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 | $0.01047 | $0.01047 |
| Opus 5.5 | $0.00419 | $0.00419 |
| Sonnet 5.5 | $0.00209 | $0.00209 |
| Haiku 4.5 | $0.00105 | $0.00105 |
Grade A, and why
stripekit 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.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for AI agents working on the stripekit codebase. (To learn how to use stripekit in a project, read SKILL.md or llms.txt instead.)
What this is
stripekit is the "create-next-app of Stripe": a CLI that reconciles a declarative stripe.config.ts into the user's own Stripe account and scaffolds correct billing code. It is a tool, not a platform — no hosted service, no runtime dependency in generated code. See README.md and DESIGN.md for the full picture.
Layout

Setup & commands
Node 20+ and pnpm. From the repo root:
pnpm install
pnpm -C packages/stripekit build # bundle CLI + types (tsup)
pnpm -C packages/stripekit test # vitest
pnpm -C packages/stripekit typecheck # tsc --noEmit
pnpm format # prettier
pnpm docs:build # build the docs site
Always run test, typecheck, and format before committing.
Releasing
stripekit is published to npm. Keep one version number across packages/stripekit/package.json, src/constants.ts (VERSION), docs/public/.well-known/mcp/server-card.json, server.json, .claude-plugin/plugin.json, and .claude-plugin/marketplace.json.
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.

stripekit AGENTS.md is an instructions file published in the GitHub repository rafaelcg/stripekit (2 stars, last pushed 2mo ago), licensed MIT. It adds 1,047 tokens to every session, about $0.0042 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
