Simple PR

Follow these steps to create a simple PR from staged changes:

Step 1: Check workspace state

Run: git status

Verify that all changes have been staged (no unstaged changes). If there are unstaged changes, abort and ask the user to stage their changes first with git add.

Also verify that we are on the main branch. If not, abort and ask the user to switch to main first.

Step 2: Ensure main is up to date

Run: git pull origin main

This ensures we're working from the latest code.

Step 3: Review staged changes

Run: git diff --cached

Review the staged changes to understand what the PR will contain.

Step 4: Generate commit message

Based on the staged changes, generate a concise commit message (1-2 sentences) that describes the "why" rather than the "what".

Display the proposed commit message to the user and ask for confirmation before proceeding.

Step 5: Create a new branch

Get the git username: git config user.name | tr ' ' '-' | tr '[:upper:]' '[:lower:]'

Create a short, descriptive branch name based on the changes (e.g., fix-typo-in-readme, add-retry-logic, update-deps).

Create and checkout the branch: git checkout -b {username}/{short-descriptive-name}

Step 6: Run pre-PR checks

Before committing, run these checks and fix any failures:

# License headers (every .rs, .proto, .py file needs the Apache 2.0 header)
bash scripts/check_license_headers.sh

# Clippy (must pass with no warnings)
cargo clippy --workspace --all-features --tests

# Format check
cargo +nightly fmt --all -- --check

Fix any issues found before proceeding. For license headers, the correct header for .rs files is:

// Copyright 2021-Present Datadog, Inc.
//
// Licensed under the Apache License, Version 2.0 (the "License");
// ...

Step 7: Commit changes

Commit with the message from step 4:

git commit -m "{commit-message}"

Step 8: Push and open a PR

Push the branch and open a PR:

git push -u origin {branch-name}
gh pr create --draft --title "{commit-message-title}" --body "{longer-description-if-needed}"

Report the PR URL to the user when complete.
