spec skillA

Name: spec
Author: squillo

spec is agent-read markdown (skill) from squillo/aph: APH (Agent per Human) protocol crash course and reference. Use when working with APH, NotarizationEnvelope JSON, envelope validation or verification, notarization flows, a Delegation Mandate or Communication Mandate, the notary service, the "agent driver's license" model, APH error codes (APH_E001..APH_E020), signing profiles (eddsa-jcs-2022, ecdsa-jcs-2019, detached JWS), notary public-key discovery (did:key, did:web, DNS TXT), channel kinds, or the A2A notarization extension. Also covers OPERA.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
