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 | $0.00031 | $0.00199 |
| Opus 5 | $0.00015 | $0.00100 |
| Sonnet 5 | $0.00006 | $0.00040 |
| Haiku 4.5 | $0.00003 | $0.00020 |
Grade A, and why
shop scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Shop
Use MnemoPay's commerce tools for autonomous shopping with escrow protection.
Available MCP tools:
shop_search— search for products by queryshop_buy— purchase a product (uses escrow for protection)shop_orders— list current orders and their statusshop_confirm_delivery— confirm delivery and release escrowshop_set_mandate— set spending limits and approval thresholds
When the user wants to shop:
- Use
shop_searchto find products matching "$ARGUMENTS" - Present options with prices
- If the user confirms, use
shop_buyto purchase - Explain the escrow protection (funds held until delivery confirmed)
For purchases above the mandate threshold, explain that approval is needed.
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.

shop is a skill published in the GitHub repository mnemopay/mnemopay-sdk (8 stars, last pushed 21d ago), licensed Apache-2.0.

No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
