What is agent-toolkit AGENTS.md?

A project guide for Sanity, a content management system for storing and editing structured website content. It lists commands for connecting AI editors, managing schemas and types, running the editor, and deploying projects.

Use it when configuring Sanity access, changing content schemas, generating TypeScript types, developing the Studio, or deploying infrastructure and sites.

It helps coding agents choose the right Sanity command and follow the project's setup, content, and deployment process.

Token cost

What it costs to keep this loaded

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	$0.02500	$0.02500
Opus 5	$0.01250	$0.01250
Sonnet 5	$0.00500	$0.00500
Haiku 4.5	$0.00250	$0.00250

Measured 2d ago against content hash 214852505f4e, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

agent-toolkit 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 2d 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.

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.
