Agent Skill Identity (ASI) v0.1 — Reference SDK

⚠️ ASI v0.1 is a cryptographic identity primitive. It does not implement reputation, governance, or registries.

Minimal, framework-agnostic cryptographic identity primitives for agent skill ecosystems.

This repo contains a TypeScript/JavaScript (Node) reference implementation and tests for:

• Skill publisher authenticity (bundle signing + verification)
• Skill bundle integrity (manifest file inventory + hashes)
• Runtime agent identity verification (invocation envelopes)

Status

Draft v0.1 (February 2026)

Guarantees

• No remote calls
• All operations are local

Crypto + canonicalization

• SHA-256 via @noble/hashes
• JCS (RFC 8785) via canonicalize
