Pr Ready

PR Ready

Get changes ready to submit as a PR. Runs lint checks, reviews the PR checklist, and drafts a commit message.

Step 1: Run pre-commit checks

cd frontend && npx --no-install lint-staged --cwd ..

This runs stylelint, prettier, eslint, black, mypy, and ruff on staged files. Fix any errors before continuing.

If any .ftl files in privaterelay/pending_locales/ were changed, also run the Fluent linter:

moz-fluent-lint privaterelay/pending_locales --config privaterelay/locales/.github/linter_config.yml

Common fix: the linter requires right single quotation marks (') instead of straight apostrophes (') in English strings.

Step 2: Review PR checklist

Inspect git diff --cached (or git diff HEAD if nothing staged) and answer each item:

• l10n: Do changes touch any user-visible strings? If yes, have they been submitted to the l10n repo?
• Tests: Does the change fix a bug? If yes, is there a unit test to prevent regression?
• Docs: Do changes affect architecture, APIs, or workflows? If yes, is docs/ updated?
• UI: Do any UI changes follow the coding standards?
  • Protocol/Nebula colors used (see /frontend/src/styles/colors.scss)
  • CSS classes use mzp- prefix for Protocol, no prefix for custom styles
  • Simple selectors, minimal nesting, // comments in Sass
  • ESLint and stylelint rules satisfied

Report the checklist status. Flag any items that need attention before the PR is submitted.

Step 3: Draft a conventional commit message

Review the staged changes and write a commit message. Do NOT run git commit.

Format:

<type>[optional scope]: <description>

[optional body]

Types: feat, fix, refactor, perf, docs, test, build, ci, chore

Style:

• Short, declarative first line
• Active verbs, concrete nouns, no adverbs
• Body explains WHY, not what
• Breaking changes: use feat!: or feat(scope)!: + BREAKING CHANGE: footer

Present the message. Do not commit.

Step 4: Draft "How to test:" section

Write a brief testing guide for the PR reviewer. Base it on the staged changes.

Format:

How to test:
1. <setup step, if needed>
2. <action to take>
3. <what to verify>

Guidelines:

• Start with any required setup (flag, env var, account state)
• Describe the specific action a reviewer must take
• State the expected outcome — what they should see or not see
• Cover the happy path first, then edge cases if the change warrants it

Present the section. Do not open a PR.
