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 | $0.05377 | $0.05377 |
| Opus 5.5 | $0.02151 | $0.02151 |
| Sonnet 5.5 | $0.01075 | $0.01075 |
| Haiku 4.5 | $0.00538 | $0.00538 |
Grade A, and why
chrome-use 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 14d 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 — 444 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Instructions for AI coding agents working with this codebase.
Package Manager
This project uses pnpm. Always use pnpm instead of npm or yarn for installing dependencies, running scripts, etc. (e.g., pnpm install, pnpm run build).
Code Style
- Do not use emojis in code, output, or documentation. Unicode symbols (✓, ✗, →, ⚠) are acceptable.
- In documentation and markdown, never use double hyphens (
--) as a dash. Use an emdash (—) sparingly when needed. Prefer rewriting the sentence to avoid dashes entirely. - CLI colored output uses
cli/src/color.rs. This module respects theNO_COLORenvironment variable. Never use hardcoded ANSI color codes. - CLI flags must always use kebab-case (e.g.,
--auto-connect,--allow-file-access). Never use camelCase for flags (e.g.,--autoConnectis wrong).
Documentation
When adding or changing user-facing features (new flags, commands, behaviors, environment variables, etc.), update all of the following:
cli/src/output.rs—--helpoutput (flags list, examples, environment variables)README.md— Options table, relevant feature sections, examplesskill-data/core/SKILL.md(and itsreferences/) — so AI agents know about the feature when they load the core skill. Editskill-data/core/SKILL.mdfor overview/workflow changes; editskill-data/core/references/*.mdfor detailed reference content. Do not put feature content inskills/chrome-use/SKILL.md— that file is an intentionally thin discovery stub fornpx skills addand exists only to redirect agents tochrome-use skills get core.docs/*.htmland theirdocs/en/*.htmlmirrors — the docs site at chrome-use.leeguoo.com. These are hand-written static HTML, not a generator:docs/is Chinese,docs/en/is English, and both must be updated. A commit that touchesskill-data/prints a reminder naming the pages to update.README.mdandREADME.zh.md— both, for the same reason.- Inline doc comments in the relevant source files
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.
