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.

Tool blocks now also match the older tool name a wrapper stands in for.

What

The lists of blocked and gated tools are compared against both a tool's own name and the name of the older tool it wraps, so a wrapper cannot slip past a block written for the original.

Evidence

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