith, Arize Phoenix, and Langfuse all understand the `gen_ai.*` attribute namespace and can correlate Crush traces with traces from other GenAI applications. +- **Standardized attributes**: All spans now include `gen_ai.operation.name`, which is the primary discriminator for filtering and grouping traces in OTel-compatible backends. +- **Provider identification**: The `gen_ai.provider.name` attribute enables filtering traces by provider (e.g., `openai`, `anthropic`, `aws.bedrock`). +- **Token tracking**: Token usage is now tracked with the standard `gen_ai.usage.*` attributes, making it easy to compute cost and performance metrics. +- **Backward compatibility**: Existing Crush-specific metrics are preserved, so existing dashboards and alerting rules continue to work. +- **Future-proof**: The helper functions (`StartGenAISpan`, `SetGenAIAttributes`) make it easy to add new GenAI instrumentation points without duplicating attribute logic. + +**Negative:** +- **Span name changes**: The span names have changed (e.g., `agent.turn` → `invoke_agent Crush Agent`). Existing trace queries that reference the old span names will need to be updated. +- **Larger span payloads**: Each span now includes many more attributes (up to 30+ GenAI attributes). This increases the size of each span in the trace data. However, OTel backends typically drop attributes that are not sampled or not configured for export, so this impact is limited in practice. +- **No streaming metrics yet**: The `gen_ai.client.operation.time_to_first_chunk` metric is defined but not yet populated in the agent loop. This can be added in a future iteration by tracking the time between the LLM request start and the first `OnTextDelta` callback. + +**Open Questions:** +- Should we populate `gen_ai.conversation.id` with the session ID? This would enable correlating all spans from a single conversation. +- Should we populate `gen_ai.input.messages` and `gen_ai.output.messages` as opt-in attributes? These contain PII and should be gated behind a config option. +- Should we add `gen_ai.request.stream` to indicate whether streaming was used? +- The `gen_ai.client.operation.time_to_first_chunk` metric is defined but not yet recorded — this is a known gap. + +## Alignment with RFC + +The RFC outlined a phased implementation plan. Here is the current status: + +| RFC Phase | Description | Status | +|---|---|---| +| Phase 1: OTel SDK Foundation | Tracer provider, OTLP exporter, config | **Done** (previous session) | +| Phase 2: Agent Turn Spans | `agent.turn`, `agent.turn.llm.request`, `agent.turn.prepare` | **Done** (previous session, renamed + gen_ai attrs in this session) | +| Phase 3: Tool Call Spans | `tool.call` wrapper, individual tool spans | **Partially done** — `tool.call` renamed to `execute_tool` with gen_ai attrs. Individual tool spans (`tool.bash`, `tool.edit`, etc.) not yet added. | +| Phase 4: Hooks, LSP, MCP | `hook.run`, `lsp.init`, `mcp.tool_call` | **Done** (previous session, MCP renamed to `execute_tool` with gen_ai attrs in this session) | +| Phase 5: HTTP Server & Database | HTTP request spans, DB query spans | **Not started** | +| Phase 6: Metrics | Counters and histograms | **Done** (previous session, gen_ai standard metrics added in this session) | + +The RFC also envisioned: +- Per-tool spans (`tool.bash`, `tool.edit`, etc.) — not yet implemented +- LSP request spans (`lsp.request`) — not yet implemented +- HTTP server spans (`http.request`) — not yet implemented +- DB query spans (`db.query`) — not yet implemented + +## Alternatives + +### Option A: Replace Crush-specific metrics entirely + +Replace `crush.tool_calls.total`, `crush.llm_requests.total`, etc. with the GenAI standard metrics and remove the Crush-specific ones. + +**Rejected** because it would break existing dashboards and alerting rules. The dual-metric approach (both Crush-specific and GenAI standard) provides a safe migration path. + +### Option B: Use only the OTel Go SDK's built-in semantic conventions + +Use the `go.opentelemetry.io/otel/semconv/*` packages directly instead of defining our own attribute keys. + +**Rejected** because the OTel Go semconv packages don't yet include GenAI-specific attribute keys. The GenAI conventions are still in development and maintained in a separate repository (`github.com/open-telemetry/semantic-conventions-genai`). Defining our own attribute keys gives us control over the naming and makes it easier to update when the official Go semconv package catches up. + +### Option C: Only add the `gen_ai.operation.name` attribute + +Add just the single required attribute (`gen_ai.operation.name`) to each span and leave the rest of the instrumentation unchanged. + +**Rejected** because a single attribute provides very limited observability value.

