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 | $0.02116 | $0.02116 |
| Opus 5 | $0.01058 | $0.01058 |
| Sonnet 5 | $0.00423 | $0.00423 |
| Haiku 4.5 | $0.00212 | $0.00212 |
Grade A, and why
ai-expo-starter-template 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 9d 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.

description: globs: alwaysApply: true
Development cycle
- Run
pnpm install(you have full internet access) - Make your code edits and changes
- Finally run
pnpm ai:check(this will runtypecheck,test,fix, andlint)
Notes
- If there are any Typescript linting errors, run
pnpm fixbefore attempting to fix the errors yourself. - Never try to start a dev server - prompt the user to do this.

Code Conventions
When writing or modifying code in this project, please adhere to the following conventions:
- TypeScript Best Practices: Follow standard, idiomatic TypeScript coding practices for structure, naming, and types, unless otherwise overridden.
- Minimal Comments: Avoid adding comments unless they explain complex logic or non-obvious decisions. Well-written, self-explanatory code is preferred. Do not add comments that merely restate what the code does.
- Tests as Documentation: Rely on comprehensive tests (which will be added later if not present) to document the behavior and usage of the code, rather than extensive comments within the code itself.
- File naming conventions: Use kebab-case when naming directories, TypeScript, and other files.
- Type checking: after major modifications run
pnpm typecheckand fix any errors. - Open-source conventions Pretend you are writing code for a open-source project. Write best-in-class code.
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.
