Orchestkit

OrchestKit is a free, open source plugin library for Claude Code, Anthropic's command line coding agent. It packages 110 skills, 36 agents and 169 lifecycle hooks into one install, encoding security patterns and quality gates so the agent works to a team's standards without the developer re explaining their stack each session. The site organizes the library as a searchable catalog and a cookbook of recipes. Examples include implementing a feature from idea to merged pull request with parallel agents, reviewing a pull request with specialized reviewers, fixing a GitHub issue with root cause analysis, running a parallel security audit across authentication, secrets, OWASP and dependencies, setting up a three tier memory that persists across sessions, and turning a Claude Design handoff URL into a reviewable pull request. The vendor says it also supports seven more coding agents. It runs locally inside Claude Code; it is not a hosted service and not editor autocomplete. Documentation is available in Markdown, with an OpenAPI specification, an MCP server and SDK packages. It is aimed at developers who already use Claude Code and want ready made workflows and guardrails. The vendor states that OrchestKit is free under the MIT license, with no paid tiers, usage limits or account. Claude Code and an Anthropic account are still needed to run the underlying agent, and that billing is separate.
