Use the Gemini CLI to consult Gemini and delegate coding tasks for prototyping, debugging, and code review. Supports multi-turn sessions via SESSION_ID. Optimized for low-token, file/line-based handoff.

Tokens, turns and time describe resource use, not a dollar price.
One of 12 test cases the skill fixed. Same model, same prompt, with and without the skill.
We want to invoke the Gemini bridge to analyze `server/db.ts` using a custom model name 'gemini-1.5-pro-experimental'. What command-line flag is used to specify this model?
| Checked | Without skill | With skill |
|---|---|---|
| Passes --model gemini-1.5-pro-experimental to scripts/gemini_bridge.py. | Missed | Passed |
The instructions your model reads when the skill loads.
Use Gemini CLI as a collaborator while keeping Codex as the primary implementer.
Host note: this skill is written for a Codex host. When running in another host (e.g., Claude Code), adapt Codex-specific details such as the command-runner timeout and upload paths.
This skill provides a lightweight bridge script that returns structured JSON and supports multi-turn sessions via SESSION_ID.
gemini directly; always use the bridge script (scripts/gemini_bridge.py) so output/session handling stays consistent.--cd set to the repo root (it sets the gemini process working directory). Use --cd "." only if your CWD is the repo root.SESSION_ID and reuse it for follow-ups to keep the collaboration conversation-aware.timeout_ms to 600000 (10 minutes) unless a shorter/longer timeout is explicitly required.--sandbox to run Gemini in sandbox mode.⚠️ If your prompt contains Markdown backticks (`like/this`), do not pass it directly via --PROMPT "..." (your shell may treat backticks as command substitution). Use a heredoc instead; see references/shell-quoting.md.
