provides:

- HookEvent struct parsing Claude Code hook JSON
|
|
- processHookEvent mapping 4 event types to State+WaitType
|
|
- UpdateFromHook with auto-create and WaitingSince transitions
|
|
- handleHook HTTP handler with POST validation and body size limit
|
|
- SessionInfo.WaitType field for wait type discrimination

key-decisions:
|
|
- "WaitType omitempty: champ vide omis du JSON pour compatibilite avec les clients existants"
|
|
- "UpdateFromHook separe de Update: les hooks ne connaissent pas PID/GitBranch/Preview, donc methode dediee qui ne touche que les champs connus"
|
|
|
|
patterns-established:
|
|
- "Hook event mapping: switch sur HookEventName puis NotificationType pour determiner State+WaitType"
|
|
- "HTTP handler pattern: method check, MaxBytesReader, JSON decode, process, 200 OK"

# Phase 03 Plan 01: Hook Event Processing Summary
|
|
|
|
**HookEvent parsing, event-to-state mapping (Notification/Stop/PostToolUse/PreToolUse), UpdateFromHook avec auto-create, et HTTP handler POST /hook avec validation**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 3 min
|
|
- **Started:** 2026-03-23T18:38:37Z
|
|
- **Completed:** 2026-03-23T18:41:45Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 4
|
|
|
|
## Accomplishments
|
|
- HookEvent struct couvre tous les champs du payload Claude Code hooks
|
|
- processHookEvent mappe les 4 types d'events (Notification, Stop, PostToolUse, PreToolUse) vers State+WaitType
|
|
- UpdateFromHook gere les sessions inconnues et les transitions WaitingSince
|
|
- handleHook HTTP handler valide method, body size (64KB), et JSON
|
|
- 16 tests couvrent tous les cas
|
|
|
|
## Task Commits
|
|
|
|
1. **Task 1: HookEvent struct, processHookEvent mapping, UpdateFromHook, WaitType** - `e1b176c` (feat)
|
|
2. **Task 2: HTTP handler POST /hook avec validation et protection** - `5bec943` (feat)
|
|
|
|
## Files Created/Modified
|
|
- `hook.go` - HookEvent struct, handleHook HTTP handler, processHookEvent, UpdateFromHook
|
|
- `hook_test.go` - 16 tests (12 mapping + 4 HTTP handler)
|
|
- `protocol.go` - SessionInfo enrichi avec WaitType
|
|
- `protocol_test.go` - Test serialisation JSON de WaitType
|
|
|
|
## Decisions Made
|
|
- WaitType omitempty : le champ vide est omis du JSON pour ne pas casser les clients existants qui ignorent ce champ
|
|
- UpdateFromHook est une methode separee de Update car les hooks ne connaissent pas PID, GitBranch, Preview, Workspace, Label
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- hook.go fournit toute la logique de traitement. Le plan 03-02 peut integrer le HTTP server dans le Daemon (startHookServer, hookPort, poll slowdown).
|
|
- handleHook est pret a etre monte sur un http.ServeMux.
