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 | $0.17161 | $0.17161 |
| Opus 5 | $0.08580 | $0.08580 |
| Sonnet 5 | $0.03432 | $0.03432 |
| Haiku 4.5 | $0.01716 | $0.01716 |
Grade A, and why
agents-shipgate 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 today.
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 — 930 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agents Shipgate · Agent Instructions
Authoritative instructions for AI coding agents (Claude Code, Codex, Cursor, Aider, Cline, Windsurf, Devin, or any other harness — see docs/agents/any-coding-agent.md) working with this repository or a project that uses Agents Shipgate.
If you are a human, the README and the wiki are the right places to start. This file is optimized for agent ingest: short, copy-pasteable, machine-friendly.
What this project is
The deterministic merge gate for AI-generated agent capability changes. Reads shipgate.yaml plus tool sources (MCP exports, MCP server source (TypeScript/Go registration idioms), OpenAPI specs, OpenAI Agents SDK Python files, Anthropic Messages API tool/prompt artifacts, Google ADK Python/config files, LangChain/LangGraph Python files, CrewAI Python files, OpenAI API artifacts, Codex repo config, Codex plugin packages and marketplaces, n8n workflow JSON/stubs, Conductor OSS workflow JSON) and produces deterministic findings. Local-first and static by default — no agent execution, tool calls, LLM calls, or network access.
- Inputs: MCP · MCP server source · OpenAPI · OpenAI Agents SDK · Anthropic Messages API · Google ADK · LangChain/LangGraph · CrewAI · OpenAI API · Codex config · Codex plugin · n8n · Conductor OSS workflow JSON
- Outputs: Markdown · JSON · SARIF
- Trust: Static-by-default. No agent execution, tool calls, LLM calls, or network access.
- Marketing site: threemoonslab.com — human-readable companion pages. If you are an agent working inside this repo, use the in-tree
.well-known/agents-shipgate.json(currentmaincontract, may be ahead of the site's released copy) for schema-version and gating-signal decisions.
Naming (canonical)
Use exactly one form depending on context. Mixing them in user-visible copy is an adoption cost.
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.

agents-shipgate AGENTS.md is an instructions file published in the GitHub repository ThreeMoonsLab/agents-shipgate (87 stars, last pushed today), licensed Apache-2.0. It adds 17,161 tokens to every session, about $0.0858 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 2026-08-30.
