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 | $0.02498 | $0.02498 |
| Opus 5.5 | $0.00999 | $0.00999 |
| Sonnet 5.5 | $0.00500 | $0.00500 |
| Haiku 4.5 | $0.00250 | $0.00250 |
Grade A, and why
AgentFS 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 — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AgentFS — Instructions for AI Agents
This file contains instructions for AI agents (Claude Code, Cursor, OpenClaw, etc.) working on the AgentFS project.
Project Overview
AgentFS is a CLI tool (npx create-agentfs) that scaffolds an Obsidian vault as a filesystem-based operating system for AI agents. The core concept: a .agentos/ kernel space serves as single source of truth and compiles into native agent config formats.
Status: v0.1.4 — All 13 epics implemented (Phases 1–11 complete). See docs/architecture.md for the full spec.

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 · 223 lines · 2,498 tokens per session scan A d860a25f4167
AgentFS AGENTS.md is an instructions file published in the GitHub repository kksudo/AgentFS (2 stars, last pushed 6mo ago), licensed MIT. It adds 2,498 tokens to every session, about $0.0100 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 2026-08-31.