Template Context Injection (`internal/agent/coordinator.go:476-531`) + +The `getProviderOptions` switch case for `openaicompat` and `hyper` providers now injects the policy: + +```go +case openaicompat.Name, hyper.Name: + extraBody := make(map[string]any) + + // Inject chat_template_kwargs so Jinja-based providers can + // preserve and enable thinking tags in the model output. + policy := defaultProviderPolicy() + extraBody["chat_template_kwargs"] = policy.ChatTemplateKwargs + + // ... provider-specific thinking/reasoning config follows ... + + mergedOptions["extra_body"] = extraBody +``` + +**How `chat_template_kwargs` interacts with Jinja templates:** + +The `chat_template_kwargs` map is forwarded through the Fantasy provider layer into the OpenAI-compatible HTTP request body under the `extra_body` key. Jinja-based chat templates (used by providers like Hyper, vLLM, and Catwalk backends) read these kwargs to control template behavior: + +- **`preserve_thinking: true`** — Tells the Jinja template to preserve the models `` tags in the output rather than stripping them. Without this, the template may emit raw reasoning text that the tool-parser cannot distinguish from tool instructions. +- **`enable_thinking: true`** — Tells the template to actively wrap the models reasoning content in `` tags. This ensures the parser can correctly identify and separate reasoning from tool call instructions. + +Together, these kwargs force the Jinja template to produce output like: + +``` + +I need to search for the file first. + +``` + +This prevents the tool-parser from misinterpreting reasoning text as malformed tool instructions, which was the root cause of missing required parameters, invalid JSON, and extra data errors. + +**Provider coverage:** + +| Provider | `extra_body` path | Template support | +|---|---|---| +| OpenAI-compatible | `extra_body.chat_template_kwargs` | Yes (via Jinja) | +| Hyper | `extra_body.chat_template_kwargs` + `extra_body.thinking` | Yes (via Jinja) | +| Catwalk (inference.ai) | `extra_body.chat_template_kwargs` + `extra_body.reasoning` / `extra_body.enable_thinking` | Yes (via Jinja) | + +For Catwalk backends, the `enable_thinking` field is also set dynamically based on `model.ModelCfg.Think` (e.g., `extraBody["enable_thinking"] = model.ModelCfg.Think` for Alibaba Singapore). + +### 3. Tool Observation Integration (`internal/agent/tool_observation.go`, `internal/agent/coordinator.go:1198-1244`) + +The `translateToObservation` function converts framework-level validation errors into human-readable, actionable messages: + +```go +func translateToObservation(err error, toolName string) string +``` + +Error categories recognized and translated: + +| Error Pattern | Translation | +|---|---| +| `missing required parameter` | Identifies the specific missing parameter (extracted via `extractParamName`) and the tool name. | +| `invalid pattern` | Instructs the model to use standard regex syntax. | +| `invalid json` / `malformed` / `parse error` | Instructs the model to ensure valid JSON with quoted keys. | +| `extra data` | Instructs the model to provide only expected inputs. | +| `context overflow` / `too long` / `overflow` | Instructs the model to provide shorter input. | +| Generic tool errors | Provides the raw error message with guidance to review the tool definition. | + +The `injectToolObservation` method on `sessionAgent` (`tool_observation.go:68`) creates a synthetic `message.Tool` message with `IsError: true` and appends it to the session message store, preserving the original tool call ID so it passes the orphan filter. + +The coordinator-level `injectToolObservation` (`coordinator.go:1202`) finds the last assistant message with tool calls and injects the translated observation: + +```go +func (c *coordinator) injectToolObservation(ctx context.Context, sessionID string, err error) +``` + +This is called during the three-phase 400 Bad Request recovery flow (`coordinator.go:296-328`): + +1. **First retry**: On a 400 error, retry once. +2. **Strip + Observation**: If the second attempt also fails, inject the tool observation, tag the context with `WithStripLastToolCall`, and run again. +3. **Hard stop**: If the third attempt also fails with 400, do NOT retry further. + +### 