Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.07871 | $0.07871 |
| Opus 5 | $0.03936 | $0.03936 |
| Sonnet 5 | $0.01574 | $0.01574 |
| Haiku 4.5 | $0.00787 | $0.00787 |
Grade A, and why
fak 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 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.
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 — 378 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — orientation for coding agents
Not the human contributor guide. This file is operating instructions for automated contributors working inside the maintainers' shared checkout — trunk guards, lane leases, commit trailers, and shared-tree rules that have no meaning outside it. If you are a human evaluating or contributing to fak, read
README.mdfor what fak is andCONTRIBUTING.mdfor how to contribute; nothing below is required of you.
You are an autonomous agent working in this repo. This file is the machine-read entry point (the agents.md convention). It is intentionally command-dense and free of philosophy. For the why, read
README.md; for a curated doc map, readllms.txt. Humans: seeSTART-HERE.md.
Default scope when launched from this repo
When an agent is launched with this fak repository as its working directory,
default all broad or underspecified work requests to FAK work in this
repository. Requests such as “finish local WIP,” “work the backlog,” or “run
agents all night” mean inspect, prioritize, implement, test, and ship FAK work;
they do not authorize a workspace-wide sweep of sibling repositories.
Use FAK's guarded headless-agent and worker mechanisms for parallel or unattended work, following the lane, lease, worktree, landing, and witness rules below. Only inspect or modify another repository when the operator explicitly names that repository or the FAK task itself has a concrete, evidenced cross-repo dependency. If scope is ambiguous, stay in FAK.
Delegate real work; keep the coordinator context clean
Use guarded headless agents or an equivalent isolated worker for every substantive unit of work. The primary agent is the coordinator: decompose the request, give each worker a bounded goal and distinct file set, preserve only decisions and compact evidence in the primary context, and independently witness worker results before landing or reporting them. Delegate investigation, implementation, tests, long command output, and independent review; do not pull their full transcripts into the coordinator.
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.

fak AGENTS.md is an instructions file published in the GitHub repository anthony-chaudhary/fak (36 stars, last pushed today), licensed Apache-2.0. It adds 7,871 tokens to every session, about $0.0394 per session on Opus 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 2026-09-03.
