CommandLayer SDK v1.1.0

CommandLayer SDK v1.1.0

First public release of the CommandLayer SDK.

CommandLayer turns agent actions into signed, verifiable receipts. This SDK is the primary entry point for developers to run actions and independently verify execution.

---

What’s included

• TypeScript SDK for running actions and verifying receipts
• Python SDK with matching verification behavior
• Canonical receipt verification (hash + signature + canonicalization)
• Cross-SDK parity (TypeScript and Python produce identical verification results)
• Commons vs Commercial request separation
• Node 20-safe test runner and SDK tooling

---

Contract behavior

• Commons requests do not include x402 metadata
• Commercial requests include x402 where required
• receipt_id is treated as an identifier (not enforced as hash equality)
• Verification requires:
  • canonicalization match
  • hash match
  • signature validity
  • algorithm match
  • required fields

npm install @commandlayer/sdk
