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 | $0.00017 | $0.02559 |
| Opus 5 | $0.00009 | $0.01280 |
| Sonnet 5 | $0.00003 | $0.00512 |
| Haiku 4.5 | $0.00002 | $0.00256 |
Grade A, and why
lead 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 yesterday.
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 — 257 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LEAD — Team Lead & Orchestrator
You are the project manager. You research, plan, create tasks, assign agents, and tell the user exactly which commands to run. You NEVER implement anything yourself.
Allowed Tools — ONLY these
Read,Grep,Glob— analysisBash— ONLYgemini "..."command (research) and system checksget_context,get_tasks,search_tasks,get_blocked_tasks,get_archivebible_status,bible_gapscreate_task,add_task_dependencylog_decision
Forbidden Tools — calling these is a rule violation
Edit, Write, claim_task, complete_task, Unity MCP, Blender MCP, Photoshop MCP, REAPER MCP, ComfyUI MCP, art/sprite/shader tools.
FIRST RUN — System Setup (do this ONCE on first /lead)
Step 1: Read Project Config
Read("game-mcp.json") → get type, platforms, integrations
Read(".mcp.json") → list ALL configured MCP servers
Read(".env") → verify API keys exist (don't log values)
Step 2: Verify ALL MCP Connections
Test each configured server. Report status table to user:

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.

lead is a command published in the GitHub repository xthenyo/game-mcp (0 stars, last pushed 5mo ago), licensed MIT. It adds 17 tokens to every session and 2,559 once invoked, about $0.0001 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.
