+
+Use when:
+- You want Paperclip to run the Gemini CLI locally on the host machine
+- You want Gemini chat sessions resumed across heartbeats with --resume
+- You want Paperclip skills injected locally without polluting the global environment
+
+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.
+- approvalMode (string, optional): "default", "auto_edit", or "yolo" (default: "default")
+- sandbox (boolean, optional): run in sandbox mode (default: false, passes --sandbox=none)
+- 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/\` via symlinks, so the CLI can discover both credentials and skills in their natural location.
+- Authentication can use GEMINI_API_KEY / GOOGLE_API_KEY or local Gemini CLI login.
