deepwiki-mcp-skill is a skill for Codex from holon-run/uxc. It costs 43 tokens per session (692 once invoked), scanned A, original, MIT.

A repository documentation reader that lets you ask questions about GitHub codebases and browse their indexed wiki pages.

In plain words
What is it for?
Use it to find APIs, learn how a codebase is structured, and get background on a GitHub repository.
Why use it?
It helps you understand an unfamiliar repository without manually searching through every file. The repository must first be indexed on DeepWiki.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deepwiki-mcp-skill scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DeepWiki Skill

Use this skill to query GitHub repository documentation and ask questions about codebases.

Prerequisites

  • uxc is installed and available in PATH.
  • Network access to mcp.deepwiki.com/mcp

Note: Repositories must be indexed on DeepWiki first. Visit https://deepwiki.com to index a repository.

Install uxc

Choose one of the following methods:

Homebrew (macOS/Linux):

brew tap holon-run/homebrew-tap
brew install uxc

Install Script (macOS/Linux, review before running):

curl -fsSL https://raw.githubusercontent.com/holon-run/uxc/main/scripts/install.sh -o install-uxc.sh
less install-uxc.sh
bash install-uxc.sh

Cargo:

cargo install uxc

Core Workflow

  1. Use fixed link command by default:

    • command -v deepwiki-mcp-cli
    • If missing, create it: uxc link deepwiki-mcp-cli mcp.deepwiki.com/mcp
    • deepwiki-mcp-cli -h
    • If command conflict is detected and cannot be safely reused, stop and ask skill maintainers to pick a different fixed command name.
  2. Ask a question about a repository:

    • deepwiki-mcp-cli ask_question repoName=owner/repo question='your question'
  3. Read wiki structure:

    • deepwiki-mcp-cli read_wiki_structure repoName=owner/repo
  4. Read wiki contents:

    • deepwiki-mcp-cli read_wiki_contents repoName=owner/repo

Available Tools

  • ask_question: Ask any question about a GitHub repository and get an AI-powered response
  • read_wiki_structure: Get a list of documentation topics for a repository
  • read_wiki_contents: View documentation about a repository

Usage Examples

Ask about a codebase

deepwiki-mcp-cli ask_question repoName=facebook/react question='How does useState work?'

Explore repository structure

deepwiki-mcp-cli read_wiki_structure '{"repoName":"facebook/react"}'

Read documentation

deepwiki-mcp-cli read_wiki_contents repoName=facebook/react

Output Parsing

The response is an MCP JSON envelope. Extract the content from .data.content[].text.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
