🌊 Deep Wiki

AI-Powered Wiki Generator for Code Repositories — GitHub Copilot CLI Plugin

Generate comprehensive, structured, Mermaid-rich documentation wikis for any codebase — with dark-mode VitePress sites, onboarding guides, and deep research capabilities. Distilled from the prompt architectures of OpenDeepWiki and deepwiki-open.

/deep-wiki:crisp

# Just the structure
/deep-wiki:catalogue

# Single page with dark-mode diagrams

/deep-wiki:build

# Research a topic (evidence-based, 5 iterations)
/deep-wiki:research How does the caching layer work?

# Generate llms.txt for LLM-friendly access
/deep-wiki:llms

How It Works

Repository → Scan → Catalogue (JSON TOC) → Per-Section Pages → Assembled Wiki
                                                    ↓
                                         Mermaid Diagrams + Citations
                                                    ↓
                                         Onboarding Guides (Contributor, Staff Engineer, Executive, PM)
                                                    ↓
                                         VitePress Site (Dark Theme + Click-to-Zoom)
                                                    ↓
                                         AGENTS.md Files (Only If Missing)
                                                    ↓
                                         llms.txt + llms-full.txt (LLM-friendly)
                                                    ↓
                                         GitHub Pages Deployment (Optional)

Design Principles

1. Source-linked citations: Before any task, resolve the source repo URL (or confirm local). All citations use [file:line](https://github.com/microsoft/skills/blob/cf77b1efbf3117501f4727c476894751311ee885/.github/plugins/deep-wiki/REPO_URL/blob/BRANCH/file/README.md#Lline) for remote repos, (file:line) for local
2. Structure-first: Always generate a TOC/catalogue before page content
3. Evidence-based: Every claim cites file_path:line_number with clickable links — no hand-waving
4. Diagram-rich: Minimum 3–5 dark-mode Mermaid diagrams per page using multiple diagram types, with click-to-zoom and `` comment blocks. More diagrams = better — use them liberally for architecture, flows, state, data models, and decisions.
5. Table-driven: Prefer tables over prose for any structured information. Use summary tables, comparison tables, and always include a "Source" column with citations.
6. Progressive disclosure: Big picture first, then drill into details. Every section starts with a TL;DR.
7. Hierarchical depth: Max 4 levels for component-level granularity
8. Systems thinking: Architecture → Subsystems → Components → Methods
9. Never invent: All content derived from actual code — trace real implementations
10. Dark-mode native: All output designed for dark-theme rendering (VitePress)
11. Depth before breadth: Trace actual code paths, never guess from file names
12. Agent-discoverable: Output placed at standard paths (llms.txt at repo root, AGENTS.md in key folders) so coding agents and MCP tools find documentation automatically

Agent & MCP Integration

The generated output is designed to be discoverable by coding agents using the GitHub MCP Server or any MCP-compatible tool:

File	Path	Discovery Method
llms.txt	Repo root (./llms.txt)	Standard llms.txt spec location — agents check here first via get_file_contents
llms-full.txt	wiki/llms-full.txt	Full inlined docs — agents load this for comprehensive context
AGENTS.md	Root + key folders	Standard agent instructions file — references wiki docs in Documentation section
Wiki pages	wiki/**/*.md	Searchable via search_code — all pages contain source-linked citations
llms.txt	wiki/.vitepress/public/	Served at /llms.txt on deployed VitePress site

How it works with GitHub MCP:

1. Agent calls get_file_contents on llms.txt → gets project summary + links to all wiki pages
2. Agent calls get_file_contents on specific wiki pages → gets full documentation with source citations
3. Agent calls search_code with patterns → finds relevant wiki sections across the repository
4. Agent reads AGENTS.md → Documentation section points to wiki and onboarding guides
