title: Gemini Local
summary: Gemini CLI local adapter setup and configuration
---
The `gemini_local` adapter runs Google's Gemini CLI locally. It supports session persistence with `--resume`, skills injection, and structured `stream-json` output parsing.
## Prerequisites
- Gemini CLI installed (`gemini` command available)
- `GEMINI_API_KEY` or `GOOGLE_API_KEY` set, or local Gemini CLI auth configured
## Configuration Fields
| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `cwd` | string | Yes | Working directory for the agent process (absolute path; created automatically if missing when permissions allow) |
| `model` | string | No | Gemini model to use. Defaults to `auto`. |
| `promptTemplate` | string | No | Prompt used for all runs |
| `instructionsFilePath` | string | No | Markdown instructions file prepended to the prompt |
| `env` | object | No | Environment variables (supports secret refs) |
| `timeoutSec` | number | No | Process timeout (0 = no timeout) |
| `graceSec` | number | No | Grace period before force-kill |
| `yolo` | boolean | No | Pass `--approval-mode yolo` for unattended operation |
## Session Persistence
The adapter persists Gemini session IDs between heartbeats. On the next wake, it resumes the existing conversation with `--resume` so the agent retains context.
Session resume is cwd-aware: if the working directory changed since the last run, a fresh session starts instead.
If resume fails with an unknown session error, the adapter automatically retries with a fresh session.
## Skills Injection
The adapter symlinks Paperclip skills into the Gemini global skills directory (`~/.gemini/skills`). Existing user skills are not overwritten.
## Environment Test
Use the "Test Environment" button in the UI to validate the adapter config. It checks:
- Gemini CLI is installed and accessible
- Working directory is absolute and available (auto-created if missing and permitted)
- API key/auth hints (`GEMINI_API_KEY` or `GOOGLE_API_KEY`)
- A live hello probe (`gemini --output-format json "Respond with hello."`) to verify CLI readiness
