Skill Metadata

Name
artifact-contract-auditor
Description
Audit one research Workspace for declared Unit outputs and Pipeline target Artifacts, writing `output/CONTRACT_REPORT.md`; use for mid-Run coverage snapshots or final delivery completeness, not deep provenance integrity.

Artifact Contract Auditor

This Skill measures coverage: whether files promised by Units and the locked Pipeline exist at the point they are required. It does not replace the deeper Attempt, Manifest, Artifact-hash, and ledger checks in pipeline.py audit.

Inputs

  • UNITS.csv.
  • PIPELINE.lock.md.
  • The locked pipelines/*.pipeline.md target-Artifact contract.

Outputs

  • output/CONTRACT_REPORT.md.

Steps

1. Resolve the active contracts

Read PIPELINE.lock.md, resolve the Pipeline inside this repository, and parse UNITS.csv. Treat an invalid lock or malformed Unit table as a reportable contract failure rather than guessing another Workflow.

Completion criterion: one Pipeline contract and one readable Unit table are bound to the audit.

2. Check completed Unit outputs

For every DONE Unit, verify each required output exists. Outputs prefixed with ? are optional. A missing required output is Unit-level contract drift even when the Pipeline is still running.

Completion criterion: every DONE Unit is classified as output-complete or is listed with each missing required path.

3. Check final Pipeline targets when applicable

Determine whether all Units are terminal (DONE or SKIP). Only then require every non-optional target Artifact declared by the Pipeline. During a partial Run, report missing final targets as expected rather than failures.

Completion criterion: final-target completeness is evaluated against the actual Run phase, not merely file absence.

4. Write the report

Always write output/CONTRACT_REPORT.md with one status:

  • PASS: terminal Run, complete Unit outputs, complete Pipeline targets.
  • OK: partial Run, consistent completed Unit outputs.
  • FAIL: missing output from a DONE Unit, or missing final target from a terminal Run.

Completion criterion: the report names the evaluated Pipeline, Run phase, status, and every blocking missing path.

5. Route the next action

For missing Unit outputs, reopen or rerun the owning Unit through the Pipeline adapter. For missing final targets, identify the owning Unit or Skill. When file coverage passes, use scripts/pipeline.py audit for provenance integrity.

Completion criterion: every FAIL item has an owner and repair route; a PASS claim is explicitly limited to declared file coverage.

Context Pointers

  • The locked Pipeline front matter is the only source for target Artifacts.
  • UNITS.csv is the only source for Unit output obligations.
  • Use the deep Run Audit for Attempt pairing, Manifest identity, hashes, Decisions, Failures, and Evaluation consistency.

Script

Quick Start

uv run python .codex/skills/artifact-contract-auditor/scripts/run.py \
  --workspace workspaces/<name>

All Options

  • --workspace <path>: Workspace to audit.
  • --unit-id <U###>, --inputs, --outputs, --checkpoint: optional Pipeline-runner compatibility arguments.

Examples

Inspect the interface:

uv run python .codex/skills/artifact-contract-auditor/scripts/run.py --help

Run the deeper provenance audit after coverage passes:

uv run python scripts/pipeline.py audit --workspace workspaces/<name>

Side Effects

The audit may create or replace output/CONTRACT_REPORT.md. It must not edit research content, Unit statuses, checkpoint approvals, or source Artifacts.
