This error originates from the OpenAI API, which strictly requires the system message to be the first element in the conversation messages array. + +The current interruption flow in `src/tui/app.js` uses an AbortController to signal tool interruption. The `handleInterrupt()` function signals the abort controller and awaits the dispatch promise. The try/catch around dispatchProvider calls handles AbortError gracefully but allows other errors (like the 400) to fall through to an unrecoverable error display. + +The root cause is that when a tool is interrupted, the conversation state may be left in an inconsistent state — for example, a tool result message may have been partially added to the conversation array before the system message, or the conversation array may have been corrupted during the abort process. Subsequent API calls then fail because the system message is no longer first. + +## Goals / Non-Goals + +**Goals:** +- Ensure conversation state is valid (system message first) after any interruption +- Gracefully handle non-AbortError errors that occur during active interruption +- Allow the user to continue the conversation normally after an interruption +- Add spec requirement for graceful interruption error handling + +**Non-Goals:** +- Changes to the TUI interrupt UI/UX (escape key behavior, visual feedback) +- Changes to the AbortController mechanism itself +- Changes to LLM provider configuration or API keys +- Conversation checkpoint persistence (already covered by existing spec) + +## Decisions + +### Decision 1: Use an `isInterrupting` state flag +**Choice:** Add an `isInterrupting` boolean flag to track when an interruption is in progress. +**Rationale:** This allows the error handler to distinguish between a normal error and an error that occurred during interruption. Without this flag, any error during tool execution would be indistinguishable from an interruption error. +**Alternatives considered:** +- Check if the error is an AbortError — but the 400 error is not an AbortError, it's a regular error from the API +- Use a try/catch around the entire interruption flow — but this would mask real errors that occur after interruption + +### Decision 2: Reset conversation state on interruption +**Choice:** When an interruption occurs, reset the conversation to a clean state (system message + any messages that were fully completed before the interrupted tool). +**Rationale:** This is safer than trying to partially roll back the conversation. The interrupted tool's result is incomplete and should not be preserved. +**Alternatives considered:** +- Reorder messages to ensure system message is first — but this doesn't address the root cause and could leave other inconsistencies +- Clear the entire conversation — too aggressive, loses valid conversation history + +### Decision 3: Catch errors during interruption in the outer try/catch +**Choice:** In the try/catch around dispatchProvider calls, check the `isInterrupting` flag and handle errors gracefully if true. +**Rationale:** This ensures that errors occurring during the interruption window are not displayed as unrecoverable errors. +**Alternatives considered:** +- Add a separate try/catch around the interruption handling — but this would duplicate error handling logic +- Let the error propagate and handle it at a higher level — but there is no higher level that knows about interruption state + +## Risks / Trade-offs + +### Risk: Race condition with rapid interruptions +**Mitigation:** The `isInterrupting` flag is set before the abort signal is sent and cleared after the dispatch promise resolves. Rapid interruptions will be serialized by the promise chain. + +### Risk: Conversation state reset loses valid messages +**Mitigation:** Only messages that were fully completed before the interrupted tool are preserved. Partial tool results are discarded, which is the correct behavior. + +### Risk: New error handling masks real bugs +**Mitigation:** The `isInterrupting` flag ensures that only errors during active interruption are handled gracefully. Errors that occur after interruption completes will still be displayed normally. + +## Migration Plan + +This is a bug fix with no migration required. The changes are: +1. Add `isInterrupting` flag to the TUI app state +2. Modify `handleInterrupt()` to set the flag and reset conversation state +3. Modify the try/catch around dispatchProvider to check the flag +4.

behavior) +### Requirement: Graceful Error Handling During Tool Interruption +The system SHALL catch and handle non-AbortError errors that occur during an active tool interruption without displaying them as unrecoverable errors. When an interruption is in progress, any error from the dispatch provider SHALL be treated as a graceful interruption and the conversation SHALL be reset to a valid state. + +#### Scenario: User interrupts tool execution +- **WHEN** the user interrupts a tool execution (e.g., via escape key or interrupt action) +- **THEN** the system sets an `isInterrupting` flag and signals the abort controller + +#### Scenario: Non-AbortError occurs during interruption +- **WHEN** a non-AbortError (e.g., 400 API error) occurs while `isInterrupting` is true +- **THEN** the system catches the error gracefully, resets the conversation state, and allows the user to continue the conversation + +#### Scenario: Conversation state is reset after interruption +- **WHEN** an interruption completes +- **THEN** the conversation is reset to a valid state with the system message as the first element + +#### Scenario: TUI shows graceful message instead of error during interruption +- **WHEN** an error occurs while `isInterrupting` is true +- **THEN** the TUI displays a graceful interruption message (e.g., "Interrupted") instead of an error message + +#### Scenario: Normal errors after interruption are not suppressed +- **WHEN** an error occurs after `isInterrupting` is false (interruption completed) +- **THEN** the system handles the error according to existing error handling logic (no change to current behavior) +
