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.

Skill tool description collapsed to one string

Skills

The Skill tool prompt is now one block and no longer says coordinator use is read-only.

What

The Skill tool prompt is now a single block, and the coordinator-only paragraph saying a coordinator's use is read-only (no fork, no permission grants, no hooks, no shell commands) is no longer part of this definition. Whether that text moved elsewhere in the build is not visible here.

Evidence

Only names from the listing (or that the user typed explicitly) are valid.

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

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
