github-codebase-search
github-codebase-search
Semantic search for public GitHub repositories powered by MorphLLM — an RL-trained subagent that runs parallel grep+read calls against the GitHub API to answer natural language questions about code. No cloning required.
Requires MORPH_API_KEY environment variable.
When to Use
- Understanding how a library or framework works internally (e.g., "how does Next.js resolve middleware?")
- Investigating upstream bugs or behavior in open-source dependencies
- Learning from reference implementations in well-known repos
- Tracing code paths in a repo you haven't cloned locally
- Exploring how an OSS project is structured or architected
When NOT to Use
- Questions about the local codebase — use codebase-search
- Private repositories (GitHub API access required)
- Simple documentation lookup — use context7

deps-dev
Look up the latest stable version of any open-source package across npm, PyPI, Go, Cargo, Maven, and NuGet. Use when the user asks 'what's the latest version of X', 'what version should I use', 'is X deprecated', 'how outdated is my package.json/requirements.txt/Cargo.toml', or needs version numbers for adding or updating dependencies. Also covers pinning versions, checking if packages are maintained, or comparing installed vs latest versions. Do NOT use for private/internal packages or for looking up documentation (use context7).
151council-review
Multi-perspective code review that synthesizes findings from multiple reviewers into a unified report. Use when the user asks to review code changes, audit a diff, check code quality, review a PR, review commits, or review uncommitted changes. Also covers 'code review', 'review my changes', 'check this before I merge', or wanting multiple perspectives on code. Do not use for documentation/markdown review or trivial single-line changes.
101oracle
Deep analysis and expert reasoning. Use when the user asks for 'oracle', 'second opinion', architecture analysis, elusive bug debugging, impact assessment, security reasoning, refactoring strategy, or trade-off evaluation — problems that benefit from deep, independent reasoning. Do not use for simple factual questions, code generation, code review (use council-review), or tasks needing file modifications.
99context7
Fetch up-to-date documentation for any open-source library or framework. Use when the user asks to look up docs, check an API, find code examples, or verify how a feature works — especially with a specific library name, version migration, or phrases like 'what's the current way to...' or 'the API might have changed'. Also covers setup and configuration docs. Do NOT use for general programming concepts, internal project code, or version lookups (use deps-dev).
86conventional-commit
Generates git commit messages following Conventional Commits 1.0.0 specification with semantic types (feat, fix, etc.), optional scope, and breaking change annotations. Use when committing code changes or creating commit messages.
58react-web-advanced
Web-specific React patterns for type-safe file-based routing, route-level data loading, server-side rendering, search param validation, code splitting, and list virtualization. Use when building React web apps with route loaders, SSR streaming, validated search params, lazy route splitting, or virtualizing large DOM lists. Do not use for React Native apps — use react-native-advanced instead.
