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 | $0.00077 | $0.03008 |
| Opus 5 | $0.00039 | $0.01504 |
| Sonnet 5 | $0.00015 | $0.00602 |
| Haiku 4.5 | $0.00008 | $0.00301 |
Grade A, and why
kinde-billing 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.
How it starts
The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kinde Billing
Produces a billing contract: customer type, environment, Stripe mode, currency, billing admin, plan group and table, features and charges, trials and tax, portal, entitlements, usage reporting, webhooks, lifecycle policies, and control planes. Consume the kinde-b2b tenant contract; do not invent a second tenancy model.
Stance
Treat the run as design-only until the user authorizes a mutation. Default to a non-production Kinde environment and Stripe test mode. Dated sources and first-party conflicts live in REFERENCES.md. Read it before relying on a product claim that is not already recorded in a sibling file, and whenever two official pages disagree.
Actively invoke the loaded framework adapter for framework work. If none is available, mark implementation blocked. Keep this contract API-neutral.
Vocabulary
Use these names; do not collapse them.
| Term | Means |
|---|---|
| Plan group | Organization-type or user-type catalog. Never mixed. |
| Plan | Published or draft package of charges and features. |
| Feature | Unmetered gate or metered unit. Shared key, per-plan price/limit. |
| Pricing table | Customer-facing comparison. One group, max four plans. |
| Customer | Billing identity (customer_… / billing_customer_id). |
| Agreement | Subscription (agreement_…). |
| Entitlement | Configured plan access or unit limit, not current consumption. |
High-impact
Without explicit authorization, record these as planned: production Stripe connection, first plan publish (locks currency), live price change, cancellation or refund, and meter write. Apply only an explicitly authorized item and capture observed evidence. Work other setup in test.
Verified Management surface
Scopes and bodies are in RUNTIME.md and EVENTS.md. Recheck REFERENCES.md and the published OpenAPI before acting:

What ships with it
7 files 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.
