Github Action

GitHub Action Skill

You are running inside a GitHub Actions workflow, triggered by a user mentioning @letta-code in a GitHub issue or pull request comment.

Environment Variables

Updating Your Tracking Comment

You have a tracking comment that shows your progress. Always read the current comment before updating to preserve the footer.

How to Update

1. Read the current comment first:

gh api /repos/$GITHUB_REPOSITORY/issues/comments/$LETTA_COMMENT_ID

2. Note the footer at the bottom of the comment body - it looks like:

---
🤖 **Agent:** [`agent-xxx`](https://app.letta.com/agents/agent-xxx) • **Model:** opus
[View in ADE](...) • [View job run](...)

3. Update with your new content + the same footer:

gh api /repos/$GITHUB_REPOSITORY/issues/comments/$LETTA_COMMENT_ID \
  -X PATCH \
  -f body="Your new content here

---
🤖 **Agent:** ... (copy the footer from step 1)"

Important: Always preserve the footer in every update so users can access the ADE and job run links while you're working.

Git Operations

Git is pre-configured with authentication. Use standard commands:

# Stage changes
git add <files>

# Commit with descriptive message
git commit -m "feat: description of changes"

# Push to the working branch
git push origin $BRANCH_NAME

Commit Message Convention

Follow conventional commits:

• feat: - New feature
• fix: - Bug fix
• docs: - Documentation changes
• refactor: - Code refactoring
• test: - Adding tests
• chore: - Maintenance tasks

Creating Pull Requests

If working on an issue (not already a PR), create a PR after pushing:

gh pr create \
  --title "feat: description" \
  --body "Fixes #<issue_number>

## Summary
- What was changed

## Test Plan
- How to verify

---
Generated with [Letta Code](https://letta.com)" \
  --base $BASE_BRANCH \
  --head $BRANCH_NAME

IMPORTANT: Always include a closing keyword (Fixes #N, Closes #N, or Resolves #N) in the PR body when the PR addresses an issue. This:

1. Links the PR to the issue in GitHub 2. Automatically closes the issue when the PR is merged 3. Enables conversation continuity - the agent will have access to the full context from the issue discussion when working on the PR

Checking CI Status

To check CI status on the current PR:

gh pr checks --repo $GITHUB_REPOSITORY

gh CLI Cheatsheet

The gh CLI is pre-authenticated and available. Here are the most common commands you'll need:

Working with Pull Requests

# List open PRs
gh pr list --repo $GITHUB_REPOSITORY

# View PR details
gh pr view <number> --repo $GITHUB_REPOSITORY

# Checkout an existing PR's branch (to push updates to it)
gh pr checkout <number>

# Check CI status on a PR
gh pr checks <number> --repo $GITHUB_REPOSITORY

# Add a comment to a PR
gh pr comment <number> --body "Your comment" --repo $GITHUB_REPOSITORY

# View PR diff
gh pr diff <number> --repo $GITHUB_REPOSITORY

Working with Issues

# List open issues
gh issue list --repo $GITHUB_REPOSITORY

# View issue details
gh issue view <number> --repo $GITHUB_REPOSITORY

# Add a comment to an issue
gh issue comment <number> --body "Your comment" --repo $GITHUB_REPOSITORY

GitHub API (for advanced operations)

# Get PR review comments
gh api repos/$GITHUB_REPOSITORY/pulls/<number>/comments

# Get PR reviews
gh api repos/$GITHUB_REPOSITORY/pulls/<number>/reviews

# Get issue comments
gh api repos/$GITHUB_REPOSITORY/issues/<number>/comments

Pushing to an Existing PR

If you need to update an existing PR (not the one you're currently on):

# Checkout the PR's branch
gh pr checkout <number>

# Make your changes, then commit and push
git add <files>
git commit -m "fix: description"
git push origin HEAD

Discovering More Commands

The gh CLI has many more capabilities. Use --help to explore:

gh --help              # List all commands
gh pr --help           # PR-specific commands
gh issue --help        # Issue-specific commands
gh api --help          # API request help

Important Notes

1. Always update the comment before long operations so users know you're working 2. Never force push - only regular pushes are allowed 3. Check for existing changes before committing with git status 4. Pull before push if the branch may have been updated: git pull origin $BRANCH_NAME 5. Use `gh --help` to discover additional gh CLI capabilities beyond this cheatsheet
