SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Onboarding onto an unfamiliar codebase is slow and error-prone when documentation is missing or outdated. This Skill systematically explores a repository and produces a guided, step-by-step tour so engineers can understand architecture, data flow, and module responsibilities without reading every file themselves. ## Core Features & Use Cases - Systematic Code Exploration: Reads config files, maps directory structure, traces entry points and data flow, and builds a dependency graph with classified connections (data-flow, function-call, event, dependency). - Dual Output Formats: Produces a portable Markdown document with Mermaid diagrams plus a self-contained interactive HTML file featuring step navigation, syntax highlighting, and a force-directed architecture SVG with click-to-navigate nodes. - Configurable Depth and Modes: Supports overview, standard, and deep exploration levels, plus a compact agent mode that outputs a terse module briefing for autonomous coding agents. - Use Case: A new engineer joins a team maintaining an unfamiliar Python service. Run the walkthrough on the repo to get a guided tour covering architecture, core data flow, module deep dives, and testing strategy, shareable as an HTML page. ## Quick Start Ask the assistant to walk you through the current project codebase at standard depth and generate the Markdown and HTML walkthrough files.

FAQPage Schema
How do I generate a walkthrough of an unfamiliar codebase?▼

Invoke the skill with a target directory path and it explores the code systematically, then writes a Markdown document and an interactive HTML file with step-through navigation. Use the --depth flag to choose overview, standard, or deep coverage.

What output formats does a codebase walkthrough produce?▼

It produces two files: a portable Markdown document with inline Mermaid diagrams, and a self-contained HTML file with sidebar navigation, syntax-highlighted code snippets, and an interactive force-directed architecture SVG. Both contain the same walkthrough content.

Can I generate codebase context for an autonomous coding agent?▼

Yes, use --mode agent to produce a compact single Markdown file covering files, architecture, patterns, key interfaces, and gotchas within a 2,000-5,000 token budget. It skips interactive diagrams and is scoped to a module or directory rather than a full codebase.

Does the walkthrough HTML work without an internet connection?▼

The HTML is self-contained and works over the file:// protocol, but Prism.js and Mermaid.js load from CDNs. If the CDN resources fail, prose, code snippets, and navigation still function; only syntax highlighting and diagram rendering are degraded.

What are the limitations of automated codebase walkthroughs?▼

Very large codebases may exceed complete coverage at the chosen depth, in which case omitted sections are stated explicitly with reasons. The interactive SVG layout is O(n²) per iteration, so diagrams are reduced to directory-level nodes beyond roughly 50-60 modules.
