What is OrchestKit?
OrchestKit is a free, open-source (MIT) plugin for Claude Code, Anthropic's agentic command-line coding tool. It packages 114 skills, 37 agents, and 216 lifecycle hooks into a single install — encoding security patterns and quality gates so the agent works to your standards out of the box. It runs locally inside Claude Code; it is not a hosted service and not an editor autocomplete.
Skills · 114
Reusable knowledge modules for auth, migrations, API design, testing, and review — loaded on demand at zero runtime cost.
Agents · 37
Specialist personas — security auditors, backend architects, frontend devs — each with curated tools and skills, run in parallel.
Hooks · 216
TypeScript lifecycle automation that blocks dangerous commands, injects context, and enforces security — non-blocking, automatic.
How it compares: unlike editor assistants such as Cursor or GitHub Copilot — which autocomplete inside the IDE — OrchestKit operates at the agent layer, making Claude Code more capable rather than typing alongside you. Install with claude install orchestkit/ork. See the full comparison.

Why OrchestKit
OrchestKit is built for Claude Code developers. Unlike editor assistants such as Cursor or GitHub Copilot — which autocomplete inside your IDE — OrchestKit operates at the agent layer, making the Claude Code agent more capable with 114 curated skills, 37 specialist agents, and 216 guardrail hooks. It is free, open source, and runs locally. See the side-by-side comparison or read about the project.
Built for AI agents, too
Every page on this site is agent-readable: append .md to any URL (or send Accept: text/markdown) for raw Markdown, start from /llms.txt for the navigation index, or read the OpenAPI spec for the full read-only API. No authentication, no account.
MCP server
The OrchestKit Docs MCP server speaks Streamable HTTP at https://orchestkit.yonyon.ai/api/mcp with two read-only tools: documentation search and Markdown page fetch. It is published in the official MCP registry as io.github.yonatangross/orchestkit, and listed on Smithery and mcp.so. Server card: /.well-known/mcp/server-card.json.
NLWeb natural-language queries
Ask questions in plain language at the NLWeb /ask endpoint — GET /ask?query=... or POST a JSON body — and get ranked documentation answers with NLWeb _meta. Add ?streaming=true for Server-Sent Events (start, result, complete).
WebMCP in the browser
For in-browser agents, every page registers WebMCP tools via navigator.modelContext: search_docs, list_skills, and get_skill — the same capabilities as the remote MCP server, available without leaving the page.
Agent skills directory
All OrchestKit skills are self-published on skills.sh straight from this repository — install any of them with npx skills add yonatangross/orchestkit.
Discovery endpoints
Agent card at /.well-known/agent-card.json, skills index at /.well-known/agent-skills/index.json, API catalog at /.well-known/api-catalog, and auth posture (none needed) at /auth.md. For hosted-search outages, see the ask-fallback guide.
What is OrchestKit?
OrchestKit is a free, MIT-licensed plugin for Claude Code, Anthropic's agentic coding CLI. It packages 114 reusable skills, 37 specialist agents, and 216 lifecycle hooks into a single install, so the agent applies proven auth, migration, API-design, testing, and security patterns to your codebase without being re-taught every session. It runs entirely inside Claude Code — there is no hosted service, no account, and no telemetry requirement.
OrchestKit is built and maintained by Yonyon, the software studio of Yonatan Gross. Developer resources live at predictable URLs: the documentation, the developer resource hub (OpenAPI spec, MCP server, SDK packages, auth and API policy), and the open-source repository on GitHub. AI agents can query the docs through the NLWeb /ask endpoint or the OrchestKit Docs MCP server, hosted and as a Docker image.
