Install what you bought

First purchase from a seller

Buy on the listing page with your email.
On any machine:

npx allodic add https://their.site/s/the-skill

Enter the email you paid with → a one-time code arrives → enter it. The device stores a token for that seller; you won't be asked again.

The CLI verifies the release signature, pins the seller's key, installs to your agents (Claude Code, Cursor, …), and prints where.

Everything after that

npx allodic update          # pull entitled updates for everything installed
npx allodic verify <url> --evals   # re-run the seller's benchmarks yourself
npx allodic inspect <url>   # read the neutral preview before buying

The rules, plainly

Licenses are per-skill. A second skill from the same seller installs with zero friction after you buy it — but only after.
Per-device activation. New laptop → same 30-second email+code dance.
Full refund = access ends. Downloads and updates stop for that skill; your other purchases are untouched. A partial goodwill refund does not end access. What's already on disk stays — possession is DRM-free; acquisition is what's gated.
Key pinning. If a seller's signing key ever changes, updates refuse loudly until you decide to trust it. That's a feature.
Use your payment email. Activation matches your license by the email Stripe saw. Different email → "no license found."
