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.

Built-in skills can be registered disabled

Under the hood
Useful2 Signal3
Skills

The claude-api and Chrome skills can be registered without being invocable.

What

The claude-api skill and the Chrome browser skill now accept a disabled option, letting a caller register them without making them invocable. The Chrome skill keeps its existing feature checks behind that switch.

Evidence

isEnabled: () => !e

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