Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00952 | $0.00952 |
| Opus 5 | $0.00476 | $0.00476 |
| Sonnet 5 | $0.00190 | $0.00190 |
| Haiku 4.5 | $0.00095 | $0.00095 |
Grade A, and why
gameforge CLAUDE.md 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 2d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
General Guidelines for working with Nx
- For navigating/exploring the workspace, invoke the
nx-workspaceskill first - it has patterns for querying projects, targets, and dependencies - When running tasks (for example build, lint, test, e2e, etc.), always prefer running the task through
nx(i.e.nx run,nx run-many,nx affected) instead of using the underlying tooling directly - Prefix nx commands with the workspace's package manager (e.g.,
pnpm nx build,npm exec nx test) - avoids using globally installed CLI - You have access to the Nx MCP server and its tools, use them to help the user
- For Nx plugin best practices, check
node_modules/@nx/<plugin>/PLUGIN.md. Not all plugins have this file - proceed without it if unavailable. - NEVER guess CLI flags - always check nx_docs or
--helpfirst when unsure
Scaffolding & Generators
- For scaffolding tasks (creating apps, libs, project structure, setup), ALWAYS invoke the
nx-generateskill FIRST before exploring or calling MCP tools
When to use nx_docs
- USE for: advanced config options, unfamiliar flags, migration guides, plugin configuration, edge cases
- DON'T USE for: basic generator syntax (
nx g @nx/react:app), standard commands, things you already know - The
nx-generateskill handles generator discovery internally - don't call nx_docs just to look up generator syntax
GameForge Project Context
GameForge is an AI-powered game creation platform. Circle 1 MVP is a locally-run builder where users chat with an AI agent team (Designer, Developer, QA) to collaboratively build Phaser 2D games with live preview.

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.

gameforge CLAUDE.md is an instructions file published in the GitHub repository robcost/gameforge (2 stars, last pushed 6mo ago), licensed MIT. It adds 952 tokens to every session, about $0.0048 per session on Opus 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.
