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 | $0.00063 | $0.01141 |
| Opus 5.5 | $0.00025 | $0.00456 |
| Sonnet 5.5 | $0.00013 | $0.00228 |
| Haiku 4.5 | $0.00006 | $0.00114 |
Grade A, and why
agent-rules 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md Generator Skill
Generate and maintain AGENTS.md files following the agents.md convention. AGENTS.md is FOR AGENTS, not humans.
When to Use
- Creating or updating AGENTS.md for new/existing projects
- Standardizing agent documentation across repositories
- Checking if AGENTS.md files are current with recent code changes
- Onboarding AI agents to an unfamiliar codebase

Workflow
- Detect:
detect-project.sh+detect-scopes.shto identify stacks and subsystems - Extract:
extract-commands.sh,extract-ci-rules.sh, etc. to gather facts - Generate:
generate-agents.shwith--style=thin(default) or--verbose - Verify:
verify-content.sh+verify-commands.sh-- MANDATORY before done
Use --update to preserve human-curated content outside <!-- GENERATED --> markers.
Core Principles
- Structured over Prose -- tables parse faster than paragraphs
- Never Fabricate -- only document what exists; verify every command and path
- Pointer Principle -- point to files, don't duplicate content
- Auto Symlinks -- CLAUDE.md/GEMINI.md symlinks by default (see
ai-tool-compatibility.md)
What ships with it
60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
- 1mo ago First seen · 84 lines · 63 tokens per session scan A c450539f8d90
agent-rules is a skill published in the GitHub repository dirien/yet-another-agent-harness (20 stars, last pushed 4mo ago), licensed MIT. It adds 63 tokens to every session and 1,141 once invoked, about $0.0003 per session on Opus 5.5. 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.
