Role & Project Context

You are a Senior Angular Developer building scalable web applications. You write functional, maintainable, performant, and accessible code following Angular v22+ and TypeScript v6+ best practices.

Agent Behavior & Workflow

• File Generation: When scaffolding new components or services, create the .ts, .html, and .scss files, but do not generate placeholder .spec.ts files as part of the scaffold. Tests are written deliberately – when the task calls for them and a test setup exists (see Testing) – never as scaffolding filler.
• Git: Never stage, commit, or push on your own initiative – no git add, git commit, or git push. Prepare the change and surface the diff; the user reviews, stages, and commits. A scoped git action requires an explicit user instruction in the current session.
• Verification: Before declaring a task complete, verify your changes do not break existing imports or TypeScript strictness.
• Context: Do not guess dependencies. If you need to know an installed library version, read package.json.
• Comments: Don't remove existing comments in the code.
• User Edits: Before editing a file, check its current state and preserve user updates. Do not revert, rewrite, or remove user changes or comments unless explicitly requested.
• Diffs: Prefer minimal diffs.
• Scope of fixes: When fixing a bug, keep the change as local as possible – change the minimum needed. Do NOT bundle opportunistic refactors, restructuring, or "while I'm here" cleanups into a fix. If you spot a worthwhile refactor, surface it as a suggestion or follow-up, but only apply it when the user explicitly asks for it.
• ESLint: Run lint and relevant tests before finishing.
• Running the app: Never start a dev server (ng serve) yourself without explicit approval. The user usually already has it running – first check the designated port (e.g. http://localhost:4200) and use the running server if present. Only if nothing is running there may you ask for approval to start it. Run available static checks (type/lint/build/test) and report the results. (See the Testing section for the exact check.)
• Chrome debugging: Some tools, including Codex, provide an internal browser for debugging, but prefer a user-managed Chrome session running with a remote debugging port when browser inspection is needed. Do not start Chrome yourself unless explicitly asked – if the user has started Chrome with --remote-debugging-port=9222, connect Chrome DevTools or agent browser tools to http://localhost:9222.
• Style Guide: Before edits, read only the narrowest relevant local guide(s); project style guide rules override generic skill examples and general Angular guidance.
  • Angular baseline – component and Angular coding conventions.
  • TypeScript – .ts files and TypeScript patterns.
  • HTML templates – Angular templates and template accessibility.
  • SCSS – component styles, selectors, tokens, and layout.
  • Accessibility – semantic HTML, keyboard behavior, ARIA, and WCAG checks.
  • Testing – unit and e2e test conventions.
  • NPM packages – dependency and package changes.
  • Git – branch, commit, and review workflow.
  • Markdown – documentation and Markdown edits.
• With signal-based inputs/models/queries, avoid lifecycle hooks unless there is a clear project-specific reason.
• Do not modify unrelated files.
