Project Planner Skill Skill

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.md exists 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docs/PLAN.md "In Progress" section outdated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
/sync reads state, /save writes state
Single source of truth: docs/PLAN.md
