Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Make the command print only a JSON array of FunctionDeclarations (or {function_declarations:[...]}) to stdout, send logs to stderr, exit 0, and restart the CLI (setting requires restart).
Option: Make the command print only a JSON array of FunctionDeclarations (or {function_declarations:[...]}) to stdout, send logs to stderr, exit 0, and restart the CLI (setting requires restart). [evidence: official_recommended_action]
Applies when: Registering custom tools via tools.discoveryCommand / tools.callCommand
Steps:
1. Run the discovery command manually and pipe to `jq type` (should be "array").
2. Move logging to stderr.
3. Restart gemini after changes; use --debug to see discovery errors.
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
