commit-message

commit-message is a cursor rule for Cursor from danielvm-git/bigpowers. It costs 68 tokens per session (1,957 once invoked), scanned A, original, MIT.

Reviews working-tree changes, then drafts a Conventional Commits title/body and states the semantic-release version bump a single such commit would imply. Also notes which defensive-code categories were touched. Use when the user wants to commit recent work, prepare a Conventional Commits message, or asks for…

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-message 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 today.

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.

Commit Message

HARD GATEHARD GATE — Commits must follow Conventional Commits spec (type(scope): description). Do NOT use vague messages like 'fix' or 'updates.' The message must explain the 'why,' not the 'what.'

Modes

  • Default: standard Conventional Commits message
  • --fix-type: Forces type=fix. Use when commit type is unambiguous.

What "last chat" means

  • Primary source of truth: Read state.yaml vcs.kind. Git uses git status, git diff, and git diff --cached; Jujutsu uses jj status, jj diff, and jj log -r @. Run in the repo root.
  • Context: use the current conversation to summarize intent and to spot breaking API/behavior changes that diff alone may not show.
  • If the user tracks a session baseline (e.g. branch, tag, or git stash create at start), you may git diff <baseline>..HEAD plus uncommitted diffs; otherwise use only the index and working tree.

Quick workflow

  1. Inventory — List changed paths; group by feature vs chore vs docs vs test-only.
  2. Decide commit shape — One atomic commit is ideal. If the diff mixes unrelated concerns, recommend multiple commits (each with its own type/scope) before suggesting one message.
  3. Classify for semantic releasefix → patch, feat → minor, breaking → major.
  4. Write the messagetype(optional-scope)!: description (see REFERENCE.md). Use ! or a BREAKING CHANGE: footer when behavior contracts change.
  5. Note defensive-code categories touched — from CONVENTIONS.md: Rate limit | Retry with backoff | Circuit breaker | Timeout | Graceful degradation
  6. Note fix-ratio contribution — Each fix: commit counts toward metrics.commit_ratio.fix in specs/state.yaml. After release-branch, session-state recalculates the ratio automatically. A high fix rate (>30%) triggers a deploy + smoke-test suggestion.
  7. Deliver — Output:
    • Proposed full commit message (title + optional body + footers).
    • Release bump this commit would drive: patch | minor | major | none.
    • Optional native command: Git git commit -m; Jujutsu jj commit -m. Never omit -m or run destructive commands unless asked.

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.
