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 | $0.00418 | $0.00418 |
| Opus 5.5 | $0.00167 | $0.00167 |
| Sonnet 5.5 | $0.00084 | $0.00084 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
cursor-os 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.
What it actually says
AGENTS.md — cursor-os
This repository ships Cursor OS — an installable operating layer that makes Cursor project-aware. It dogfoods its own contract: the rules below govern work in this repo.
What this project is
- An installable operating layer, not a framework. Keep the file set small and purposeful.
- The core promise: make Cursor project-aware by installing a contract, rules, memory docs, and prompts.
- The two highest-value assets are
template/AGENTS.md(the portable engineering contract) andtemplate/prompts/localize-cursor-os.md(the localization prompt). - Prefer practical, repo-specific guidance over generic process text.
Repository layout
template/— the kit that gets copied into other projects. Never assume a specific stack here.scripts/— the CLI and install/doctor APIs (init.mjs), read-only project detection (detect.mjs), and smoke test. Node built-ins only; no dependencies.examples/— concrete examples showing what localization looks like.docs/— this repo's own decision log (not installed into user projects).README.md,CHANGELOG.md,CONTRIBUTING.md— public-facing docs.
Working agreements
- Keep template files framework-neutral. Stack-specific guidance is generated during localization, not shipped as blanks.
- The installer must stay dependency-free and idempotent: never overwrite a user's existing files.
- Do not refer to prompts by number or sequence. Always use the full file path (e.g.,
prompts/plan-feature.md). - When you change the template's file set, update
README.md,CHANGELOG.md, and the installer's EXPECTED list inscripts/smoke-test.mjstogether. - Validate
package.jsonparses and runnpm test(the smoke test) before claiming the installer works.

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.

cursor-os AGENTS.md is an instructions file published in the GitHub repository KingEmma7/cursor-os (2 stars, last pushed 1mo ago), licensed MIT.
