What Code Overview does

Code Overview produces a progressive-disclosure summary of unfamiliar code or a pull request’s changes, explaining why it exists, what it does, and where to start. Use it to get oriented before working on or reviewing code; it writes only a scratch file and does not change the target.

Code Overview is cataloged under Writing on DirSkills. Code Overview comes from a repository tagged claude, claude-code, claude-code-plugin, claude-skills and code-review.
