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.

Settings that fail validation are labelled

Under the hood
Useful2 Signal2
Settings

Rejected settings are tagged as invalid-setting so warnings can name where the bad value came from.

What

A setting rejected by validation is now attributed to an invalid-setting source instead of landing in the default bucket, so warnings can say where the bad value came from. Parent managed settings are also run through a validator that records their source.

Evidence

invalid-setting

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