Repository Guidelines

Project Structure & Module Organization

This is a Firefox WebExtension (Manifest V2) with npm-based development tooling.

• manifest.json defines the extension metadata, the ChatGPT search provider, the background script, the options panel, and the keyboard command.
• lib/ holds pure logic with no browser dependencies: defaults.js, build-url.js, and settings.js. This is the unit-tested core.
• background/background.js is an ES-module background script that registers the context menu and the keyboard command.
• options/ is the options panel rendered inline in about:addons.
• test/ holds node:test unit tests. Excluded from the packaged ZIP.
• icons/ contains size-specific PNG artwork named powered-by-openai-icon-<size>x<size>.png.
• web-ext-config.mjs controls linting, local execution, and ZIP packaging.
• docs/superpowers/ holds specs and plans. Excluded from the packaged ZIP.
• .gitea/workflows/firefox-extension.yml validates pull requests and protected branches.
• README.md, CHANGELOG.md, and LICENSE.txt cover usage, releases, and licensing.

Browser Scope

Firefox Desktop is the only current implementation and release target. Do not add Chrome, Brave, Chromium, or other browser packaging—or modify the sibling Chrome repository—unless a task explicitly requests it. Future ports remain desirable, so prefer standard WebExtension APIs where they preserve Firefox behavior and isolate unavoidable Firefox-specific code.

Build, Test, and Development Commands

• npm ci installs the exact dependencies from package-lock.json; use Node.js 22 or newer.
• npm run dev launches a temporary Firefox profile with automatic extension reload.
• npm run lint runs strict Mozilla extension validation.
• npm run test:unit runs the node:test unit tests over test/.
• npm run build creates the unsigned ZIP under web-ext-artifacts/.
• npm test runs lint, unit tests, and build together; run it before every pull request.

Coding Style & Naming Conventions

Use two-space indentation in JSON, YAML, and JavaScript configuration. Preserve logical key grouping in manifest.json. Use lowercase, hyphenated filenames and include dimensions in icon names. Keep changes focused and avoid adding runtime dependencies without a concrete need.

Testing Guidelines

Unit tests cover the pure logic in lib/ via node:test; automated checks otherwise cover manifest validation and packaging, not browser behaviour. Note node --test exits 0 when it discovers no test files, so confirm a non-zero test count rather than trusting the exit code alone.

After npm test, use npm run dev and confirm:

• gpt <query> opens ChatGPT, the provider stays non-default, and Firefox search settings can configure it.
• The Options/Preferences tab renders all five settings plus Restore defaults, in both light and dark themes and at a narrow window width, and values persist across a restart.
• The right-click Ask ChatGPT item appears only when text is selected.
• Alt+Shift+G acts on the selection, including a selection inside an iframe, and opens a blank chat when nothing is selected or on a restricted page such as about:config. Press the key to test this — commands.getAll() reports a shortcut as registered even when Firefox has silently overridden it.

Inspect ZIP contents whenever packaging rules or assets change; test/ and docs/ must never appear, not even as empty directory entries.

Gitea Actions runs checks for every pull request and pushes to develop and main. Only successful main pushes upload an unsigned build artifact; CI does not publish to AMO.

Commit & Pull Request Guidelines

Recent history uses short, lowercase prefixes such as doc: and build: (for example, doc: fix git url). Follow <type>: <concise summary> and keep each commit focused.

Pull requests should explain the user-visible effect, list manual Firefox checks, and link the relevant issue. Include screenshots for icons or browser-visible metadata. Explicitly call out permission, search URL, privacy, and packaging changes.

Security & Privacy

Do not commit credentials or API keys. New permissions, telemetry, intermediary servers, or data collection require explicit justification and matching privacy documentation.

Permissions are deliberately limited to storage, menus, and activeTab, which add no line to Firefox's install prompt. Do not add tabs, notifications, webNavigation, or any host permission without re-reading docs/superpowers/specs/2026-07-29-extension-options-design.md — each was considered and rejected there, and Appendix B records a feature rejected on security grounds that must not be revived without clearing the bar documented with it.
