Agent Skills: Post-Commit Skill

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). Add a new entry at the top of CHANGELOG.md (create it with a # Changelog heading first if missing). Load references/changelog-templates.md for the exact entry format and references/changelog-type-mapping.md for the commit-type prefix.

Step S2: Commit CHANGELOG

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

STOP. Output summary. No tag here — it is created POST-MERGE by the commit command's Step 8 (or locally-only in LOCAL/DEGRADED mode when no remote/gh is available — see the Step 7 decision tree in commands/commit.md). Load references/tag-timing.md for the full post-merge rationale and the standalone-use exception.

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: read plugins/{name}/.claude-plugin/plugin.json, increment PATCH (X.Y.Z → X.Y.(Z+1)), write it back. Load references/plugin-version-bump.md for the marketplace.json type-detection rule (plugins[] vs core[]).

Step M3: Bump Suite Version + Recompute README Badges

Read metadata.version from .claude-plugin/marketplace.json, increment PATCH (X.Y.Z → X.Y.(Z+1)), write it back.

Then recompute EVERY shields.io badge in README.md from the filesystem — never hand-maintain counts (they drift). Load references/badge-recompute.md for the exact count commands and sed replacements (version/plugins/agents/skills tokens).

Step M3.5: Documentation Parity

For any plugin added in this commit, create its docs page and link it. Doc filenames are abbreviated (e.g. dir nextjs-expert → docs/plugins/nextjs.md), so match existing naming in docs/plugins/, not the raw dir. Load references/plugin-docs-parity.md for the detection command and the full per-plugin checklist.

Step M4: Update CHANGELOG

Add a new entry at the top of CHANGELOG.md, using the new suite version X.Y.Z from Step M3 and (plugin-name X.Y.Z) for each bumped plugin. Load references/changelog-templates.md for the exact entry format and references/changelog-type-mapping.md for the commit-type prefix.

Step M5: Commit the Bump

Stage all modified files:

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

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. No tag here — same post-merge rationale as Step S2. Load references/tag-timing.md for details.

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

CHANGELOG Type Mapping

See references/changelog-type-mapping.md for the commit-type → CHANGELOG-prefix table used in Step S1 and Step M4 entries.
