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 | $0.00056 | $0.01627 |
| Opus 5 | $0.00028 | $0.00813 |
| Sonnet 5 | $0.00011 | $0.00325 |
| Haiku 4.5 | $0.00006 | $0.00163 |
Grade C, and why
stripe scanned grade C with 3 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 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
- **Body encoding: `application/x-www-form-urlencoded` — NOT JSON.** `curl -d "key=value"` sets this; a JSON body returns 400. Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
**Do NOT suggest editing `~/.claude/settings.local.json` manually.** The `teleport-setup add-key` command handles it with backup, validation, and masked input. Stop execution until the user has run the command and restar Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **Body encoding: `application/x-www-form-urlencoded` — NOT JSON.** `curl -d "key=value"` sets this; a JSON body returns 400. How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stripe
Direct REST access to Stripe's billing surface. Prefer this over training memory for real lookups/mutations, and over the Dashboard for scripted ops.
Usage
- Use for: Querying customers/charges, running refunds, creating PaymentIntents or Checkout Sessions, listing subscriptions/invoices.
- Skip for: Pricing strategy advice, SCA/3DS concept explanations, debugging stripe-node SDK errors (use Context7), tax rate questions.
Credentials check
[ -n "${STRIPE_API_KEY:-$STRIPE_SECRET_KEY}" ] && echo "STRIPE_API_KEY: PRESENT" || echo "STRIPE_API_KEY: MISSING"
Never echo the variable directly — the value would appear in the conversation transcript. Use only the boolean pattern above.
If MISSING, respond to the user with EXACTLY this message (do NOT paraphrase, do NOT suggest manual JSON edits):
I need your stripe credential. Run this in another terminal — it'll open the signup page, validate format, and save it safely with masked input:
teleport-setup add-key stripeThen restart Claude Code (
/exit, thenclaude) and ask me again.
Do NOT suggest editing ~/.claude/settings.local.json manually. The teleport-setup add-key command handles it with backup, validation, and masked input. Stop execution until the user has run the command and restarted.
Test vs. live: sk_test_... is sandbox; sk_live_... moves real money. Before destructive ops, check echo "${STRIPE_API_KEY:0:8}" and confirm intent.
API
- Base URL:
https://api.stripe.com/v1· Auth:Authorization: Bearer $STRIPE_API_KEY. - Body encoding:
application/x-www-form-urlencoded— NOT JSON.curl -d "key=value"sets this; a JSON body returns 400. - Pin
Stripe-Versionon every request (e.g.2026-03-25.dahlia) — unset floats to the account default and can drift. - Nested params use brackets:
metadata[order_id]=123,payment_method_types[]=card,line_items[0][price]=price_X. - Idempotency:
Idempotency-Key: <uuid>on POSTs that shouldn't double-execute. TTL ≥24h, per-account, test/live independent. Same key + different body →idempotency_error(not a silent swap). - Pagination is cursor-based:
starting_after={last_id}/ending_before=(object IDs, not offsets);limitmax 100. Rate limits ~100 req/s live, ~25 req/s test (Search 20/s).
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.

stripe is a skill published in the GitHub repository mnlt/teleport (8 stars, last pushed 4mo ago), licensed MIT. It adds 56 tokens to every session and 1,627 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 3 findings (sends data to an external url, reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
