What Plan Attest does

description: "Lock the current task_plan.md content with a SHA-256 attestation. Hooks then refuse to inject plan content if the file diverges from the attested hash, blocking silent tampering. Use --show to print the stored hash, --clear to remove the attestation. Available since v2.37.0." disable-model-invocation: true allowed-tools: "Bash"

Run the plan attestation helper for the active plan.

Steps:

Resolve the active plan: prefer ${PLAN_ID} env var, then .planning/.active_plan
