SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? New engineers joining a project waste days or weeks reading code without a map, guessing which files matter and how modules connect. This Skill reads the actual source code, traces real execution paths, and produces a fact-grounded orientation map so a developer understands the codebase structure in one pass. ## Core Features & Use Cases - Repository Inventory & Entry-Point Discovery: Identifies manifests, framework markers, startup files, routers, and CLI commands to determine how the system starts. - Execution Path Tracing: Follows requests, events, and function calls end-to-end through routing, business logic, persistence, and output layers, citing exact files. - Three-Level Explanation Output: Returns a one-line summary, a five-minute overview, and a deep dive with file-by-file responsibilities and code flows. - Use Case: A developer joins a Bun monorepo with 22 packages and asks where to start. The Skill inspects the workspace, identifies entry points and package boundaries, and returns a Codebase Orientation Map naming the three files to read first. ## Quick Start Ask the agent to explain this repository and produce a codebase orientation map with entry points, key files, and main execution paths.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I onboard a new developer to an unfamiliar codebase quickly?▼

Start by inventorying manifests and entry points, then trace one or two concrete execution paths end-to-end. This Skill automates that process, returning a one-line summary, a five-minute overview, and a deep dive with exact file references.

How to trace a request through a codebase I don't know?▼

Locate the entry point (router, handler, or CLI command), then follow calls through orchestration, business logic, and persistence layers. The Skill performs this tracing and lists every file involved in the path.

Does codebase onboarding analysis work for monorepos and polyglot projects?▼

Yes. It recognizes workspace structures like Nx, Turborepo, Bazel, and Lerna, distinguishes libraries from applications, and traces cross-language boundaries through API contracts, shared config, and build orchestration.

Can the onboarding agent suggest refactoring or code improvements?▼

No. It is strictly read-only and descriptive by design. It states facts grounded in inspected code and never proposes changes, optimizations, or implementation advice.

What are the limitations of automated codebase explanation?▼

Explanations only cover files actually inspected, so partial reads yield partial maps. The Skill explicitly states which files were and were not inspected rather than claiming full repository understanding.
