Sirius Keeps Coding-Agent Knowledge in the Repo

Why it surfaced

Its pitch is unusually concrete: one Docker command, plain Markdown with YAML frontmatter, real-time indexing, and support for six programming ecosystems. Sirius also knows what it is arguing against, calling itself neither a wiki, a SaaS product, nor “another AGENTS.md that outgrew itself.”

Sirius is a local MCP server that turns project architecture, business rules, decisions, and components into git-versioned documentation that coding agents can query.
