package.json

Fixed imageModel name from gemini-3.1-flash-preview-image to gemini-3.1-flash-image-preview

Script skips already-generated assets for re-runnability

2-second delay between API calls to avoid rate limiting

Build scripts use tsx for Node.js TypeScript execution

Asset generation reads config from public/config.json via fs.readFileSync

Character avatars use character sheets as reference images for visual consistency

Phase 02 Plan 03: Asset Generation Summary

IndexedDB store accessors + Gemini-powered build script generating 4 character sheets, 4 avatars, and 1 style reference image

Performance

Duration: 6 min
Started: 2026-03-29T10:04:23Z
Completed: 2026-03-29T10:10:30Z
Tasks: 2
Files modified: 12

Accomplishments

Added 6 IndexedDB accessor methods (save/get for companionAssets, styleReference, forestElements)
Created build script that calls Gemini API to generate character sheets with 3 views (front, side, face) and matching avatars
Generated all 9 PNG assets: 4 character sheets, 4 avatars, 1 style reference (initial forest scene)
Script is re-runnable (skips existing assets) with graceful error handling

Task Commits

Each task was committed atomically:

Task 1: Add IndexedDB accessor methods for remaining stores - a242ce1 (feat)
Task 2: Build script for asset generation + run it - 1fa7d52 (feat)

Files Created/Modified

src/storage/db.ts - Added saveCompanionAssets, getCompanionAssets, saveStyleReference, getStyleReference, saveForestElement, getForestElements
scripts/generate-assets.ts - Build script reading config.json, calling Gemini API, saving 9 PNGs
package.json - Added tsx devDependency and generate-assets npm script
src/assets/companions/*/character-sheet.png - Character sheets (3-view: front, side, face) for all 4 companions
src/assets/companions/*/avatar.png - Portrait avatars for all 4 companions
src/assets/style-reference/initial-forest-scene.png - Watercolor forest clearing style reference

Decisions Made

Fixed imageModel name in config.json (gemini-3.1-flash-preview-image was 404, corrected to gemini-3.1-flash-image-preview)
Script skips already-generated assets (checks file existence + size > 1KB) for idempotent re-runs
Added 2-second delay between API calls to respect rate limits
Avatar generation uses character sheet as reference image for visual consistency

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed incorrect image model name in config.json

Found during: Task 2 (running generate-assets script)
Issue: Model name gemini-3.1-flash-preview-image returns 404; correct name is gemini-3.1-flash-image-preview
Fix: Updated public/config.json imageModel field
Files modified: public/config.json (gitignored)
Verification: API returns 200 and generates images successfully
Committed in: Not committed (file is gitignored), but documented for user awareness

Total deviations: 1 auto-fixed (1 bug) Impact on plan: Essential fix for API connectivity. No scope creep.

Issues Encountered

Gemini API returned 404 for the configured imageModel name. Resolved by listing available models and correcting the name.

User Setup Required

None - Gemini API key already configured in public/config.json from Phase 1 setup.

Next Phase Readiness

All character assets generated and committed to git
IndexedDB store accessors ready for runtime use
Style reference image available for consistent art direction in future forest element generation
Ready for Plan 04 (companion integration) and Plan 05 (forest reward pipeline)

Self-Check: PASSED

All 10 created files verified present. Both task commits (a242ce1, 1fa7d52) verified in git log.
