What is coupon-promotion-audit?

A review of Stripe coupons and promotion codes, including active discounts, redemptions, and their effect on subscription revenue. Coupons define discounts, while promotion codes are codes customers can enter to receive them.

Use it to list active coupons and codes, count discounted subscriptions, estimate their MRR impact, and flag potentially costly discount arrangements.

It shows which discounts are still active, how widely they are used, and where long-term discounts may reduce revenue.

Per session 47 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 316 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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	$0.00047	$0.00316
Opus 5.5	$0.00019	$0.00126
Sonnet 5.5	$0.00009	$0.00063
Haiku 4.5	$0.00005	$0.00032

Security

Grade A, and why

coupon-promotion-audit 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 2mo 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.
