When Claude Code's advisor feature is activated with a custom model that isn't in its capability table, it now emits a visible warning with guidance.
Details
Warning: "Warning: Advisor disabled — base model <name> isn't in the advisor capability table. Switch to a public model alias (opus, sonnet, fable) or set CLAUDE_CODE_ENABLE_EXPERIMENTAL_ADVISOR_TOOL=1."
This replaces a silent failure
