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.

Slash command registration (search for name: "simplify", "Review changed code for reuse, quality, and efficiency")

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