4. Single-Tool Constraint (`internal/agent/templates/coder.md.tpl:21`) + +A new rule in the critical rules section enforces sequential tool calls: + +``` +16. **SINGLE TOOL CALL**: You must issue tool calls one at a time. Do not attempt to use multiple tools in a single response block. Wait for the result of the first tool before calling the next. +``` + +This constraint is necessary because the vLLM XML parser (used by many local model providers) fails when the model produces multiple concurrent tool blocks in a single response. By forcing sequential tool calls, the model avoids triggering the parser bug entirely. + +## How the Layers Work Together + +The fix uses four interrelated layers that operate at different stages of the pipeline: + +### Layer 1: Template Context Injection (Prevention) + +`chat_template_kwargs` is injected into the request body **before** the API call is sent. This ensures the models reasoning output is properly wrapped in `` tags, preventing the tool-parser from misinterpreting reasoning as tool instructions. + +### Layer 2: Tool Observation Integration (Recovery) + +When a tool call fails despite prevention, `translateToObservation` converts the raw error into a semantic message, and `injectToolObservation` inserts it into the conversation history. This gives the model the context it needs to self-correct on the next attempt. + +### Layer 3: Single-Tool Constraint (Enforcement) + +The system prompt constraint prevents the model from attempting parallel tool calls, which eliminates the vLLM XML parser bug as a failure mode entirely. + +### Layer 4: Provider Policy (Abstraction) + +The `ProviderPolicy` struct provides a unified entry point for thinking-related configuration, making it easy to add provider-specific overrides in the future without scattering changes across the codebase. + +## Where It Could Grow (If Needed) + +### Config-driven policy overrides + +Users could configure `ChatTemplateKwargs` per-provider or per-model: + +```json +{ + "provider_policy": { + "openaicompat": { + "preserve_thinking": true, + "enable_thinking": true + }, + "hyper": { + "preserve_thinking": false, + "enable_thinking": true + } + } +} +``` + +### Provider-specific template kwargs + +Not all providers support `chat_template_kwargs`. A future enhancement could allow providers to declare their supported kwargs, and the coordinator could conditionally inject them. + +### Similarity-based error translation + +The `translateToObservation` function relies on substring matching. A more robust approach could parse structured error types from the Fantasy framework rather than matching on error message strings. + +### Logging + +Add `slog.Warn` in `injectToolObservation` when a tool observation is injected, including: + +- Session ID +- Tool name +- First 200 chars of the error message + +This would help debug which models/patterns trigger tool failures most often. + +## References + +- `internal/agent/coordinator.go:83-100` — `ProviderPolicy` struct and `defaultProviderPolicy` +- `internal/agent/coordinator.go:476-531` — `chat_template_kwargs` injection in `getProviderOptions` +- `internal/agent/tool_observation.go` — `translateToObservation`, `extractParamName`, `injectToolObservation` +- `internal/agent/tool_observation_test.go` — Test coverage for translation and parameter extraction +- `internal/agent/coordinator.go:1198-1244` — Coordinator-level `injectToolObservation` +- `internal/agent/coordinator.go:296-328` — Three-phase 400 Bad Request recovery flow +- `internal/agent/templates/coder.md.tpl:21` — Single-tool constraint in system prompt +- ADR: `.agents/docs/adr/0002-structured-tool-observation-for-parsing-failures.md` +- RFC: `.agents/docs/rfc/preserve-thinking.md` diff --git a/.agents/docs/fixes/FIX-0004-queued-message-duplication.md b/.agents/docs/fixes/FIX-0004-queued-message-duplication.md new file mode 100644 index 0000000000..666c2119fb --- /dev/null +++ b/.agents/docs/fixes/FIX-0004-queued-message-duplication.md @@ -0,0 +1,117 @@ +# Fix: Queued Message Duplication Causing Context Window Overflow + +## Summary + +Queued messages were sent to the LLM inference API twice per turn, causing exponential context window bloat that rapidly consumed the context limit