What problem does it solve? After an AI-assisted development session, developers struggle to reconstruct what changed and why. This Skill turns a detected change scope into a structured walkthrough document covering file-level intents, design decisions, spec drift, blind spots, and anticipated questions. ## Core Features & Use Cases - Scope-driven recap generation: Consumes a ScopeReport JSON (from detect-scope.js) and collects git evidence (log, diff stats, hunks) for the changed files only. - Mandatory blind-spot analysis: Applies heuristics (test-without-source, config-only changes, large deletions, security-sensitive paths) and always emits a Blind Spots section, even when empty. - Depth-controlled output: brief/normal/deep levels control top-N file coverage (5/10/15), code snippets, and whether Anticipated Questions are included. - Safe output handling: Redacts secrets before writing and confines output to the OS temp directory by default, with realpath-validated opt-in paths inside the repo. - Use Case: After Codex implements an auth feature, run the recap to get briefing-recap-2026-04-17.md with per-file explanations, spec-vs-implementation drift, and follow-up questions to review. ## Quick Start Ask the AI to run /recap-doc with the scope JSON produced by detect-scope.js, for example: generate a recap of this round of changes at normal depth.
