An artifact manager for system specifications.
This project is an MCP server that you can use to manage different specification artifacts — see Concepts for the full list of artifact types and how they relate, and MCP Server / docs/MCP.md for the tool/resource/prompt reference.
The MCP server (and the management CLI) are optional. You install them as "extras" (see Installation).

Concepts
Every artifact is a plain markdown file with a YAML frontmatter block on disk — git-friendly, diffable, and readable/editable by hand. The filesystem is always the source of truth; the MCP server wraps it with structured, validated read/write/list/status tools (see Usage).
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
