$npx -y skills add WILLOSCAR/research-units-pipeline-skills --skill human-checkpointReview and record one pending human checkpoint in a research Workspace; use when a HUMAN Unit is blocked on an Approve C* decision, and never treat silence or artifact existence as approval.
| 1 | # Human Checkpoint |
| 2 | |
| 3 | A checkpoint is **consent**, not a formatting step. It binds a named human |
| 4 | Decision to the exact Artifacts and constraints reviewed before execution may |
| 5 | continue. |
| 6 | |
| 7 | ## Inputs |
| 8 | |
| 9 | - `DECISIONS.md`. |
| 10 | - `UNITS.csv` and `STATUS.md` for the active checkpoint. |
| 11 | - Artifacts declared by the locked Pipeline for that checkpoint. |
| 12 | |
| 13 | ## Outputs |
| 14 | |
| 15 | - Updated `DECISIONS.md`. |
| 16 | - A checkpoint Decision in the Run ledger. |
| 17 | |
| 18 | ## Steps |
| 19 | |
| 20 | ### 1. Identify the pending checkpoint |
| 21 | |
| 22 | Inspect `STATUS.md`, `UNITS.csv`, and the active runner message. Select the |
| 23 | first blocked HUMAN Unit and its `C*` identifier. If multiple checkpoints |
| 24 | appear active or the checklist is missing, stop and repair the projection |
| 25 | before approving anything. |
| 26 | |
| 27 | Completion criterion: exactly one pending checkpoint and its owning HUMAN Unit |
| 28 | are identified. |
| 29 | |
| 30 | ### 2. Review the declared Artifacts |
| 31 | |
| 32 | Read the locked Pipeline's checkpoint contract and inspect every named Artifact. |
| 33 | Record requested constraints or scope changes in the checkpoint block before |
| 34 | approval; do not silently modify reader-facing content as part of sign-off. |
| 35 | |
| 36 | Completion criterion: the reviewer can name the Artifacts inspected and any |
| 37 | constraints attached to the Decision. |
| 38 | |
| 39 | ### 3. Record approval through the adapter |
| 40 | |
| 41 | Use the Pipeline adapter so the Markdown checkbox and machine Decision ledger |
| 42 | remain synchronized: |
| 43 | |
| 44 | ```bash |
| 45 | uv run python scripts/pipeline.py approve \ |
| 46 | --workspace workspaces/<name> \ |
| 47 | --checkpoint <C*> |
| 48 | ``` |
| 49 | |
| 50 | Do not infer approval from chat silence, a completed Artifact, or an existing |
| 51 | but unchecked checklist item. |
| 52 | |
| 53 | Completion criterion: `DECISIONS.md` contains `[x] Approve C*` and the Run |
| 54 | ledger records `checkpoint.approved` for the same checkpoint. |
| 55 | |
| 56 | ### 4. Hand execution back to the Runner |
| 57 | |
| 58 | Resume through the Pipeline adapter. The Harness may complete the HUMAN Unit |
| 59 | and expose the next eligible Unit; this Skill does not execute downstream |
| 60 | semantic work itself. |
| 61 | |
| 62 | Completion criterion: the checkpoint is no longer the active blocker, or one |
| 63 | new specific blocker is visible in durable Workspace state. |
| 64 | |
| 65 | ## Context Pointers |
| 66 | |
| 67 | - The locked `pipelines/*.pipeline.md` owns checkpoint purpose and required |
| 68 | review Artifacts. |
| 69 | - `DECISIONS.md` is the human-readable Decision surface. |
| 70 | - `.harness/decisions.jsonl` is the machine-readable history; update it |
| 71 | through the adapter rather than by hand. |
| 72 | - Use `checkpoint-brief` to recreate a post-route checkpoint review block. |
| 73 | - `scripts/run.py` is a runner-compatibility helper that only toggles the |
| 74 | Markdown checkbox. Prefer `scripts/pipeline.py approve`, which also records |
| 75 | the machine Decision. |
| 76 | |
| 77 | ## Troubleshooting |
| 78 | |
| 79 | - If the approvals checklist is missing after C0, materialize the review block |
| 80 | with `checkpoint-brief` before approval. Use `pipeline-router` only for the |
| 81 | initial C0 route. |
| 82 | - If reviewed upstream Artifacts later change, expect the Harness to revoke the |
| 83 | stale approval and request a new Decision. |
