Claude Code v2.1.219 ·

Advisor tool result payload is now a discriminated union that can be encrypted

Advisor tool results can come back encrypted with no text field, so reading .text may find nothing.

What

The advisor-tool docs warn that advisor_tool_result.content differs by advisor model, so code that reads .text unconditionally can silently get nothing.

Details
  • Plaintext advisors return advisor_result with text and stop_reason.
  • The newest advisors return advisor_redacted_result with encrypted_content and no text.
  • The executor-to-advisor compatibility table is expanded with the new Opus, Fable and Mythos IDs.
Evidence

advisor_redacted_result

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