artifact-validator

Validate one or more workflow artifacts (Markdown) against the fixed skeleton and the citation rules. This skill is read-only: it never edits artifacts, it only reports findings so the coordinator can map failures to agents.

What to check

Run every check below against each artifact file. Report each check as PASS or FAIL with concrete findings (quote the offending lines).

Structure (backs gate G8)

1. The file starts with a single # title line.
2. - **Owner agent:** <agent> is present and matches the artifact ownership table in CLAUDE.md (artifact filename ↔ agent name).
3. Sections exist, in this order, each as ## : Inputs used, Summary, Details, Costs, Sources, Open issues.
4. ## Costs is either a table (| Item | Unit | Qty | Unit cost | Total | Source / basis |) or the exact sentence No costs in this artifact.
5. ## Open issues contains at least one bullet, or None.
6. ## Sources contains at least one bullet unless the artifact is explicitly marked Not applicable (then it must state the reason).

Citations (backs gates G7 and G3)

7. Every source bullet has the shape - <Page title> — <URL> (fetched YYYY-MM-DD; supports: <claims>).
8. URLs are real pages: https:// or http://, no placeholders (example.com, localhost, TODO, ...), no invented patterns.
9. Every named venue, caterer, provider, price or weather figure in Details/Costs traces to a claim in a Sources bullet. A recommendation without a source is a FAIL.
10. Prices must come from a source or be marked price on request with the estimate basis stated. Unmarked, unsourced prices are a FAIL.

Ownership and safety

11. The artifact does not claim work owned by another agent (e.g. a venue artifact containing a full timeline).
12. Nothing in the artifact asks anyone to write output/event-plan.html or approval.json — those are forbidden outside html-builder / /approve-event.

How to report

Produce a compact report, one line per check:

<artifact> C1 PASS ... C12 PASS
<artifact> C9 FAIL — "Koneser Hall" has no source citation → responsible: venue-planner

End with OVERALL: PASS or OVERALL: FAIL — <responsible agents>. On FAIL, the coordinator applies the retry policy (see CLAUDE.md §6): re-run only the responsible agent with these findings, regenerate downstream dependents, re-validate.
