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 | $0.03082 | $0.03082 |
| Opus 5 | $0.01541 | $0.01541 |
| Sonnet 5 | $0.00616 | $0.00616 |
| Haiku 4.5 | $0.00308 | $0.00308 |
Grade A, and why
simulator-ai-plugin AGENTS.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 — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for coding agents (Codex, Claude Code, etc.) working in the simulator-ai-plugin
repository. Humans: see the root README.md (usage) and
docs/ARCHITECTURE.md (design).
What this repo is
A plugin for Claude Code, Codex, and AWS Kiro that connects the Simulator.Company platform
(backend: pong-server / control-api) to the host via MCP. It bundles:
- a Go MCP server (
plugins/simulator/mcp-server/) that exposes the Simulator/papi/1.0public API as a curated, typed set of ~95 MCP tools (declared in Go, not a generic spec passthrough), scoped to the core scenarios; - 14 skills (
plugins/simulator/skills/) — markdown that teaches the model the platform's entity model and common workflows.
Read docs/ARCHITECTURE.md before making non-trivial changes.

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.
