DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.203

Artifact Listing: Strict Input Validation

action: "list" now enforces that no publish-related fields are present:

  • If any field other than action or limit is set, the tool returns an error: ` action "list" takes only limit — remove <fields>. To publish or update an artifact, omit action. `
  • Passing limit with a publish action now returns an error: ` limit applies only to action "list" `
Evidence

Artifact list validation (search for 'action "list" takes only \limit\')

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