and triggered infinite retry loops. + +## Root Cause + +The agent's queued message handling had two overlapping code paths that both appended queued messages to the API history: + +### Path 1: `PrepareStep` callback (line ~426) + +Inside `agent.Stream()`, the `PrepareStep` callback created queued messages in the DB and appended them to `prepared.Messages`: + +```go +queuedCalls, _ := a.messageQueue.Get(call.SessionID) +a.messageQueue.Del(call.SessionID) +for _, queued := range queuedCalls { + userMessage, createErr := a.createUserMessage(callContext, queued) + if createErr != nil { + return callContext, prepared, createErr + } + prepared.Messages = append(prepared.Messages, userMessage.ToAIMessage()...) +} +``` + +### Path 2: Recursive `Run()` call (line ~793) + +After streaming completed, if queued messages remained, a recursive `Run()` was triggered: + +```go +queuedMessages, ok := a.messageQueue.Get(call.SessionID) +if !ok || len(queuedMessages) == 0 { + return result, err +} +skipRunComplete = true +firstQueuedMessage := queuedMessages[0] +a.messageQueue.Set(call.SessionID, queuedMessages[1:]) +return a.Run(ctx, firstQueuedMessage) +``` + +The recursive call's `getSessionMessages()` fetched all messages from the DB (including the queued ones created in Path 1), and `preparePrompt()` converted them to API history. + +### The Duplication Loop + +1. **Turn N**: `Run()` calls `getSessionMessages()` → `preparePrompt()` → `agent.Stream()` +2. **Inside `agent.Stream()`**: `PrepareStep` creates queued messages in DB and appends them to `prepared.Messages` (sent to API) +3. **After streaming**: Recursive `Run()` is triggered +4. **Recursive `Run()`**: `getSessionMessages()` fetches all DB messages (including queued ones from step 2) → `preparePrompt()` converts them to history → `agent.Stream()` sends them to API +5. **Result**: Queued messages appear in the API history **twice** — once from the current turn's `PrepareStep` append, and again from the recursive call's normal flow + +Each turn, the duplication compounded, rapidly consuming the context window. + +## Fix + +Three changes in `internal/agent/agent.go`: + +### 1.

Frozen entries (where `Finished()` returns true) skip re-rendering. This works well for stable items but invalidates on width changes. + +2. **Item-level cache** (`chat/messages.go`): `cachedMessageItem` stores rendered output by width. Each message type caches its own output, invalidating when content changes. + +3. **Draw cache** (`model/chat.go`): The `chatDrawCache` pre-decodes the full `list.Render()` output into a `uv.ScreenBuffer`, avoiding per-frame ANSI reparse. However, it's invalidated on every content change — which happens on every streaming tick. + +The gap: **the draw cache is per-frame, not per-item**. When any message changes, the entire rendered string is re-decoded. During streaming, this means full ANSI decode + buffer creation every frame. Additionally, there is no cap on the number of messages in the list, so a session with 200+ items means 200+ cached entries, each consuming memory and layout computation time on scroll/resize. + +## Proposed Solution + +Implement a layered set of optimizations, each addressing a different part of the rendering pipeline. + +### Phase 1: Message Cap (Highest ROI) + +Limit the number of messages kept in the UI list. Old messages remain in session data but are removed from the render pipeline. + +```go +// In internal/ui/model/chat.go + +const maxMessages = 300 + +func (m *Chat) SetMessages(msgs ...chat.MessageItem) { + if len(msgs) > maxMessages { + msgs = msgs[len(msgs)-maxMessages:] + } + m.list.SetItems(msgs...) +} +``` + +**Why 300?** A typical session with 3-4 tool calls per assistant response yields ~15-20 messages per round. 