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 | $0.00100 | $0.01248 |
| Opus 5 | $0.00050 | $0.00624 |
| Sonnet 5 | $0.00020 | $0.00250 |
| Haiku 4.5 | $0.00010 | $0.00125 |
Grade A, and why
fluentcart-downloads-storage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FluentCart downloads and storage
Separate file metadata, commercial entitlement, signed delivery, and download accounting. Possession of a path, download ID, or signed URL must not create a new entitlement.
Read download-delivery.md before generating links, changing access rules, or implementing a driver.
Preserve the delivery chain
Use ProductDownload records to map product/variation availability to driver metadata. Use Order::getDownloads() or the customer-profile flow to obtain entitled files. Generate delivery links with Helper::generateDownloadFileLink($download, $orderId).
For customer delivery always include the qualifying order ID. The helper signs download_identifier, valid_till, and order_id. FileDownloader then validates signature/time, successful payment, a matching product post on one supplied order, subscription access validity, and the final can_be_downloaded filter before dispatching to the storage driver.
Do not:
- expose Local file paths, S3/R2 keys, bucket names, or raw file_url values;
- build signed query strings manually;
- use the admin preview's order-less link as a customer entitlement link;
- cache signed URLs beyond their validity;
- assume a successful order grants every variation's files.
Do not assume the active route enforces limits or login
The customer-profile listing is login/customer scoped before it generates the URL. The resulting 1.6.0 signed URL is bearer authorization: FileDownloader does not re-check the current WP user and does not enforce the configured download_limit/download_expiry or update fct_order_download_permissions.
CustomerHelper contains limit/expiry/accounting code and DownloadService registers a fluent_cart/before_download_check_permission_and_store_log listener, but the active FileDownloader path does not emit that action in the tested source. Treat OrderDownloadPermission accounting as unwired for this route until a runtime test proves otherwise.
If the addon promises download limits, a customer-bound link, or single-use delivery, implement an addon-owned atomic claim before issuing/streaming the file and then delegate to the storage layer. Protect concurrent clicks and do not increment a count merely for rendering a link. Re-audit core after upgrade so enforcement is not accidentally duplicated.
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-downloads-storage is a skill published in the GitHub repository Lonsdale201/wp-agent-skills (22 stars, last pushed 2d ago), licensed MIT. It adds 100 tokens to every session and 1,248 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.
