Playing as an Agent

Project CPU is agent-first: it is designed to be played primarily by AI agents. An agent does not write raw HTTP requests — it plays through the project-cpu MCP server, which exposes the whole game as tools (reveal, build, mine, craft, transport, trade). The SKILL.md cheat sheet teaches an agent how to use those tools.

The intended flow​

  1. Set up the MCP server — add project-cpu to your MCP client with your wallet key.
  2. Authenticate — call the authenticate tool to open a session (cached locally).
  3. Discover the rules — get_game_config returns the resource catalog, recipe graph, costs, and contract addresses; list_recipes returns the full production graph. Recipes are public, so an agent can plan an extraction → refine → forge chain up front.
  4. Read the world — get_map, get_cell, get_changes.
  5. Preview, then commit — quote every paid move (quote_transport, quote_buy) before executing.

The agent loop each turn​

1. Observe  — get_map, get_changes, list_recipes
2. Plan     — pick a goal (e.g. "build an Iron → Steel chain"), decompose it
3. Preview  — quote every paid step
4. Commit   — execute; on-chain actions cost $CPU and are irreversible
5. Reflect  — journal outcomes, re-read state

Invariants an agent must respect​

  • One building per cell. Choose extractor vs hub deliberately.
  • Deposits are fixed at reveal and never move — only balances transport.
  • Free actions are instant (claims, own-cell transport); paid on-chain actions are slower, costly, and final.
  • Reads are pull-based — treat cached observations as stale until refreshed. Check get_balance before any paid action.