300 messages covers ~15-20 rounds, which is well beyond what a user would need to scroll back through in a single session. + +**Trade-off:** Users can't scroll to the very top of very long sessions. However, they can still view old messages by opening the session in the session list (which loads the full history). For most use cases, the last 15-20 rounds of conversation is the relevant context. + +**Implementation notes:** +- The cap is applied at the UI layer only, not the session data layer +- When loading a session with more than `maxMessages` items, only the tail is shown +- A "load more" button could be added later if needed (see Future Potential) + +### Phase 2: Assistant Message Truncation + +Apply the same truncation pattern used for tool outputs (`responseContextHeight = 10` in `chat/tools.go`) to assistant messages with large content blocks (thinking, code, tool results). + +```go +// In internal/ui/chat/assistant.go + +const assistantMessageMaxLines = 50 + +// When rendering an assistant message, truncate content beyond +// assistantMessageMaxLines, showing a "N lines hidden" indicator +// that can be expanded by the user. +``` + +This prevents a single assistant message with a large tool output or thinking block from dominating the viewport and cache. + +### Phase 3: Layered Draw Cache + +Replace the single monolithic `chatDrawCache` with per-item screen buffers. On each frame: + +1. **Stable items** (not streaming, no content change): Use their cached `uv.ScreenBuffer` directly. +2. **Changed items** (streaming, new content): Re-render only those items. +3. **Composed output**: Blit stable buffers + newly rendered items into the final screen area. + +This eliminates the full-string re-decode on every streaming tick. Only the streaming item's buffer is recreated; all others are reused. + +**Implementation sketch:** +```go +type itemDrawCache struct { + renderHash string // simple hash of rendered content + buf uv.ScreenBuffer +} + +type layeredDrawCache struct { + items map[chat.MessageItem]*itemDrawCache +} + +func (c *layeredDrawCache) Draw(scr uv.Screen, area uv.Rectangle, items []chat.MessageItem) { + for i, item := range items { + entry := c.getOrRebuild(item, i) + entry.buf.Draw(scr, itemArea) + } +} +``` + +**Complexity:** Higher than Phase 1. Requires tracking per-item render hashes and managing buffer lifetimes. Worth doing once Phase 1 is proven effective. + +### Phase 4: Streaming Debounce + +During streaming, batch updates so rendering happens at most once every 50-100ms instead of on every tick. This reduces the number of draw cache invalidations during active streaming. + +```go +// In the agent/stream handler +const streamRenderInterval = 80 * time.Millisecond + +// Use a timer to throttle render messages +streamTimer := time.NewTimer(streamRenderInterval) +defer streamTimer.Stop() + +for chunk := range streamCh { + appendChunk(chunk) + select { + case <-streamTimer.C: + m.refreshChat() + streamTimer.Reset(streamRenderInterval) + default: + // Skip this frame + } +} +``` + +**Trade-off:** Streaming content appears slightly less smooth (updated at ~12fps instead of 60fps), but the difference is imperceptible for text streaming. The performance gain is significant: fewer draw cache invalidations per second. + +### Phase 5: Smaller Screen Buffer + +Currently, `View()` creates a `uv.NewScreenBuffer(m.width, m.height)` for the full terminal dimensions. The chat viewport is only a fraction of this. Use a buffer sized to the chat area only, and compose it with header/status/editor regions separately. + +```go +// Instead of: +canvas := uv.NewScreenBuffer(m.width, m.height) + +// Use: +chatHeight := m.layout.main.Dim().Height +canvas := uv.NewScreenBuffer(m.layout.main.Dim().Width, chatHeight) +``` + +**Impact:** Reduces the number of cells processed by `canvas.Render()` from ~20,000 (full terminal) to ~3,000 (chat area only). The header, status bar, and editor are small enough that their individual renders are negligible. + +## Existing Optimizations (Already in Place) + +Before implementing, note what's already working well: + +- **Viewport-bounded list rendering**: `list.Render()` only renders items within the viewport, bounded by `l.height` lines. Never processes beyond the visible budget. +- **Frozen entries**: Once `Finished()` returns true, items are cached and never re-rendered. +- **Tool output truncation**: `responseContextHeight = 10` limits tool output display. +- **Item-level caching**: `cachedMessageItem` stores rendered output by width. + +The proposed changes build on these foundations rather than replacing them. + +## Charm Package Support + +- **Ultraviolet**: Provides optimized screen buffer rendering with cell-copy operations.

