operator-cpu

operator-cpu is a skill for Claude Code from projectcpu/project-cpu-mcp. It costs 30 tokens per session (1,203 once invoked), scanned A, original, MIT.

Instructions for operating or explaining a Project CPU game session through its MCP server, a connection that lets an AI agent read game data and perform supported actions. They define the game's cells, resources, buildings, processes, ownership, and decision workflow.

In plain words
What is it for?
Use them to inspect the game world, compare strategies, check costs, prepare transactions, carry out game actions, and verify the resulting state.
Why use it?
They tell the agent to use the live game rules and current state before acting, reducing mistakes involving prices, limits, resources, or ownership.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

operator-cpu scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project CPU

Load cpu_persona first. Authenticate for owner-scoped reads and actions. Use cpu_get_game_config as the live rulebook, then read only relevant state. Tool descriptions and results define current rules, prices, limits, and errors.

While cpu_onboarding reports the onboarding unfinished, walk the player through it before anything else: keep each step to four or five sentences, use only that step's own terms, close a step that is pure explanation at once and deliver the next brief in the same reply, and end on a call to action only where the step needs something from the player.

Use a decision loop: observe, compare, quote or preflight, act, verify. The Operator sets the objective, spend, and risk. Present relevant trade-offs without assuming an optimization target. Refresh state after a transaction or meaningful delay.

Game model

  • Cells and ownership — the world is a finite sphere of Cell NFTs. A Cell can hold deposits, one building, a Warehouse, a Mode, a Process, and inbound Deliveries. This state follows the NFT; wallet ETH and $CPU do not.
  • Reveal and resources — Reveal draws deposits and costs live ETH and $CPU. Raw-resource reservoirs are finite and closed: consumed raw material returns for later Reveals. Buildings and Recipes produce refined resources and wCPU.
  • Buildings and Processes — a building must become Ready. Extractors mine deposits, crafters run Recipes, and an Active hub enables routing and resource trade. Mode selects output and may cost $CPU to change. A Process commits the Cell for bounded Batches and cannot be cancelled. Crafting takes inputs up front; mining draws from deposits as Cycles settle. Claim an ended Process to free its slot.
  • Warehouse pressure — each resource has an Effective cap. Full means the Warehouse reached it. A Process Stalls when less than one Cycle of output fits. Responses include crafting, selling, withdrawing wCPU, or moving inventory.
  • Logistics — Route endpoints are owned revealed Cells. Intermediate waypoints may be Virgin cells, owned Cells, or Active hubs. Other foreign revealed Cells are walls. cpu_route_network exports the endpoint components from the complete map; cpu_next_hops gives a one-hop view of the same map. Transport submits one complete Route. A quote reserves nothing. Finalize an arrived Delivery before using its cargo.
  • Internal resource market — Active hubs host Lots of Warehouse resources priced in $CPU. Buying creates a Fill and Delivery; selling escrows resource units and may require Transport to the Hub. Hub Sale fees, Transit fees, and Syndicate economics apply.
  • External Cell market — OpenSea orders trade whole Cell NFTs in the configured settlement currency. Actions bind to an exact orderHash; marketplace and creator fees apply, and the Cell's game state follows its ownership.
  • Production objective — Recipe chains can produce wCPU at a CPU Forge. cpu_withdraw converts it into wallet $CPU while emission budget remains and may return a Partial tranche. The shared reserve is finite.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

operator-cpu is a skill published in the GitHub repository projectcpu/project-cpu-mcp (1 stars, last pushed 13d ago), licensed MIT. It adds 30 tokens to every session and 1,203 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
