​
Standard Workflow

  1. Make your changes
  2. Stage changes: 
    git add .
  3. Preview commit message: 
    forge commit --preview
  4. Commit if satisfied: 
    forge commit

​

# Preview the message
forge commit --preview

# If you want to edit it manually
git commit

​
AI Analysis

The AI analyzes:
  • Files changed
  • Lines added/removed
  • Code context
  • Commit patterns in your repository
  • Your custom text (if provided)
The generated message includes:
  • Concise summary line
  • Detailed description (when appropriate)
  • Relevant context about the changes

​
Best Practices

​
Use Preview Mode

Always preview first for important commits: 
forge commit --preview

​
Add Context for Clarity

Provide context for better messages: 
forge commit fix: handle edge case in date parsing

​
Review Before Committing

Always review the generated message and reject if it’s not accurate.

​
Limit Diff Size for Large Changes

For large changesets, use --max-diff: 
forge commit --max-diff 50000

​
Integration with Git

​
Stage All Changes

git add -A && forge commit

​
Stage Specific Files

git add src/auth/*.ts && forge commit authentication changes

​
Amend Last Commit

# Generate new message
forge commit --preview > .git/commit-msg.txt

# Amend with new message
git commit --amend -F .git/commit-msg.txt

​
Configuration

No additional configuration needed. The command uses your active Forge model and provider.
  • git add - Stage changes before committing
  • git status - View changes before generating message
  • git diff --staged - Preview staged changes
  • forge suggest - Get shell command suggestions

​
Notes

  • Requires staged changes (git add)
  • Works with any Git repository
  • Uses your configured Forge model
  • Respects your repository’s commit message style
  • --max-diff helps control API costs for large changes
  • Multiple words in custom text don’t need quotes
  • Preview mode is useful for reviewing before committing