You can check the last message in that slice to see if it was a failed tool call, then append your "Observation" message before returning the `prepared` result. + + + +# Future Potential + +### "Configurable Policy" + +The failure max count is hard-coded to 2 currently. Different models may recover from errors better than others. So there is some value in having it be configurable. However, instead of a raw `failureMaxCount` setting, we could implement a **Policy-based configuration**. This is a much more "Architect-friendly" way to handle it: + +``` +type ToolPolicy struct { + MaxRetries int + Strict bool // If true, stop on first failure for this tool + RequiresHuman bool // If true, pause and ask human after failure +} +``` + +This way, we aren't just giving the user a "knob" to turn; we are giving them the ability to define the **safety profile** of the agent based on the tool's risk level.

Injecting system-level reminders as user messages conflates instructions with conversation history, which can confuse the model about which user message is the latest one to respond to. + +2. **No separation of concerns** — System-level instructions (todo list reminders, feature hints) should be in the system message, not the conversation history. + +## Current message flow + +``` +[0] User: todo list is empty ← changes every turn +[1] User: "how do I define auto-summarization?" +[2] Assistant: (answers) +[3] User: "review unstaged changes" +[4] Assistant: (should answer [3]) +``` + +The model should respond to [3] because it's the last user message. But the system_reminder at [0] is a user message that changes content every turn, which can interfere with the model's understanding of the conversation structure. + +## Proposed solution + +Move the system_reminder content into the actual system message via the `fantasy.PrepareStepResult.System` field. The fantasy library already supports dynamic system prompts per-call through the `PrepareStep` function. + +### How it works + +The fantasy library's `AgentOption` `WithPrepareStep()` allows injecting dynamic content per-call: + +```go +PrepareStep: func(callContext context.Context, options fantasy.PrepareStepFunctionOptions) (_ context.Context, prepared fantasy.PrepareStepResult, err error) { + prepared.Messages = options.Messages + // ... existing code ... + + // NEW: Set dynamic system prompt content + dynamicSystem := buildDynamicSystemPrompt() // todo list state, etc. + prepared.System = &dynamicSystem + + return callContext, prepared, nil +} +``` + +The `prepared.System` field is a `*string` that gets merged with the static system prompt set via `fantasy.WithSystemPrompt()` at agent creation time. + +### Changes required + +1. **`internal/agent/agent.go`** — Remove the user-message-based system_reminder injection from `preparePrompt()` (lines 1016-1025) + +2. **`internal/agent/agent.go`** — In the existing `PrepareStep` function (line 417), set `prepared.System` to include the dynamic state (todo list reminders, etc.) + +3. **`internal/agent/agent.go`** — Create a `buildDynamicSystemPrompt()` function that returns the current dynamic state as a string + +### Implementation considerations + +**CRITICAL: System prompt concatenation** — `fantasy.WithSystemPrompt()` sets the static system prompt at agent creation time. The `PrepareStep` function's `prepared.System` field may **overwrite** rather than append. If so, retrieve the static prompt and concatenate: + +```go +staticPrompt := a.systemPrompt.Get() +dynamicPrompt := a.buildDynamicSystemPrompt() +combined := staticPrompt + "\n\n" + dynamicPrompt +prepared.System = &combined +``` + +Verify the actual behavior by checking how fantasy merges `WithSystemPrompt()` with `PrepareStepResult.System`. If fantasy already concatenates, the simpler form works. **Test this first** — an incorrect assumption here breaks the entire system prompt. + +**CRITICAL: Context window tax** — The dynamic system prompt is sent on **every `Run()` call**, consuming tokens