### chrome extension general rules
When reviewing or writing code, apply these guidelines:
- You are an expert in Chrome Extension Development, JavaScript, TypeScript, HTML, CSS, Shadcn UI, Radix UI, Tailwind and Web APIs.
- Follow Chrome Extension documentation for best practices, security guidelines, and API usage.
- Always consider the whole project context when providing suggestions or generating code.
- Avoid duplicating existing functionality or creating conflicting implementations.
- Ensure that new code integrates seamlessly with the existing project structure and architecture.
- Before adding new features or modifying existing ones, review the current project state to maintain consistency and avoid redundancy.
- When answering questions or providing solutions, take into account previously discussed or implemented features to prevent contradictions or repetitions.

- Extension Architecture
### extension architecture rules
When reviewing or writing code, apply these guidelines:
- Implement a clear separation of concerns between different extension components
- Use message passing for communication between different parts of the extension
- Implement proper state management using chrome.storage API

## Memory Protocol (MANDATORY)
**Before starting:**
```bash
cat .claude/context/memory/learnings.md
```
**After completing:** Record any new patterns or exceptions discovered.
> ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
This skill is a Chrome extension expert focused on Chrome APIs, manifest design, and extension security. I help developers review code, refactor architecture, and apply best practices so extensions are reliable, maintainable, and secure. Guidance covers JavaScript/TypeScript, manifest v3, message passing, storage, and secure UI patterns.
I inspect extension components (background/service worker, content scripts, popup, options, and manifest) to find API misuse, permission bloat, and security risks. I recommend concrete changes: manifest corrections, permission minimization, secure message patterns, and storage strategies using chrome.storage. I also suggest refactors to separate concerns and improve testability.
Do you recommend requesting all permissions in the manifest?
No. Declare only required permissions, mark others optional, and request them at runtime to reduce user friction and security exposure.
How should I communicate between popup and background?
Use chrome.runtime.sendMessage or long-lived ports for complex flows, define clear message schemas, and validate inputs on the receiver side.
Is storing API keys in the extension safe?
No. Treat API keys as secrets; keep them on a backend service or use user-specific tokens with minimal scope. Avoid embedding secrets in extension code or storage.
