# Phase 07 Plan 02: Auto-Continue Evaluator Summary

**MiniMax-based session evaluation returning CONTINUE/SWEEP/REDIRECT/DONE with plan file discovery and 5-step sweep pipeline**

## Performance

- **Duration:** 2 min
- **Started:** 2026-03-26T17:34:44Z
- **Completed:** 2026-03-26T17:36:50Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments

- AutoContinueEvaluator evaluates transcripts via MiniMax API, parsing response into ContinueDecision enum
- Plan file discovery scans transcript text with regex for .claude/plans/_.md and .planning/phases/_/PLAN.md references
- SWEEP mode builds a 5-step review pipeline prompt (verify, diff audit, plan check, integration, summary)
- NotificationWatcher callback wired into main.swift: parses notification JSON, triggers evaluation, sends Telegram notification
- Shared MiniMaxClient between SummaryEngine and AutoContinueEvaluator (single circuit breaker)

## Task Commits

Each task was committed atomically:

1. **Task 1: Create AutoContinue.swift with MiniMax evaluation and plan discovery** - `31e66ab2` (feat)
2. **Task 2: Wire NotificationWatcher and AutoContinueEvaluator into main.swift** - `b4ffab21` (feat)

## Files Created/Modified

- `plugins/claude-tts-companion/Sources/claude-tts-companion/AutoContinue.swift` - ContinueDecision enum, AutoContinueEvaluator with evaluate(), discoverPlanFiles(), buildSweepPrompt()
- `plugins/claude-tts-companion/Sources/claude-tts-companion/main.swift` - Shared MiniMaxClient, NotificationWatcher callback, entriesToTurns helper, strong references, SIGTERM cleanup

## Decisions Made

- Shared MiniMaxClient created externally in main.swift and injected into both SummaryEngine and AutoContinueEvaluator (single circuit breaker)
- NSRegularExpression used for plan file discovery with two patterns covering both .claude/plans and .planning/phases paths
- Default to DONE on any evaluation error to avoid runaway auto-continue loops
- Fuzzy decision parsing: if exact match fails, searches for known decision words anywhere in the response

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## User Setup Required

None - no external service configuration required (uses existing MINIMAX_API_KEY from environment).

## Known Stubs

None - all functionality is wired and operational.

## Next Phase Readiness

- Phase 07 (file-watching-auto-continue) is now complete with both plans done
- NotificationWatcher + AutoContinueEvaluator + Telegram notification pipeline fully integrated
- Ready for Phase 08 (HTTP control API) which can expose auto-continue status and settings
