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 errors get a cleaner, session-aware message

You'll notice
Useful3 Signal2
Slash Commands

Failed slash commands show a cleaner summary, and cancelling now just says Interrupted.

What

When a slash command or a skill fails, the message you see is now a sanitized summary rather than the raw error text, and cancelling shows "Interrupted" instead of an error. On some connection types the detail is logged rather than shown, and you get a note that it was withheld.

Details
  • Applies to both the command's captured error output and the warning shown when a stacked skill fails.
  • Not behind a feature flag; the withholding branch depends on the kind of session, not a setting you can change.
Evidence

failed (detail withheld on this connection)

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