Conventional Commit Workflow

When To Use

  • Generating conventional commit messages from staged changes

When NOT To Use

  • Full PR preparation: use sanctum:pr-prep
  • Amending existing commits: use git directly

Steps

  1. Gather context (run in parallel):

    • git status -sb
    • git diff --cached --stat
    • git diff --cached
    • git log --oneline -5
    • When sem is available (see leyline:sem-integration): sem diff --staged --json for entity-level changes

    If nothing is staged, tell the user and stop.

    When sem output is available, use entity names (function, class, method) in the commit subject and body instead of parsing raw diff hunks. For example, "add function validate_webhook_url" instead of "add validation logic to notify.py".

  2. Classify: Pick type (feat, fix, docs, refactor, test, chore, style, perf, ci) and optional scope.

  3. Draft the message:

    • Subject: <type>(<scope>): <imperative summary> (50 chars max)
    • Body: What and why, wrapped at 72 chars
    • Footer: BREAKING CHANGE or issue refs

  4. Slop check: reject these words and replace with plain alternatives:

    Reject Use instead
    leverage, utilize use
    seamless smooth
    comprehensive complete
    robust solid
    facilitate enable
    streamline simplify
    optimize improve
    delve explore
    multifaceted varied
    pivotal key
    intricate detailed

    Also reject: "it's worth noting", "at its core", "in essence", "a testament to"

4a. Character-level slop check: load shared/output-hygiene.md (Contract A) and strip these markers. Inline fallback if that module is absent:

Marker Replace with
"+" as a prose conjunction and (keep + in versions/code)
em-dash — colon, period, comma, or rewrite
-- as prose punctuation colon or rewrite
arrows -> / → as connectors to / into
smart quotes “ ” ‘ ’ straight " and '

4b. Subject-matter check (Contract B): describe the change by its reader-facing effect. Name neither the AI origin nor the specific marker removed. Do NOT write remove AI slop, de-slop, AI-generated content, AI phrasing, replace em-dashes, or remove smart quotes. Test: if the subject only makes sense as "I cleaned up AI output", rewrite it. For example docs: clarify the setup section, not style: replace em-dashes with colons.

  1. Write to ./commit_msg.txt and preview.

Rules

  • NEVER use git commit --no-verify or -n
  • Write for humans, not to impress
  • If pre-commit hooks fail, fix the issues
