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 | $0.02179 | $0.02179 |
| Opus 5.5 | $0.00872 | $0.00872 |
| Sonnet 5.5 | $0.00436 | $0.00436 |
| Haiku 4.5 | $0.00218 | $0.00218 |
Grade B, and why
Agent AGENTS.md scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
The repo itself is the framework. Consumers `git clone` it and run `setup.sh` to install configs into their AI runtime (`~/.claude/`, `~/.codex/`, and with `--antigravity` `~/.gemini/config/plugins/`) and optionally scaf How it starts
The opening of the file, as written. The whole thing — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This file follows the agents.md spec so any AI coding agent (Codex CLI, OpenAI Assistants, Cursor, etc.) can understand how to work in this repo.
For Claude Code, see also CLAUDE.md (if present) or use this file as the primary instructions.
For Antigravity CLI (agy), see also GEMINI.md (if present) or use this file.
What this repo is
An AI-agnostic agent framework: rules, hooks, agents, skills, and automation with shared policy across Claude Code / Codex CLI / Antigravity CLI.
Runtime enforcement coverage differs; see docs/cross-runtime-harness-design.md.
The repo itself is the framework. Consumers git clone it and run setup.sh to install configs into their AI runtime (~/.claude/, ~/.codex/, and with --antigravity ~/.gemini/config/plugins/) and optionally scaffold a target project.
Operating mode for AI agents working IN this repo
When an AI agent works on improving the framework itself (this repo, not a consumer project):
1. Plan before code
For any change touching 3+ files or any change to core/hooks/, adapters/, or rules/: write a plan to /tmp/agent-plan-<slug>.md before editing. Discuss tradeoffs with the user before implementation.
2. Sanitize discipline
This repo MUST stay domain-neutral. The original maintainer ported it from a prior domain-specific project (the v0 mirror of it is preserved on the archive/v0-mirror tag, out of the shipped tree; later trim snapshots stay under legacy/). Before committing any file under core/, rules/, agents/, skills/, templates/, docs/, or root:
# Run the sanitize audit — must return zero matches outside legacy/
bash core/tests/sanitize-audit.sh
The audit script greps for known domain taint patterns (prior project name, prior-project domain terms, prior-project absolute paths) and machine-identity PII (real home paths, Apple .local device hostnames — see rules/public-repo.md § Machine-identity PII). The pattern list lives in core/tests/sanitize-audit.sh — update it if you introduce a new project-specific term that needs guarding.
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.

Agent AGENTS.md is an instructions file published in the GitHub repository joymin5655/Agent (2 stars, last pushed today), licensed MIT. It adds 2,179 tokens to every session, about $0.0087 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
