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 5.1 | $0.02523 | $0.02523 |
| Opus 5.5 | $0.01009 | $0.01009 |
| Sonnet 5.5 | $0.00505 | $0.00505 |
| Haiku 4.5 | $0.00252 | $0.00252 |
Grade A, and why
template-repo 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 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 — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This file provides guidance to AI agents (Cursor, Aider, and other AI coding assistants) when working with code in this repository.

Project Context
This is a single-maintainer project by @AndrewAltimit with a container-first philosophy:
- All Python and Rust operations run in Docker containers
- Self-hosted infrastructure for zero-cost operation
- Designed for maximum portability - works on any Linux system with Docker
- No contributors model - optimized for individual developer efficiency
- No external engagement - no feature requests, guidance, or community interaction accepted (legal protection due to dual-use codebase)
AI Agent Collaboration
Active agents (canonical roster: docs/agents/agent-matrix.md):
- Claude Code - Primary development assistant; runs the security and quality PR reviews
- OpenRouter - General PR review via Qwen (
qwen/qwen3.7-max) - OpenCode - Code generation via OpenRouter
- Crush - Code generation via OpenRouter
- GitHub Copilot - Review suggestions in PRs
Legacy / not allowed: Gemini (Google) and Codex (OpenAI). Their code stays in the repo but is unsupported and must not be enabled or used. Google dropped its AI Principles pledge against weapons and surveillance uses in February 2025; OpenAI partners with governments that conduct mass surveillance and enable autonomous weapons. See
docs/agents/agent-matrix.md#legacy-agents-gemini-and-codex-not-allowed.
For complete agent documentation, see docs/agents/README.md
AI Agent Security Model
- Keyword Triggers:
[Action][Agent]format (e.g.,[Approved][Claude]) - Allow List: Only pre-approved users can trigger agents
- Commit Validation: Prevents code injection after approval
- Implementation Requirements: Only complete, working code is accepted
For complete security documentation, see docs/agents/security.md
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.
