What problem does it solve? Adding a feature to an unfamiliar or large codebase often leads to architectural drift, duplicated abstractions, and missed test or documentation updates. This Skill inspects the actual repository and produces a concrete, repository-aware implementation plan before any code is written. ## Core Features & Use Cases - Architecture Mapping: Locates relevant entry points, modules, routes, and data flows, then identifies which existing abstractions to extend rather than duplicate. - Convention Discovery: Detects naming, folder organization, testing, styling, and documentation patterns from existing code so the plan mirrors project conventions. - Full-Surface Planning: Produces an ordered implementation plan covering code changes, unit/integration/e2e tests, docs, examples, demo updates, risks, and a handoff checklist. - Use Case: A maintainer asks where a new export feature should live in a monorepo. The Skill inspects the target package, cites the files that shaped its reasoning, and returns a step-by-step plan a coding agent can implement safely. ## Quick Start Ask the agent to plan how your proposed feature fits into this repository, including which files will change and how to update tests, docs, and demos.
