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 | $0.00898 | $0.00898 |
| Opus 5 | $0.00449 | $0.00449 |
| Sonnet 5 | $0.00180 | $0.00180 |
| Haiku 4.5 | $0.00090 | $0.00090 |
Grade B, and why
agent-instructions-kit AGENTS.md scanned grade B with 1 finding 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 6d 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.
Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Mission
A small CLI + GitHub Action that helps repos maintain consistent, safe agent instruction files (AGENTS.md, CLAUDE.md). Lints for dangerous patterns, scores quality, and generates templates informed by Karpathy's principles and real-world data from 2,500+ repos. Deliberately simple — no over-engineering.
Stack
TypeScript / Node.js. Bundled with @vercel/ncc. Tested with Vitest. Linted with ESLint 10 (flat config).

Core principles
- Think before coding — clarify assumptions before writing code. Don't silently pick an interpretation.
- Simplicity first — implement the simplest solution. No premature abstractions, no config options nobody will use.
- Surgical changes — only modify what's necessary. Don't refactor surrounding code or "clean up" unrelated files.
- Verify, don't trust — run
npm testandnpm run typecheckbefore declaring any task complete.
When to stop and ask
- The task requires adding a new dependency
- You're unsure which approach to take among multiple valid options
- The change would affect the public CLI or Action interface
- Something feels wrong or requirements seem contradictory
- Proceed without asking for: bug fixes, test additions, documentation updates, and changes with one obvious implementation
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.

agent-instructions-kit AGENTS.md is an instructions file published in the GitHub repository malmichaels-gif/agent-instructions-kit (2 stars, last pushed 1mo ago), licensed MIT. It adds 898 tokens to every session, about $0.0045 per session on Opus 5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
