Project Planner Skill
Lightweight awareness layer for docs/PLAN.md. Detects when plans need attention and points to /save and /sync commands.
Purpose
This skill does NOT manage plans directly. It:
- Detects when
docs/PLAN.mdexists or is missing - Identifies stale plans (no recent updates vs git activity)
- Suggests appropriate session commands
All plan operations go through /save (persist) and /sync (restore/status).
Detection Logic
Plan Missing
No docs/PLAN.md found
-> Suggest: /save to create initial plan from conversation
Plan Stale
docs/PLAN.md last modified: 5 days ago
git log shows: 12 commits since then
-> Suggest: /sync --git to update from commits
Uncommitted Work
git status shows: 5 modified files
docs/PLAN.md "In Progress" section outdated
-> Suggest: /sync --status to review
Session Start
Resuming work on project with docs/PLAN.md
-> Suggest: /sync to restore state
Quick Reference
| Situation | Suggestion |
|---|---|
| No plan exists | /save after discussing goals |
| Plan is stale | /sync --git |
| Need to see plan | /sync --status |
| Update progress | /save "notes" |
| Start fresh | /save --archive |
Staleness Heuristics
A plan is considered stale when:
- Last modified > 3 days ago AND
- Git shows commits since last modification AND
- Commits relate to plan topics (feat:, fix:, refactor:)
A plan needs review when:
- Session just started
- Significant uncommitted changes exist
- User mentions progress or completion
Notes
- This skill only suggests, never modifies
/syncreads state,/savewrites state- Single source of truth:
docs/PLAN.md
