name: git-commit-messages description: Format git commit messages correctly, avoiding HEREDOC syntax issues in favor of multiline strings

Git Commit Message Formatting

When to Use This Skill

Use this skill when creating git commits with the Bash tool, especially for commits with:

• Multi-line messages
• Body text or explanations
• Co-authored-by footers
• Claude Code attribution

Core Principle

Avoid HEREDOC syntax - Use -m with multiline strings instead.

Pattern to Follow

✅ DO - Use multiline string with -m

Copygit commit -m "feat(github): add github plugin

This adds comprehensive GitHub workflow support including
commands for PR management and review workflows.

Key points:

• Single -m flag with entire message in quotes
• Newlines preserved within the quoted string
• No special syntax or escaping needed
• Works reliably across all environments

❌ DON'T - Use HEREDOC syntax

Copy# This FAILS in Claude Code's Bash tool
git commit -m "$(cat <<'EOF'
feat(github): add github plugin

This adds comprehensive GitHub workflow support.

EOF
)"

Why this fails:

• HEREDOC syntax has shell interpretation issues
• Fails in certain execution contexts
• More complex than necessary
• Unreliable across environments

Examples

Simple commit

Copygit commit -m "fix: resolve path configuration issue"

Commit with body

Copygit commit -m "feat: add progressive disclosure pattern

Skills now support references/ subdirectory for
detailed documentation that loads on-demand."

Commit with footer

Copygit commit -m "chore: update dependencies

Full conventional commit

Copygit commit -m "feat(tools): add git commit message skill

This skill teaches Claude to format git commit messages
using multiline strings instead of HEREDOC syntax, which
fails in certain shell environments.

The pattern uses a single -m flag with the entire message
in quotes, preserving newlines naturally.

Why It Matters

Using -m with multiline strings is:

• Reliable: Works consistently in all environments
• Simple: No complex shell syntax needed
• Portable: Standard git behavior
• Direct: Git handles newlines correctly

HEREDOC syntax causes issues because:

• Shell interpretation varies by environment
• Execution context in Claude Code differs from terminal
• Quote handling becomes complex
• Unnecessary complexity for the task

Quick Reference

Template for commits with Claude Code attribution:

Copygit commit -m "<type>[optional scope]: <description>

[optional body]

Remember:

• One -m flag
• Entire message in double quotes
• Newlines work naturally
• No HEREDOC needed
