Commit Skill

Generate well-formatted commit messages and commit staged changes for AionHub.

Usage

• /commit - Generates a commit message based on staged changes
• /commit <advice> - Uses provided advice to guide commit message generation

Guidelines

• Only commit staged files - Never add files with git add. The user controls staging.
• Analyze all staged changes - Review both previously staged and newly added changes
• Follow commit message format - Use the project format shown below
• Match the project style - Check recent commits (git log) to match existing style

Format

<Type>[!](<scope>): <message title>

<bullet points summarizing changes>

[optional BREAKING CHANGE section if applicable]

Key convention: Type is always lowercase (e.g., feat, fix, chore, not Feat, Fix, Chore).

Examples

Basic commits

feat(extensions): add new ACP agent extension

- Added aion-extension.json manifest and install script
- Registered extension in build pipeline

fix(kits): resolve server startup crash on missing config

- Added fallback for undefined port in dev server
- Improved error message when config file is absent

refactor(build): use content-based SHA-256 for deterministic integrity

- Replaced timestamp-based hashing with file content hashing
- Ensures reproducible builds across environments

chore(extensions): promote claude, codex, goose from pending to extensions

- Moved directories from pending/ to extensions/
- Updated build script to include new entries

No scope (cross-cutting changes)

chore: add .gitignore and remove dist from tracking

- Created .gitignore with standard Node/dist patterns
- Removed previously tracked dist artifacts

Breaking change

refactor!(extensions): redesign manifest schema from v1 to v2

- Replaced flat fields with nested contributes block
- Updated all existing manifests to new format

BREAKING CHANGE: aion-extension.json schema v1 is no longer supported.

Rules

• Type: Always lowercase (feat, fix, chore, etc.), no period at end
• Title: Lowercase after colon, max 50 characters total
• Breaking changes: Use "!" after type/scope AND include "BREAKING CHANGE:" section
• Scope: Optional, lowercase, aligned with project directory/module name
• Body: Use bullet points, explain WHY not just WHAT
• Be specific: Avoid vague titles like "update" or "fix stuff"

Allowed Types

Type	Description
feat	New feature or extension
fix	Bug fix
chore	Maintenance (deps, config, file moves)
perf	Performance improvements
refactor	Code restructure (no behavior change)
docs	Documentation changes
test	Adding or refactoring tests
style	Code formatting (no logic change)
build	Changes to the build system or scripts
ci	Changes to CI/CD workflows

Common Scopes

Scope	When to use
extensions	Changes under extensions/ (manifests, installs)
kits	Changes under kits/ (server, fake agent, toolkits)
build	Build scripts under .github/scripts/
ci	CI workflows under .github/workflows/
docs	Documentation under docs/

Omit scope for cross-cutting changes that span multiple areas.

Workflow

1. Review changes in parallel:

   • Run git status (never use -uall flag)
   • Run git diff --cached (staged changes)
   • Run git diff (unstaged changes)
   • Run git log -5 --oneline to confirm current commit style

2. Draft commit message:

   • Summarize the nature of changes (new feature, bug fix, etc.)
   • Ensure message accurately reflects changes and purpose
   • Use lowercase type matching the project convention
   • Pick the most fitting scope from the table above
   • Focus on WHY rather than WHAT
   • Never commit files that likely contain secrets (.env, credentials.json, etc.)

3. Commit:

   • Create commit with proper message format
   • Always use HEREDOC for commit messages:

   git commit -m "$(cat <<'EOF'
   feat(extensions): descriptive title
   
   - Bullet point summary
   - Another change detail
   
   EOF
   )"
   

   • Verify with git status after commit

4. If pre-commit hook fails:

   • Fix the issue
   • Create a NEW commit (do not use --amend)
   • Never skip hooks unless explicitly requested

Important Notes

• Never push unless user explicitly requests it
• Never stage files without asking - Must ask the user for confirmation before running any git add command
• Never use interactive flags (-i) as they require user input
• No empty commits - If nothing is staged, inform the user instead
• Always use HEREDOC for commit messages to ensure proper formatting
• Never add Co-Authored-By - Do not append any Co-Authored-By trailer for any agent
• One commit per concern - If staged changes span multiple unrelated concerns, split into separate commits. Each commit should have a single, clear purpose
