What problem does it solve? Before committing to spec a feature, you often need to understand what it involves, what it depends on, and how big it is. This Skill reads your build plan and project overview and produces a concise, read-only briefing so you can decide whether to spec, reorder, split, or clear a blocker first. ## Core Features & Use Cases - Feature Briefing: Explains what a feature is, what it depends on, what it unblocks, what files and systems it touches, and its likely size. - Split Prediction: Flags whether a large feature will likely split into sub-items (e.g., 5a, 5b, 5c) before you run the spec step. - Blocker Detection: Honestly reports missing prerequisites, stub plans, or stale overviews instead of inventing scope. - Use Case: Run /brief 5 to preview the submission draft flow feature, learn it depends on an unbuilt API backend, and decide to clear that blocker before running /feature 5. ## Quick Start Ask the assistant to brief the next unchecked feature in build-plan.md, or specify one by number or name such as "/brief 4".
