# Phase 02 Plan 04: Companion Text Module Summary
|
||
|
|
|
||
|
|
**Companion text module with 3 exported functions (getGreeting, getLetterIntro, getForestComment) using Gemini API-first strategy with curated German fallbacks**
|
||
|
|
|
||
|
|
## Performance
|
||
|
|
|
||
|
|
- **Duration:** 1 min
|
||
|
|
- **Started:** 2026-03-29T10:04:46Z
|
||
|
|
- **Completed:** 2026-03-29T10:06:01Z
|
||
|
|
- **Tasks:** 1 (TDD: RED + GREEN)
|
||
|
|
- **Files modified:** 2
|
||
|
|
|
||
|
|
## Accomplishments
|
||
|
|
- Companion text module with API-first fallback strategy for all 3 dialogue types
|
||
|
|
- System prompts enforce max 25 words, simple German, no performance praise
|
||
|
|
- 13 tests covering API success, API failure, no config, and rate-limited paths
|
||
|
|
|
||
|
|
## Task Commits
|
||
|
|
|
||
|
|
Each task was committed atomically:
|
||
|
|
|
||
|
|
1. **Task 1 (RED): Companion test suite** - `6fba02c` (test)
|
||
|
|
2. **Task 1 (GREEN): Companion text module implementation** - `4b4aa8e` (feat)
|
||
|
|
|
||
|
|
_TDD task: test file committed first (RED), then implementation (GREEN)._
|
||
|
|
|
||
|
|
## Files Created/Modified
|
||
|
|
- `src/companion/companion.ts` - Companion text module with getGreeting, getLetterIntro, getForestComment
|
||
|
|
- `src/companion/companion.test.ts` - 13 tests covering all fallback paths and API integration
|
||
|
|
|
||
|
|
## Decisions Made
|
||
|
|
- Prompt templates use ue/oe/ae transliteration consistent with existing codebase convention
|
||
|
|
- Each function independently checks config and rate limits rather than using a shared wrapper, keeping the code straightforward and readable
|
||
|
|
|
||
|
|
## Deviations from Plan
|
||
|
|
|
||
|
|
None - plan executed exactly as written.
|
||
|
|
|
||
|
|
## Issues Encountered
|
||
|
|
None
|
||
|
|
|
||
|
|
## User Setup Required
|
||
|
|
None - no external service configuration required.
|
||
|
|
|
||
|
|
## Next Phase Readiness
|
||
|
|
- Companion text module ready for integration into exercise flow
|
||
|
|
- All 3 functions exported and tested, ready for import by UI screens
|
||
|
|
- Depends on config.json with valid Gemini API key for AI-generated text; works without it via fallbacks
