Initialize the BACKLOG/ directory structure for ticket tracking. ## Steps 1. **Check** if `BACKLOG/` already exists. If it does, inform the user and stop. 2. **Create the directory structure:** ``` BACKLOG/ ├── BUGS/{PENDING,DONE}/ ├── FEATURES/{PENDING,DONE}/ ├── IMPROVEMENTS/{PENDING,DONE}/ └── _templates/ ``` 3. **Create `BACKLOG/_templates/ticket.md`** — copy from `~/.claude/templates/backlog/ticket.md` if it exists, otherwise create it with this content: ```markdown # [TYPE]-XXX: Titre court **Type:** Bug | Feature | Improvement **Statut:** A faire | En cours | Bloque | Fait **Priorite:** Critique | Haute | Moyenne | Basse **Complexite:** XS | S | M | L | XL **Tags:** [libres, separes par virgule] **Depends on:** none **Blocked by:** — **Date creation:** YYYY-MM-DD --- ## Description [Description claire] ## Fichiers concernes - `path/to/file` ## Criteres d'acceptation - [ ] Critere 1 ## Tests de validation - [ ] Test 1 ``` 4. **Create `BACKLOG/INDEX.md`** with just the header (it will be fully generated by `/backlog-status`): ```markdown # BACKLOG — [project basename] _Run `/backlog-status` to populate this file._ ``` 5. **Display** the created structure to confirm.
