Git Commit

Create a commit with a conventional commit message based on staged changes. Automatically stages all changes and analyzes the diff to generate an appropriate commit message.

Workflow

Execute these steps in order.

Step 1: Check Repository State

Check for changes to commit:

git status --porcelain

• If output is empty, report: "Nothing to commit. Working directory is clean." and stop.
• If changes exist, continue to Step 2.

Step 2: Stage All Changes

Run:

git add .

Report: "Staged all changes."

Step 3: Analyze Changes

View the staged diff to understand what changed:

git diff --cached --stat

git diff --cached

Analyze the diff to determine:

• The type of change (feat, fix, docs, refactor, etc.)
• The scope (optional, based on affected files/modules)
• A concise description of what changed

Step 4: Construct Commit Message

Build a conventional commit message following this format:

<type>(<optional-scope>): <description>

[optional body]

Types:

• feat

  - New feature

• fix

  - Bug fix

• docs

  - Documentation only

• style

  - Formatting, no code change

• refactor

  - Code restructuring without behavior change

• test

  - Adding or updating tests

• chore

  - Maintenance tasks

• build

  - Build system or dependencies

• ci

  - CI configuration

• perf

  - Performance improvement

Rules:

• Use imperative mood ("add" not "added")
• Use lowercase
• No trailing period
• Keep description under 72 characters
• Add a body only for complex changes or breaking changes
• Do NOT add co-author, attribution, or "Generated with" lines

Step 5: Create Commit

Run:

git commit -m "$(cat <<'EOF'
<commit message here>
EOF
)"

Step 6: Handle Result

On success:

• Report the commit hash: "Committed: {short_hash} - {message}"

On pre-commit hook failure:

• Report: "Pre-commit hook failed. The commit was NOT created."
• Explain what the hook reported
• Instruct: "Fix the issues above and run the commit command again. Do NOT use --amend as that would modify the previous commit."

Error Recovery

If the commit fails:

• Hook failure: Fix the reported issues, then stage and commit again (do NOT amend)
• Unstage changes:

  git reset HEAD

  to unstage without losing changes

Notes

• This command stages ALL changes including untracked files
• Pre-commit hooks run automatically; their failures mean no commit was created
• Always create a NEW commit after hook failure, never amend the previous commit

Integration Notes

Required Capabilities

git status

git add

git diff

git commit

git reset

External Dependencies

• git CLI must be available on the system PATH
• Repository must be initialized (

  git init

  or cloned)

Platform Considerations

• The heredoc syntax for commit messages (

  cat <<'EOF'

  ) assumes a POSIX-compatible shell (bash, zsh, sh)
• Pre-commit hooks are repository-specific; behavior varies by project configuration
