Beyond the object itself, an Art Bulletin argument rests on documentary and material evidence: archives, inventories, contracts, letters, sale records, provenance chains, and technical/conservation findings. This skill governs how you gather, weigh, and cite that evidence so an expert reviewer trusts it. The looking lives in artbull-visual-analysis; here you handle everything else.
Artbull Evidence And Sources is a community-contributed Claude Code skill in the content-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/artbull-evidence-and-sources/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when assembling and handling the non-visual evidence for an Art Bulletin article — objects, archives, primary documents, provenance, and technical findings — and citing them rigorously. Art-historical claims must rest on verifiable sources, not assertion.
