Human Checkpoint (HITL sign-off)

Goal: make human approvals explicit and auditable, so downstream units can safely proceed.

This skill is intentionally simple: it standardizes how a human signs off in DECISIONS.md.

Inputs

Required:

• DECISIONS.md

Optional:

• UNITS.csv (to confirm which checkpoint is currently blocked, e.g., C1/C2)
• STATUS.md (to confirm the current checkpoint)

Outputs

• DECISIONS.md (updated checkbox + short sign-off note)

Procedure

1. Identify the blocked checkpoint

   • Check the runner message (or STATUS.md), or inspect UNITS.csv for the first owner=HUMAN unit that is BLOCKED.

2. Open DECISIONS.md and find the approvals checklist

   • Look for a line like: - [ ] Approve C2 ...

3. Review the artifacts required by that checkpoint

   • The pipeline doc (pipelines/*.pipeline.md) usually lists what to review (e.g., protocol, outline, module plan).
   • If the checkpoint block is missing, add a short checklist into DECISIONS.md (what you reviewed).

4. Approve

   • Tick the checkbox: - [x] Approve C*
   • Append a short note under the checkpoint block (recommended):
     • Date
     • Artifacts reviewed
     • What you approved + constraints (if any)
     • Signed by

Acceptance

• The correct Approve C* checkbox in DECISIONS.md is ticked ([x]).
• Any added sign-off note does not silently expand scope or contradict the run goal.

Troubleshooting

The approvals checklist is missing in DECISIONS.md

Fix:

• Run pipeline-router for the relevant checkpoint block, or add a minimal block manually:

## Approvals (check to unblock)
- [ ] Approve C2
