# Phase 25 Plan 07: Agent-Generated File Support and Placeholder Tracking Summary
|
|
|
|
**PLACEHOLDERS.md manifest service with addEntry/replaceEntry and POST /files/:fileId/replace endpoint wiring agent-generated uploads to per-project markdown manifests**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** ~10 min
|
|
- **Started:** 2026-04-02T00:09:00Z
|
|
- **Completed:** 2026-04-02T00:12:49Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 5
|
|
|
|
## Accomplishments
|
|
- Created `placeholder-service.ts` with full PLACEHOLDERS.md markdown table management (addEntry, replaceEntry, listEntries)
|
|
- Added `markAsPlaceholder` method to `chatFileService` for DB-level placeholder categorization
|
|
- Wired agent_generated + project-scoped uploads to automatically update PLACEHOLDERS.md
|
|
- Added `POST /files/:fileId/replace` endpoint that updates manifest and creates DB reference chain
|
|
- Marked FILE-08 and FILE-11 Complete in REQUIREMENTS.md
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Create placeholderService and add markAsPlaceholder method** - `0a80659c` (feat)
|
|
2. **Task 2: Add placeholder and agent-generated file routes** - `2a4037ca` (feat)
|
|
|
|
## Files Created/Modified
|
|
- `server/src/services/placeholder-service.ts` - PLACEHOLDERS.md manifest management service (161 lines)
|
|
- `server/src/services/chat-files.ts` - Added markAsPlaceholder method
|
|
- `server/src/routes/chat-files.ts` - Added phSvc import, agent_generated tracking, /replace endpoint
|
|
- `packages/shared/src/types/chat.ts` - Added ChatPlaceholderEntry interface
|
|
- `packages/shared/src/index.ts` - Exported ChatPlaceholderEntry
|
|
- `.planning/REQUIREMENTS.md` - Marked FILE-08 and FILE-11 Complete
|
|
|
|
## Decisions Made
|
|
- Used regex row parser (`/^\|\s*(.+?)\s*\|\s*(.+?)\s*\|\s*(.+?)\s*\|$/`) to parse markdown tables — no external markdown deps needed
|
|
- `addEntry` is fire-and-forget (non-blocking) to avoid blocking upload response
|
|
- `replaceEntry` is awaited in the replace endpoint for manifest consistency before response
|
|
- Used `resolveDefaultStorageDir()` for project dir base path, consistent with 25-06 storageDir pattern
|
|
- `git-file-service.ts` not present on this branch (in 25-06 worktree); storageDir import added here for placeholder path only
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
- `git-file-service.ts` not present on current branch (it's in the 25-06 worktree). Per the important_context note, proceeded with placeholder-service implementation and imported `resolveDefaultStorageDir` directly for the project path computation. No blocking impact.
|
|
|
|
## Next Phase Readiness
|
|
- PLACEHOLDERS.md manifest management complete; any agent that uploads with source=agent_generated and projectId will auto-track
|
|
- Replace endpoint ready for agent workflows that upgrade placeholder assets to final outputs
|
|
- FILE-08 and FILE-11 marked complete
