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 | $0.00033 | $0.02300 |
| Opus 5 | $0.00016 | $0.01150 |
| Sonnet 5 | $0.00007 | $0.00460 |
| Haiku 4.5 | $0.00003 | $0.00230 |
Grade A, and why
wishlist-save-for-later 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 9d 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.

Wishlist / Save for Later
Overview
Implement persistent wishlists that survive browser sessions for both authenticated and guest users. Includes shareable wishlist links, back-in-stock email alerts for out-of-stock wishlist items, and move-to-cart flows. Guest wishlists stored in localStorage are merged with the server-side list on login.
When to Use This Skill
- When shoppers want to save items for future purchase but are not ready to buy
- When building a feature to reduce cart abandonment by offering "save for later" on cart items
- When implementing back-in-stock notifications for high-demand products
- When the brand's social/sharing strategy should include wishlist sharing
Core Instructions
Step 1: Determine the merchant's platform and choose the right approach
| Platform | Recommended Approach | Why |
|---|---|---|
| Shopify | Install Wishlist Plus (free tier) or Growave (from $9/mo, includes wishlist + loyalty + reviews) | Wishlist Plus is the most installed wishlist app on Shopify — adds heart buttons to product and collection pages, persistent wishlists for logged-in users, guest wishlist via browser storage, and a shareable wishlist page |
| WooCommerce | Install YITH WooCommerce Wishlist (free) — the most widely used WooCommerce wishlist plugin | YITH Wishlist adds an "Add to Wishlist" button to product pages, creates a shareable wishlist page for each customer, handles guest wishlists via session, and includes "move to cart" functionality |
| BigCommerce | Enable the built-in Wishlists feature in Account → Wishlists — it's native to the platform; extend with Wishlist Plus app if needed | BigCommerce includes server-side wishlists for registered customers built in; guests need a third-party app or custom solution |
| Custom / Headless | Build with localStorage for guest users + server-side storage for authenticated users; merge on login | Full control over data model, sharing, and back-in-stock notifications; see implementation below |

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.
