What
Two messages Claude receives now give more help:
Credential-store refusal: when the sandbox, the protected space commands run in, refuses a command that queries your system's password store, the message used to end at "Nothing was run." It now adds advice to split the command into simpler commands.
Unnamed downloads: when a file downloaded through a connector could not be given a proper name, the message now says where the whole file was saved, and that under that name a PDF or picture can't be opened as one.
Why
Claude gets clearer hints on how to recover, so it is more likely to try a working next step instead of getting stuck.
