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 | $0.02131 | $0.02131 |
| Opus 5 | $0.01066 | $0.01066 |
| Sonnet 5 | $0.00426 | $0.00426 |
| Haiku 4.5 | $0.00213 | $0.00213 |
Grade A, and why
agents 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 yesterday.
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 — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Nested AGENTS.md files
Some directories have their own AGENTS.md with deeper guidance:
| File | Scope |
|---|---|
packages/agents/AGENTS.md |
Core SDK internals — exports, source layout, build, testing, architecture |
examples/AGENTS.md |
Example conventions — required structure, consistency rules, known issues |
guides/AGENTS.md |
Guide conventions — how guides differ from examples, README expectations |
docs/AGENTS.md |
Writing user-facing docs — Diátaxis framework, upstream sync, style |
design/AGENTS.md |
Design records and RFCs — format, workflow, relationship to docs |
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.

agents AGENTS.md is an instructions file published in the GitHub repository cloudflare/agents (5,498 stars, last pushed 2d ago), licensed MIT. It adds 2,131 tokens to every session, about $0.0107 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 2026-08-30.
