Quick Review

Well-structured skill for parallel codebase exploration with clear guidance on when to use sequential vs. parallel approaches. The description accurately captures the skill's purpose, and the document provides concrete patterns including tool usage examples and structured output formats. The distinction between quick searches and broad understanding is valuable. The novelty is moderate - while parallel subagent spawning is useful for reducing token costs in large codebases, the underlying techniques (Glob, Grep, Task spawning) are relatively standard. The skill excels in providing a reusable pattern with clear principles and YAML output templates that make results actionable. Minor improvement areas: could benefit from concrete examples of 'specific questions' to ask explorers, and cost/time tradeoff guidance for when parallelization is worth it.
