ChangesSection of the release

The shell command explanation system has been refactored from structured outputs to a tool-based approach.

Details
  • Now uses explain_command tool with explicit JSON schema
  • Cleaner separation between explanation, reasoning, and risk assessment
  • Simplified system prompt: "Analyze shell commands and explain what they do, why you're running them, and potential risks."
Evidence

zE5 at line 2256 (tool definition, contains "explain_command")

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