Unclear Whether the message also appears in the interactive terminal interface is not settled.
What
Some plugins provide a language server, a helper program that understands a programming language and gives Claude Code code information. When one fails to start, Claude Code now builds a message that says which case it is:
The program could not be found.
The program exists but is not allowed to run.
Some other failure.
The message points to claude --debug or the Errors tab in /plugin, and suggests disabling the plugin if you do not need it. In stream-json output it is sent as a warning notification, and in plain text output it is printed.
Why
A broken language server plugin now comes with a hint about how to fix it instead of failing quietly.
