One thing to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

What its author says it does

Copied from the file, not written here

Detects stale project plans and suggests session commands. Triggers on: sync plan, update plan, check status, plan is stale, track progress, project planning.

The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

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docs/PLAN.md "In Progress" section outdated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
