Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00047 | $0.02710 |
| Opus 5 | $0.00023 | $0.01355 |
| Sonnet 5 | $0.00009 | $0.00542 |
| Haiku 4.5 | $0.00005 | $0.00271 |
Grade A, and why
stripe-link-cli 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 12d 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.
This is a copy
86% identical to stripe-link-cli — 59 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stripe Link CLI Skill
Wraps @stripe/link-cli so Hermes can complete purchases on the user's behalf using one-time-use virtual cards or Shared Payment Tokens (SPT). Every spend is gated by an in-app approval in the Link mobile/web app — Hermes cannot self-approve.
US-only at the moment (Link account requirement). Windows is not supported by the upstream CLI — this skill is gated [linux, macos].
When to Use
Trigger phrases:
- "buy X", "pay for X", "make a purchase", "complete checkout"
- "get me a card", "I need a payment method"
- "log in to Link", "connect my Link wallet"
- HTTP 402 response from a merchant API with
www-authenticate: ... method="stripe"
If the user wants a paid API call (HTTP 402, no checkout form), the card path is wrong — use SPT via this same skill, or hand off to the mpp-agent skill.
Prerequisites
- Node.js 20+ available on
PATH(node --version) - US-based (Link account requirement)
The Link account, payment method, and spend-approval app do NOT need to be set up before Hermes attempts to pay — the CLI walks the user through them on first run:
- A Link account at https://app.link.com — created/linked during first
link-cliauth - At least one payment method — added during first run at https://app.link.com/wallet
- The Link mobile/web app — opened to approve the first spend request when it's made
No env vars required — auth state is stored locally by the CLI under its own config directory.
Install
Install once, globally:
npm install -g @stripe/link-cli
Or invoke ad-hoc via npx @stripe/link-cli. The skill below uses the installed link-cli form.
How to Run
All commands run through the terminal tool. The CLI auto-detects non-TTY callers and emits compact toon output by default — fine for the model. Pass --format json if a step needs structured fields.
Discover commands: link-cli --llms-full.
Get a command's schema before invoking: link-cli <command> --schema.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
