File contents

Gemini CLI Runtime Contract

This skill defines how to call the gemini-companion.mjs runtime from Claude Code agents and commands.

Primary entry point

node "${CLAUDE_PLUGIN_ROOT}/scripts/gemini-companion.mjs" task "<prompt and flags>"

Rescue agent rules

One Bash call to gemini-companion.mjs task. Return stdout verbatim — no commentary.
Do NOT call review, challenge, status, result, or cancel from consult.
May use gemini-prompting skill ONLY to shape the prompt before forwarding.

Flag handling

Flag	Behavior
`--model <alias>`	Passed through to companion; alias resolution happens inside
`--effort <level>`	Reserved for future use (not yet supported by Gemini CLI)
`--resume-last`	Resumes latest Gemini session thread
`--write`	Enables write mode (`--yolo` inside companion)
`--background` / `--wait`	Strip these — consult always runs foreground
`--resume` / `--fresh`	Strip these routing flags; use `--resume-last` instead

Default behavior

Default --write unless user explicitly asks for read-only.
Do not add --background — consult runs synchronously.
Do not interpret or summarize Gemini output — return it verbatim.
