+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

+- You want Gemini chat sessions resumed across heartbeats with --resume
+- You want Paperclip skills available under the Gemini global skills directory
+
+Don't use when:
+- You need webhook-style external invocation (use http or openclaw_gateway)
+- You only need a one-shot script without an AI coding agent loop (use process)
+- Gemini CLI is not installed on the machine that runs Paperclip
+
+Core fields:
+- cwd (string, optional): default absolute working directory fallback for the agent process (created if missing when possible)
+- instructionsFilePath (string, optional): absolute path to a markdown instructions file prepended to the run prompt
+- promptTemplate (string, optional): run prompt template
+- model (string, optional): Gemini model id. Defaults to auto.
+- yolo (boolean, optional): pass --approval-mode yolo for unattended operation
+- command (string, optional): defaults to "gemini"
+- extraArgs (string[], optional): additional CLI args
+- env (object, optional): KEY=VALUE environment variables
+
+Operational fields:
+- timeoutSec (number, optional): run timeout in seconds
+- graceSec (number, optional): SIGTERM grace period in seconds
+
+Notes:
+- Runs use positional prompt arguments, not stdin.
+- Sessions resume with --resume when stored session cwd matches the current cwd.
+- Paperclip auto-injects local skills into "~/.gemini/skills" when missing.
+- Authentication can use GEMINI_API_KEY / GOOGLE_API_KEY or local Gemini CLI login.
