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 | $0.00108 | $0.01211 |
| Opus 5 | $0.00054 | $0.00606 |
| Sonnet 5 | $0.00022 | $0.00242 |
| Haiku 4.5 | $0.00011 | $0.00121 |
Grade A, and why
fluentcart-coupons-discounts 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FluentCart coupons and discounts
Extend the calculation pipeline instead of altering displayed totals. Revalidate every coupon against current server-owned cart data.
Read coupon-pipeline.md before implementing a virtual coupon, new rule, custom type, or recurring discount.
Use the canonical model
Coupon stores code, type, amount, priority, status, stackable, show_on_checkout, dates, use_count, and JSON conditions. AppliedCoupon stores the order-time snapshot. Never reconstruct historical discounts from the currently editable Coupon.
Use CouponResource for admin CRUD because it validates and converts fixed amounts/limits. In 1.6.0:
- fixed amount uses integer minor units after formatting;
- percentage amount is a percentage value from 0 through 100;
- lower numeric priority applies first;
- multiple coupons survive together only under the stackability rules.
Extend eligibility
- fluent_cart/coupon/can_use_coupon: reject the whole coupon with false or WP_Error.
- fluent_cart/coupon/will_skip_item: exclude one item.
- fluent_cart/discount/pre_apply: transform candidate cart items before application; preserve complete shape and avoid price trust.
- fluent_cart/coupon/per_customer_usage_query: add legitimate usage scoping.
- fluent_cart/coupon/validating_coupon: normalize/admin-order validation code.
Keep eligibility callbacks pure. Coupon recalculation runs after cart/address/ shipping/tax changes and may run repeatedly.
Implement virtual coupons carefully
fluent_cart/coupon/resolve_coupons receives the database-found collection, requested codes, and cart context. Append an unsaved Coupon model for an addon-owned code only after server-side lookup and authorization.
add_filter(
'fluent_cart/coupon/resolve_coupons',
static function ($coupons, array $codes, array $context) {
// Resolve only this addon's opaque code from server-owned state.
// Append a fully populated unsaved Coupon model.
return $coupons;
},

What ships with it
2 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.

fluentcart-coupons-discounts is a skill published in the GitHub repository Lonsdale201/wp-agent-skills (22 stars, last pushed 2d ago), licensed MIT. It adds 108 tokens to every session and 1,211 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
