Format

Source URL + ?hs=gz. + base64url of the content. Gzip compression is enabled by default (prefix gz.). Content is free (Markdown, SQL, YAML, HTML, text) and so is the license. The Agent Skills format is recommended but not required.

Traceability

The SHA-256 hash of source URL + content serves as a trace. Each version can reference the previous version's hash. Recommended, not required.

Signature

The author can sign the hash. Ed25519 recommended.

Size

The maximum size of the hs parameter depends on the browser:

Chrome        ~32 000 caractères / characters
Firefox       ~65 000 caractères / characters
Safari        ~80 000 caractères / characters
Edge          ~32 000 caractères / characters
Android       ~8 000 caractères / characters

The analyser_amendements recipe from tricoteuses is 4,895 bytes raw, 6,528 characters in base64url. It fits in all modern browsers. With compression enabled by default (prefix gz., or br. for brotli), skills of 250-500 KB fit in ~32,000 characters.
