Post-Commit Skill

Universal post-commit actions after a successful code commit.

Step 1: Read Last Commit

git log --format='%s' -1

Save the commit message for CHANGELOG entry.

Step 2: Detect Repo Type

Check if .claude-plugin/marketplace.json exists in the repo root.

• EXISTS → Follow Marketplace Path (Steps M1–M5)
• DOES NOT EXIST → Follow Standard Path (Steps S1–S2)

---

Standard Path (any repo without marketplace.json)

Step S1: Update CHANGELOG

Read the latest git tag to determine current version:

git describe --tags --abbrev=0 2>/dev/null || echo "v0.0.0"

Increment PATCH: X.Y.Z → X.Y.(Z+1).

If CHANGELOG.md does not exist, create it with # Changelog heading.

Add a new entry at the top (after the # Changelog heading):

## [X.Y.Z] - DD-MM-YYYY

- commit message from Step 1

Step S2: Git Tag

git add CHANGELOG.md
git commit -m "$(cat <<'EOF'
chore: update CHANGELOG to X.Y.Z
EOF
)"
git tag vX.Y.Z

STOP. Output summary and ask user if they want to push the tag.

Marketplace Path (repo with .claude-plugin/marketplace.json)

Step M1: Detect Modified Plugins

git diff --name-only HEAD~1 | grep '^plugins/' | cut -d/ -f2 | sort -u

If no plugins modified → Skip to Step M3 (still bump suite version).

Skip directories without .claude-plugin/plugin.json.

Step M2: Bump Plugin Versions

For each modified plugin detected in Step M1:

1. Read plugins/{name}/.claude-plugin/plugin.json
2. Increment PATCH version: X.Y.Z → X.Y.(Z+1)
3. Write the new version back to plugin.json

Then determine plugin type from marketplace.json:

• In plugins[] array → Also update matching version field in marketplace.json
• In core[] array → Only bump plugin.json (core entries have no version field)

Step M3: Bump Suite Version

Read metadata.version from .claude-plugin/marketplace.json.

Increment PATCH: X.Y.Z → X.Y.(Z+1).

Write the new suite version back to marketplace.json → metadata.version.

If README.md contains a shields.io version badge, update it to match the new version:

Replace version-vOLD_VERSION- with version-vNEW_VERSION- in the badge URL.

Step M4: Update CHANGELOG

Add a new entry at the top of CHANGELOG.md (after the # Changelog heading):

## [X.Y.Z] - DD-MM-YYYY

- type(plugin-name): description from the code commit message

Where X.Y.Z is the new suite version from Step M3.

Include (plugin-name X.Y.Z) in each line for bumped plugins.

Step M5: Commit, Tag, and Push

Stage all modified files:

git add CHANGELOG.md README.md .claude-plugin/marketplace.json plugins/*/.claude-plugin/plugin.json

Commit with HEREDOC format:

git commit -m "$(cat <<'EOF'
chore: bump marketplace and CHANGELOG to X.Y.Z
EOF
)"

This MUST be a separate commit from the code changes. Never combine.

Then tag and push:

git tag vX.Y.Z
git push origin vX.Y.Z

Only tag the bump commit. Never tag code commits.

Version Bump Rules

• ALL commit types trigger PATCH bump only
• MINOR/MAJOR bumps are manual user decisions, never automatic
• The bump commit is always SEPARATE from code changes
