What specific types of analysis can I perform?

You can analyze dependencies, dead code, API surface area, type safety, error handling, test coverage, security vulnerabilities, and custom architectural patterns.

Can I define custom patterns for the analysis?

By using the --type=patterns flag, you can interactively prompt the agent to search for specific custom structures such as permission checks, DTO patterns, or business logic standards.

Does it support TypeScript-specific checks?

Yes, it utilizes specialized tools like mcp-tsc for persistent TypeScript diagnostics and type-safety audits, including detection of 'any' types and unsafe casts.

How does this skill avoid cluttering my main session?

It launches an isolated sub-agent (forked context) to perform heavy search and analysis operations in the background, keeping your main conversation history clean and focused.

セキュリティとテスト

Performs comprehensive codebase audits and architectural exploration using isolated sub-agents to avoid session clutter.

Deep Codebase Analysis allows Claude to conduct intensive repository explorations without exhausting the context window of your main session. By launching an isolated sub-agent, this skill performs heavy-duty Grep/Glob operations, TypeScript diagnostics, and pattern matching to identify technical debt, security vulnerabilities, and architectural inconsistencies. It is ideal for large-scale refactors, security audits, or onboarding onto complex legacy projects, delivering a structured report with severity ratings and specific fix suggestions while you continue your primary development tasks in parallel.
