# DeepWiki - Repository Documentation

Query DeepWiki for AI-generated documentation about any public GitHub repository.

## Overview

DeepWiki (deepwiki.com) provides AI-generated documentation for GitHub repositories, including:
- Repository structure and architecture
- API documentation
- Code explanations
- Interactive diagrams

## Quick Start

**URL Pattern**: Replace `github.com` with `deepwiki.com` in any repo URL:
- `github.com/vercel/next.js` → `deepwiki.com/vercel/next.js`

## MCP Server Setup

DeepWiki provides a free MCP server with no authentication required for public repos.

### Add to Claude Code (one-time setup)

```bash
claude mcp add -s user -t http deepwiki https://mcp.deepwiki.com/mcp
```

### For Cursor/Windsurf

Add to your MCP config:
```json
{
  "mcpServers": {
    "deepwiki": {
      "serverUrl": "https://mcp.deepwiki.com/sse"
    }
  }
}
```

## Available MCP Tools

Once configured, these tools become available:

| Tool | Purpose |
|------|---------|
| `read_wiki_structure` | Get documentation topics/structure for a repo |
| `read_wiki_contents` | Retrieve actual documentation content |
| `ask_question` | Ask AI-powered questions about the repo |

## Usage Examples

### Via WebFetch (works immediately)

```bash
# Fetch documentation overview
WebFetch https://deepwiki.com/owner/repo "Summarize the architecture"

# Example
WebFetch https://deepwiki.com/vercel/next.js "How does routing work?"
```

### Via MCP (after setup)

Use the MCP tools directly:
- `mcp__deepwiki__read_wiki_structure` - Get repo structure
- `mcp__deepwiki__read_wiki_contents` - Get documentation
- `mcp__deepwiki__ask_question` - Ask questions

## Fallback: GitHub + AI

If DeepWiki lacks coverage for a repo, use GitHub API:

### Get Repository Overview

```bash
gh api repos/owner/repo | jq '{description, language, topics, stars: .stargazers_count}'
```

### Get README

```bash
gh api repos/owner/repo/readme --jq '.content' | base64 -d
```

### Get File Structure

```bash
gh api repos/owner/repo/git/trees/main?recursive=1 | \
  jq -r '.tree[] | select(.type == "blob") | .path' | head -50
```

## Wire Protocols

Two protocols are supported:
- **SSE** at `https://mcp.deepwiki.com/sse` - Official MCP spec
- **HTTP** at `https://mcp.deepwiki.com/mcp` - Cloudflare/OpenAI compatible

## Best Practices

1. **Use WebFetch first** - Works without MCP setup
2. **Check if repo is indexed** - Popular repos have better coverage
3. **Ask specific questions** - DeepWiki excels at targeted queries
4. **Fall back to GitHub** - For unindexed or private repos

## Limitations

- **Public repos only** - Private repos require Devin account
- **Coverage varies** - 50,000+ popular repos indexed
- **No authentication** - Can't access private documentation

jfrog

Included

Interact with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.

Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.