each time. Keep `buildDynamicSystemPrompt()` concise: + +- Use short labels and abbreviations where possible +- Only include relevant state (e.g., active todo items, not completed ones) +- Consider summarizing long todo lists rather than listing all items +- Monitor token usage in early testing to catch unexpected bloat + +This is fine for now, but keep an eye on it if you ever scale to very long conversation histories. If the todo list grows to 50 items, that's 50 items worth of tokens being sent to the model on every single turn. + +**CRITICAL: State sanitization and truncation** — `buildDynamicSystemPrompt()` is called on every `Run()` and feeds directly into the API call. It **must not crash** the `PrepareStep` pipeline. Handle corruption gracefully: + +- **Truncate oversized content** — If the todo list or any state exceeds a reasonable size (e.g., 2000 characters), truncate and append a note like `"[truncated, N items omitted]"` +- **Sanitize malformed strings** — Strip or escape control characters, null bytes, or other non-printable characters that could corrupt the prompt +- **Log errors, don't panic** — If state is corrupted, log a warning and return a safe fallback string (e.g., `"Dynamic state unavailable."`) rather than propagating an error that could abort the entire turn +- **Be idempotent** — Calling the function multiple times with the same state must produce the same output. No side effects, no shared mutable state + +Example: + +```go +func (a *sessionAgent) buildDynamicSystemPrompt() string { + // Try to build the prompt, but never crash. + defer func() { + if r := recover(); r != nil { + slog.Error("buildDynamicSystemPrompt panicked, using fallback", "recover", r) + } + }() + + items, err := a.getTodoItems() + if err != nil { + slog.Warn("Failed to read todo list, using fallback", "error", err) + return "Dynamic state unavailable." + } + + var sb strings.Builder + for i, item := range items { + // Sanitize: strip non-printable chars + safe := sanitize(item.Text) + sb.WriteString(fmt.Sprintf("%d. %s\n", i+1, safe)) + } + + result := sb.String() + // Truncate if too large + maxLen := 2000 + if len(result) > maxLen { + result = result[:maxLen] + "\n[truncated]" + } + + return result +} + +func sanitize(s string) string { + // Strip non-printable characters except newlines and tabs + var out []rune + for _, r := range s { + if unicode.IsPrint(r) || r == '\n' || r == '\t' { + out = append(out, r) + } + } + return string(out) +} +``` + +This ensures the `PrepareStep` pipeline never fails due to corrupted state, and the model always receives a valid, bounded system prompt. + +## Why this approach + +1. **Uses existing fantasy API** — No need to fork or shim the library. The `PrepareStep` function already exists and supports dynamic system prompts. + +2. **Minimal code changes** — Remove 10 lines of user-message injection, add ~20 lines of system prompt building. + +3. **Extensible** — Future dynamic state (actual todo list items, goal state, etc.) can be added to `buildDynamicSystemPrompt()` without changing the conversation history. + +4. **Proper separation** — System instructions go in the system message, conversation goes in user/assistant messages. + +## What we're NOT doing + +- **No turn markers** — The model doesn't need explicit ordering signals. The API format provides this. +- **No sequence numbers** — Adding ordering to messages is unnecessary technical debt. +- **No DB migration** — The messages table doesn't need a sequence column for this fix. + +## Testing + +- **Unit tests**: Verify that `buildDynamicSystemPrompt()` returns the expected content +- **Integration tests**: Verify that the model responds to the latest user message in multi-turn conversations +- **Regression tests**: Ensure existing behavior (todo list, goal continuation) still works + +## Related work + +- **Loop detection fixes** (`internal/agent/loop_detection.go`): These address repeated reasoning/tool calls within a turn, not cross-turn ordering.
