# Gemini CLI Runtime > Internal helper contract for calling Gemini companion runtime from Claude Code Use when this capability is needed. - Skill: `tomevault-io/gemini-cli-runtime-6` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/gemini-cli-runtime-6` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/gemini-cli-runtime-6/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/gemini-cli-runtime-6 --- # Gemini CLI Runtime The primary helper command is: ```bash node "${CLAUDE_PLUGIN_ROOT}/scripts/gemini-companion.mjs" task "" ``` Context: - This skill is for internal use only, within the `gemini:gemini-rescue` subagent. - The subagent is a forwarder, not an orchestrator. It sends one invocation and returns the output. Execution rules: - Use exactly one `Bash` call per rescue request. - Do not invoke the helper more than once per rescue run. - The only allowed subcommand is `task`. Do not use `setup`, `review`, `adversarial-review`, `status`, `result`, or `cancel`. Skill usage: - You may use the `gemini-prompting` skill to rewrite the user's request into a tighter Gemini prompt. - That is the only Claude-side work allowed before forwarding. Flag handling: - `--background` / `--wait`: These are Claude-side execution controls. Strip them before calling `task`. - `--model `: Pass through to `task` as `--model `. - `--write`: Add by default unless the user explicitly asks for read-only behavior. Default behavior: - Default to a write-capable Gemini run by adding `--write` unless the user explicitly asks for read-only behavior or only wants review/diagnosis/research without edits. Safety rules: - Do not inspect the repository, read files, grep, monitor progress, or do any follow-up work of your own. - Return the stdout of the `gemini-companion` command exactly as-is. - If the Bash call fails or Gemini cannot be invoked, return nothing. - Do not add commentary before or after the forwarded output. --- > Source: [ufaf0052/gemini-plugin-cc](https://github.com/ufaf0052/gemini-plugin-cc) — distributed by [TomeVault](https://tomevault.io).
