A set of tools for reading Stripe account information and performing confirmed subscription cancellations. Stripe is a payment platform used to manage online payments and recurring billing.

Use it to check balances, payment intents, and subscriptions, and to prepare or cancel a subscription after confirming the target, timing, and billing impact.

It helps an agent answer operational billing questions while limiting financial changes through previews and explicit confirmation.

Install

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.

Any agent

npx skills add magnus919/agent-skills --skill stripe

Clone the repo

git clone --depth 1 https://github.com/magnus919/agent-skills

Made for: Claude Code, Codex.

Its marketplace also offers this one on its own, as the plugin stripe — /plugin install stripe after adding the marketplace above.

Token cost

What it costs to keep this loaded

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	$0.00116	$0.02109
Opus 5.5	$0.00046	$0.00844
Sonnet 5.5	$0.00023	$0.00422
Haiku 4.5	$0.00012	$0.00211

Security

Grade A, and why

stripe 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 20d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (tests/test_stripe_cli.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Stripe Operations

Use this skill to read Stripe account state and, with explicit confirmation, perform guarded mutations: account balance, payment intents, subscriptions, and subscription cancellation. This is a tool skill for the Stripe platform. Building Stripe payments into an application is integration development; this skill owns the everyday agent workflow: answering "what is our balance?", "which payments succeeded?", "what subscriptions are active?", and applying a confirmed cancellation.

Operating contract

Read-only first. Balance, payment, and subscription queries run freely and never change anything. The bundled stripe-cli script's primary surface is these reads.
Guard every mutation. State-changing operations — canceling a subscription — require an explicit human directive plus --dry-run preview and --yes confirmation through stripe-cli. Cancellations are financial actions with billing consequences: confirm the subscription, the timing, and the impact before acting.
Respect bounded reads. Stripe paginates with limit and has_more; never page past what the task needs. stripe-cli --limit caps every listing.
Keep evidence bounded. Quote short IDs, amounts, and statuses; never dump full API keys, customer data, or raw payloads into chat. Amounts are formatted by currency and JSON retains the raw integer and currency for audit.
Treat money data as sensitive. Balances, payments, and subscription details are financial records; quote only what the question needs and never expose full card or customer data.

The stripe-cli script

scripts/stripe-cli is an agent-first, stdlib-only CLI over the Stripe API. It is read-only-first: balance, payments, and subscriptions are the primary surface; the only mutation is guarded.

stripe/scripts/stripe-cli --help                          # no key or network needed
stripe/scripts/stripe-cli --json balance show
stripe/scripts/stripe-cli --json --limit 20 payments list
stripe/scripts/stripe-cli --json --limit 20 subscriptions list
stripe/scripts/stripe-cli --json subscriptions get --id sub_123
stripe/scripts/stripe-cli subscriptions cancel --id sub_123 --dry-run   # preview

Changes

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.
