“/project-planner”

Requirements

Pre-approved tools (allowed-tools): Read, Glob, TaskList, TaskCreate

What it can do on your machine

Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Read
- Glob
- TaskList
- TaskCreate
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/, which the agent can run.
Shell commands in SKILL.md call:
- git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Project Planner loads about 504 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 163 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~44
When it runs · the whole SKILL.md, loaded when a task matches: ~504

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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
