Security

Grade A, and why

shippo 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 2d 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.

  "description": "Shippo connects you to USPS, UPS, FedEx, DHL, and 40+ carriers, so you can handle a shipment end to end right inside Claude. Compare live rates and pick the cheapest or best option, buy and print labels (domestic and international, with customs declarations), validate and standardize addresses, and track packages across carriers. Just ask in plain language: rate-shop a parcel, buy the right label, check a delivery status, or confirm an address before you ship. Whether you run a store or just need to send a package, Shippo turns a pile of carrier accounts into one simple conversation.",

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.
