PR Hygiene

Turn the current work into a PR a human can review in one pass.

Before opening

• Branch contains one logical change (or clearly labeled stacked commits)
• No leftover console.log, debugger, TODO: temp, commented-out blocks you added
• No unrelated formatting-only churn
• Secrets, .env, and local-only files are not staged
• Diff matches the stated goal — nothing "extra helpful"

Description template

Use this structure (adapt section names to the host: GitHub/GitLab):

## Summary
<1–3 bullets: what and why>

## Test plan
- [ ] <how you verified>
- [ ] <edge case worth checking>

## Notes
<risks, follow-ups, screenshots if UI>

Commit / PR title

• Imperative, specific: fix checkout: reject expired discount codes
• Not: update stuff, fix, WIP, address comments

Reviewer empathy

Call out:

• Files that look scary but are mechanical (renames, generated)
• Behavior that changed for callers/API consumers
• Anything you are unsure about

Anti-patterns

• NEVER mix refactor + feature + dependency bump in one PR unless required
• NEVER force-push shared branches without warning
• NEVER open a PR with "tests TBD" and no plan
• NEVER bury breaking changes in the middle of the description

If asked to open the PR

1. Summarize the diff in your own words first
2. Draft title + body with the template
3. List residual risks in one short section
