deepwiki

name	deepwiki
description	This skill should be used when the user mentions a "GitHub repository", provides a "github.com" URL, uses "owner/repo" format, asks to "explain a codebase", "how does this repo work", "what is the architecture of X", "how is X implemented", "tell me about" an open-source project, asks to compare how multiple open-source projects implement a feature, or needs documentation about a library's internals. Also use when the user invokes /deepwiki.

DeepWiki - GitHub Repository Documentation

Query documentation for any public GitHub repository using DeepWiki MCP tools. DeepWiki provides auto-generated, AI-powered documentation covering architecture, code structure, and implementation details. No authentication required.

Repository Detection

Extract the repository identifier from user input. Normalize to owner/repo format:

Input Format	Example	Extracted
Full URL	https://github.com/vercel/next.js	vercel/next.js
Short URL	github.com/facebook/react	facebook/react
Shorthand	denoland/deno	denoland/deno
With path	github.com/owner/repo/blob/main/src/index.ts	owner/repo

Strip trailing slashes, query parameters, and path segments beyond owner/repo.

Tool Selection

Choose based on the user's intent:

Broad Exploration

User wants to understand a repository overall, browse docs, or "tell me about X":

1. Call mcp__plugin_deepwiki_deepwiki__read_wiki_structure with repoName
2. Present the outline as a navigable list
3. Offer to deep-dive into specific topics

Specific Question

User asks a direct question about a repository:

1. Call mcp__plugin_deepwiki_deepwiki__ask_question with repoName and question
2. Present the AI-powered answer

Deep Reading

User wants comprehensive docs on a repository:

1. Call mcp__plugin_deepwiki_deepwiki__read_wiki_contents with repoName
2. Present and summarize the documentation content

Prefer ask_question for specific queries

When the user asks "how does X work" or "what is the architecture of Y", use ask_question directly. It provides the most targeted, context-grounded answers.

Slash Command Handling

When invoked via /deepwiki:

• With repo + question (/deepwiki vercel/next.js how does routing work?): use ask_question
• With repo only (/deepwiki vercel/next.js): use read_wiki_structure to show the outline
• No arguments (/deepwiki): ask the user which repository to query

Response Format

Structure all responses:

1. State the repository (owner/repo)
2. Present information organized by topic or relevance
3. Include architecture descriptions and code references when available
4. Suggest follow-up queries when appropriate

Guidelines

• Always extract owner/repo before making any tool call
• Do not fabricate repository information -- rely solely on DeepWiki tool results
• If a tool call fails, suggest verifying the repository name and that it is public
• For multi-repo comparisons, call tools for each repo and synthesize
• When the user mentions a well-known library without specifying the repo, infer the GitHub repo if confident (e.g., "React" → facebook/react, "Next.js" → vercel/next.js)
