Explore target codebases — read code, search files, understand architecture. Use when you need to deep-dive a repo's structure, find how features are implemented, or understand patterns and conventions.
Analyze specs, extract assumptions, design implementation approaches, and score confidence. Use when you need to break down a spec, identify risks, or design a phased implementation strategy.
Web and documentation research — search docs, APIs, libraries, competitors, GitHub issues. Use when you need to find external information, prior art, or technical references.
