Plugin Eval

Eval --verbose now writes traces to the debug log instead of streaming them live.

Verbose trace logging for the early-access plugin eval command, readable via --debug-file.

--verbose--debug-fileplugin eval
What

--verbose on the plugin eval subcommand no longer streams the trace as it runs; it logs per-message trace events to the debug log and points at --debug-file for reading them. The plugin eval command is in early access.

Usage
claude plugin eval --verbose --debug-file trace.log
Evidence

Log per-message trace events to the debug log (use --debug-file to read them)

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