Source Intelligence

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 v2.1.246

Softer fallback when no artifact types are published

Under the hood
Useful1 Signal1
Artifacts

With no artifact types published, Claude just builds what you asked for as normal.

What

When the list of artifact types is empty or unavailable, the model is told to make the thing the way it otherwise would, and only if the user actually asked for something, replacing the previous instruction to build the artifact itself as usual.

Details
  • Prompt text only; no behaviour outside what the model reads.
Evidence

If the user wanted something made, make it the way you otherwise would.

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