Code Review
Automated code review and analysis
code-simplicity-reviewer
by ratacat
"Use this agent when you need a final review pass to ensure code changes are as simple and minimal as possible. This agent should be invoked after implementation is complete but before finalizing changes, to identify opportunities for simplification, remove unnecessary complexity, and ensure adherence to YAGNI principles. Examples: <example>Context: The user has just implemented a new feature and wants to ensure it's as simple as possible. user: \"I've finished implementing the user authentication system\" assistant: \"Great! Let me review the implementation for simplicity and minimalism using the code-simplicity-reviewer agent\" <commentary>Since implementation is complete, use the code-simplicity-reviewer agent to identify simplification opportunities.</commentary></example> <example>Context: The user has written complex business logic and wants to simplify it. user: \"I think this order processing logic might be overly complex\" assistant: \"I'll use the code-simplicity-reviewer agent to analyze the complexity..."
review
by rube-de
Deep-validate a single GitHub issue against the codebase: cross-reference file paths, detect already-implemented features, check for related PRs, verify dependencies, and deliver a structured verdict with recommended action. Triggers: review issue, validate issue, check issue status, is this issue still needed, issue review.

composio-connect
by Casper-Studios
Universal fallback for executing actions across 1,000+ apps when no other skill is available. Use this skill ONLY when user requests an action on an app/service not covered by other skills (e.g., Notion, Asana, Trello, HubSpot, Airtable, Linear, Monday, Zendesk, Intercom, Stripe, Shopify, QuickBooks, Zoom, Microsoft 365, Dropbox, Box, Figma, Jira, Confluence, etc.). Do NOT use if another skill already handles the service. Triggers on requests to connect to external apps, execute actions on third-party services, or when user asks "can you actually do X" for an unsupported service.

feature-radar-ref
by runkids
Record external observations, ecosystem trends, and creative inspiration into .feature-radar/references/. MUST use this skill when the user mentions something interesting from outside their project — other tools, articles, approaches, or trends. Even casual mentions like "I saw a cool thing in X" should trigger this skill. Use when the user: - Says "I saw this cool thing in X's API", "check out how X handles this" - Shares a URL, article, talk, or research finding with relevant insights - Notes an ecosystem trend: new tools, standards, community patterns - Mentions a related project shipping a notable feature - Wants to bookmark external inspiration: "interesting approach", "save this" - Says "add reference", "log observation", "track this project" Do NOT use for internal learnings/patterns — that's feature-radar-learn's job. Do NOT use for prioritizing features — that's feature-radar's job.

by runkids
Discover new feature opportunities from creative brainstorming, user feedback, ecosystem trends, and cross-project research. Writes results to .feature-radar/opportunities/. MUST use this skill when the user wants to GENERATE new ideas — not evaluate existing ones. Trigger on any request to brainstorm, explore, discover, or find new feature ideas, even casual ones like "I wonder what else we could do" or "give me ideas". Use when the user: - Asks "what else could we build?", "give me feature ideas", "what are we missing?" - Wants to brainstorm, explore new directions, or refresh the opportunity backlog - Says "scan ecosystem", "scan opportunities", "find new features" - Asks to review GitHub issues, community feedback, or adjacent tools for inspiration - Mentions "explore", "discover", or "new directions" in a feature context Do NOT use for evaluating/prioritizing existing features — that's feature-radar's job.
