Artifact Contract Auditor
Purpose: make each workspace auditable and shareable.
This skill checks two contracts:
- •Units contract: if a unit is marked
DONE, its required outputs must exist. - •Pipeline contract: the pipeline’s
target_artifacts(from the pipeline spec referenced byPIPELINE.lock.md) should exist for a complete run.
It always writes a report so workspaces can serve as regression baselines.
Inputs
- •
UNITS.csv - •
PIPELINE.lock.md - •Pipeline spec referenced by
PIPELINE.lock.md(underpipelines/*.pipeline.md; reads YAMLtarget_artifacts)
Outputs
- •
output/CONTRACT_REPORT.md
Workflow (analysis-only)
- •Read
UNITS.csvand validate DONE outputs
- •For every unit with
status=DONE, verify each required output exists. - •Outputs prefixed with
?are treated as optional and do not fail the contract.
- •Read
PIPELINE.lock.mdand validate pipeline target artifacts
- •Resolve the pipeline spec under
pipelines/*.pipeline.mdand loadtarget_artifactsfrom its YAML front matter. - •Resolve the pipeline spec path and load
target_artifactsfrom its YAML front matter. - •If the pipeline is complete (all units are
DONE/SKIP), verify each requiredtarget_artifactsfile exists.
- •Write
output/CONTRACT_REPORT.md(always)
- •Include missing DONE outputs (unit-level drift) and missing pipeline targets (pipeline-level completeness drift).
Status semantics
- •
PASS: pipeline complete (all unitsDONE/SKIP) AND all required target artifacts exist AND no DONE unit is missing required outputs. - •
OK: pipeline incomplete (still running) BUT DONE unit outputs are consistent; missing targets are expected. - •
FAIL: at least one DONE unit is missing required outputs OR pipeline is complete but required target artifacts are missing.
How to use this report (self-loop routing)
- •If DONE outputs are missing: fix the contract drift (regenerate the missing artifacts, or revert the unit status to TODO/BLOCKED).
- •If the pipeline is complete but target artifacts are missing: find which unit/skill owns each missing artifact and rerun that unit.
Script
Quick Start
- •
python .codex/skills/artifact-contract-auditor/scripts/run.py --workspace workspaces/<ws>
All Options
- •
--workspace <dir> - •
--unit-id <U###>(optional) - •
--inputs <semicolon-separated>(unused; runner compatibility) - •
--outputs <semicolon-separated>(unused; runner compatibility) - •
--checkpoint <C#>(optional)
Examples
- •End-of-run audit (recommended before sharing a workspace):
- •
python .codex/skills/artifact-contract-auditor/scripts/run.py --workspace workspaces/<ws>
