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.

Named errors for skill search, message sending and image resizing

Under the hood
Useful2 Signal2
Error Handling

Skill search, message sending and image resizing failures now raise distinguishable named errors.

What

Three failure paths now raise errors with explicit names instead of generic ones: plugin skill lookup when search is unavailable, message sending when preconditions are unmet, and image resizing. Failures in these areas are now distinguishable rather than surfacing as an unnamed error.

Evidence

PluginSkillSearchUnavailableError

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.
