commit-planner

A read-only tool for dividing changes in a Git working tree into separate Conventional Commits, a shared format for clear commit messages.

In plain words
What is it for?
Use it to inspect uncommitted files, group them by concern, and prepare a proposed commit plan for later approval.
Why use it?
It prevents unrelated edits, such as documentation and source changes, from being bundled into one commit and does not stage or change files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

commit-planner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (inventory.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.

commit-planner — single-concern commit splitting

A dirty tree with mixed concerns (a hook fix, a docs edit, an unrelated config tweak) should not land as one commit. This skill proposes a split into single-concern Conventional Commits groups and stops. Execution stays with /commit (Phase 11) under the normal consent gates — one approved group at a time.

This skill is a generator, not a workflow phase. It enters no Track Guard ordering, blocks nothing, and writes nothing outside its report. It is read-only until the user approves the plan, and even then it only hands the approved grouping to the normal commit path.

Method

1. Inventory the dirty tree

Run git status --porcelain and collect {path, status} entries (untracked included). Do not stage anything.

2. Group deterministically

Feed the entries to the helper:

node .claude/skills/commit-planner/inventory.mjs group --json   # wraps inventory.mjs -> groupDirtyTree

groupDirtyTree(entries) is pure and deterministic — no fs, no git, no clock; the same entries (in any order) produce the same groups. Each group carries:

  • type — the Conventional Commit type the group's paths imply (docs, test, chore, feat/fix candidates surface as src-typed groups for main context to refine).
  • scope — a path-derived scope hint (top-level dir or hook/skill slug), or null.
  • paths — the group's member paths. Every input path appears in exactly one group (partition).

Pairing rule: a source file and its paired test (conventional mapping, e.g. .claude/hooks/foo_guard.mjstests/foo-guard.test.mjs) always land in the SAME group — a commit that changes behavior carries its test.

3. Refine in main context

The helper's grouping is mechanical. Main context (Article II — decisions live here) refines it: merge groups that are one logical change, pick the final type(scope): subject per group, order the groups (dependencies first), and flag any group that intersects governance surfaces (CLAUDE.md, docs/init/**, .claude/hooks/**) for extra review.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

commit-planner is a skill published in the GitHub repository friedbotstudio/baseline (11 stars, last pushed 6d ago), licensed Apache-2.0. It adds 116 tokens to every session and 859 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
