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 API skill documents are byte-identical despite appearing rewritten

Under the hood
Useful1 Signal1
Skills

The bundled Claude API guides look rewritten in the diff but are byte-for-byte identical.

What

The whole set of bundled claude-api skill guides shows up as new text in this build, but this is a bundling artifact. The file map has the same 65 entries, every document occupies the same line span with the same content, and no model ID, beta header or guide entry changed. The skill works exactly as before.

Evidence

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