Excerpt

verify-witness

Codex skill: Ed25519 witness manifest verification for a scaffolded harness.

What it does

Reads .harness/witness.json, validates the Ed25519 signature against the embedded public key, and reports VALID / INVALID with a one-line reason.

Distinct from validate-harness:

validate-harness is the umbrella — doctor + verify + path-guard + mcp + secrets
verify-witness is only the signature check — fast yes/no for CI / federation handshakes / multi-signer workflows

Usage from Codex

/verify-witness
/verify-witness path=./my-harness
/verify-witness path=./my-harness strict=false

Equivalent CLI

harness verify ./my-harness

Why it's separate from validate-harness
