What problem does it solve? Exploring an unfamiliar codebase before planning a change consumes context and risks anchoring bias. This Skill runs task-scoped reconnaissance in an isolated subagent and produces a structured, reviewable brief file instead of ad-hoc exploration notes. ## Core Features & Use Cases - Isolated reconnaissance: Dispatches a fresh-context scout subagent that performs broad orientation, a task-focused deep dive, and a disconfirmation pass, then writes a structured brief to docs/briefs/. - Dual input modes: Accepts either an idea reference (IDEA-<8hex>) fetched via the idea tool or freeform seed text, with automatic output-path derivation. - Gated workflow: Checks for pre-existing briefs with SHA comparison, validates the dispatched agent's output via a marker/freshness contract, and gates the result on a user commit/re-run/stop decision. - Use Case: Before writing a spec for a new feature, run the scout on your idea to get a brief mapping relevant files, key interfaces, call graphs, test patterns, and risk areas, then hand it off to /define-spec. ## Quick Start Ask the AI to scout the codebase for your task, for example by invoking the scout skill with an idea ID like IDEA-bbe89373 or a freeform description of the change you want to explore.
