Atlas turns a stated need into a full system design by mining the Atlas knowledge graph. This is the Codex harness surface for the atlas plugin.

• Skills: atlas (the need → design brain) and atlas-graph-query (a reference for the Atlas MCP tool surface).
• Commands: /atlas:discover, /atlas:mine-processes, /atlas:mine-data, /atlas:collect-nuances — each delegates orchestration to the babysitter:babysit skill using an atlas-specific .a5c process.
• MCP: the Atlas knowledge-graph server (atlas), wired natively into Codex's own MCP config format.

The Atlas MCP server is wired natively for Codex — no manual setup. It defaults to https://atlas-staging.a5c.ai/api/mcp and is overridable at runtime via the ATLAS_MCP_URL environment variable. The mcp__atlas__atlas_public_* tools are then available to the atlas skills.

Atlas commands delegate orchestration to Babysitter, so install the Babysitter CLI once, then install this plugin for Codex:

npm install -g @a5c-ai/babysitter
babysitter harness:install-plugin codex
