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 | $0.13095 | $0.13095 |
| Opus 5.5 | $0.05238 | $0.05238 |
| Sonnet 5.5 | $0.02619 | $0.02619 |
| Haiku 4.5 | $0.01310 | $0.01310 |
Grade C, and why
hera-agent-unity AGENTS.md scanned grade C with 2 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.

hera-agent-unity — Guide for AI Agents
You are an AI coding agent operating in a Unity project that has
hera-agent-unityavailable as a CLI. This document tells you how to use it efficiently. It is meant to be loaded into your project's rules file so every session has it without spending tokens to discover it.Where to put this content.
AGENTS.mdat the project root is the canonical cross-tool agent rules file, standardized by the Agentic AI Foundation (AAIF) under the Linux Foundation (Dec 2025) and adopted by 60,000+ open-source repositories. OpenAI Codex, Claude Code, Cursor, GitHub Copilot, Gemini CLI, and 30+ tools read this file by default.For multi-tool projects, the cleanest pattern is
AGENTS.mdas the single source of truth plus a one-line stub in tool-specific paths. Tool-specific files only matter when a tool requires a different format (Cursor's.mdcYAML frontmatter is the main case).Recommended layout — multi-tool projects:
- Drop the full guide (or its lean subset) into
AGENTS.mdat the project root.- For tools that need their own format, drop a short stub that defers to
AGENTS.md:
CLAUDE.md→> See AGENTS.md.(Claude Code readsAGENTS.mdnatively since late 2025).cursor/rules/hera-agent-unity.mdc→ frontmatter + the same body (Cursor also supports plainAGENTS.mdas a fallback).github/copilot-instructions.md→ repository-wide pointer toAGENTS.md(Copilot uses nearest-file precedence;.github/skills/is for Agent Skills)GEMINI.md+.agents/agents.md+.agents/skills/hera-agent-unity/SKILL.md→ AntiGravity project entry + workspace handoff + on-demand skill.continuerules→ identical bodyPer-tool target paths (2026-current):

hera-agent-unity is a CLI that drives a running Unity Editor over HTTP. Common uses: execute C# inside the Editor, read console logs, query the active scene, run tests, capture screenshots, batch several commands in one round-trip. Each call is a tool round-trip; response bytes become your input tokens, so reads cost as much as your own writes.

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.

hera-agent-unity AGENTS.md is an instructions file published in the GitHub repository NotNull92/hera-agent-unity (29 stars, last pushed today), licensed Apache-2.0. It adds 13,095 tokens to every session, about $0.0524 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
