# grimoire

A package manager for AI-agent configuration that installs skills, rules, agents and MCP servers into Claude Code, Copilot, Cursor, Codex, Gemini, Zed, Amp, Kiro, Junie and opencode, storing packages on any OCI registry with no separate service to run.

grimoire declares a skill, rule, agent or MCP server once and writes it into whichever coding agents and editors a user has, each in that client's own format, pinned by digest in a lockfile. Storage is any OCI registry, such as GHCR, Docker Hub or a private one, so there is no Grimoire service to sign up for, and where a client has no honest way to receive an artifact, grim says so and skips it rather than writing configuration that looks installed but does nothing.

grim init creates a grimoire.toml, grim add declares, locks and installs a package from a registry reference, grim install re-materializes everything after a fresh clone, and a terminal UI browses the index. A search index is a plain directory of pointers into registries that can be scaffolded and hosted on GitHub or GitLab Pages with one command, giving a searchable catalog and a contribution gate that refuses a pull request claiming a namespace it does not own, again with no index server, database or account required.

Built with Rust, installed through a one-line shell or PowerShell installer, prebuilt binaries, a GitHub Action, or cargo install. Apache-2.0 licensed; stabilizing toward a 1.0 release.
