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.

Agent definitions record where they came from

Under the hood
Useful2 Signal2
Agents

Agents now record which source and file defined them, so extra-directory agents are labelled properly.

What

Agent entries now carry the source that declared them and the file they were declared in. An agent loaded from an extra search directory is labelled additionalDirectory, replacing an older check that guessed from the file shape and could report an unrecognised version.

Evidence

additionalDirectory

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