Execute prompts as the Gemma seat through the shared pi-runner implementation. This replaces the previous Cline-backed shim — --provider openrouter --model google/gemma-4-31b-it is pinned on every invocation, so the seat no longer depends on whichever provider Cline's mutable state happens to point at; the model that answers is always the forwarded Gemma model, served via OpenRouter.
Default Model
google/gemma-4-31b-it, pinned as--provider openrouter --model google/gemma-4-31b-iton every run. Override with--modelto point the Gemma seat at a different OpenRouter model id.
Prerequisites
piCLI installed and inPATH(npm install -g @mariozechner/pi-coding-agent)OPENROUTER_API_KEYin the environment (or an OpenRouter credential in Pi's auth store)
Security Model
This skill delegates to pi-runner, so it has the same execution and data sharing model as the Pi wrapper — see ../pi-runner/SKILL.md. Runs are hermetic (no extensions, skills, or AGENTS.md/CLAUDE.md discovery). Analysis roles (every role except implementer) default to read-only mode (only Pi's file-reading tool enabled). Pass --allow-write to opt out, or --no-tools to block tools entirely.
Shared Wrapper Reference
Supported options, roles, the --json output envelope key contract, return codes, and gotchas are identical to the shared wrapper — read shared/references/runner-common.md for the shared flags, envelope keys, return codes, and the seat-fidelity rule. The envelope is produced by pi-runner/scripts/run_pi.py with runner=gemma, effective_runner=pi, effective_provider=google (inferred from the google/... model id); native_provider=openrouter is the serving gateway.
Usage
python3 .agents/skills/gemma-runner/scripts/run_gemma.py "your prompt here"
Examples
python3 .agents/skills/gemma-runner/scripts/run_gemma.py "Summarize the core module architecture"
python3 .agents/skills/gemma-runner/scripts/run_gemma.py --prompt-file /tmp/review.md --role synthesizer
python3 .agents/skills/gemma-runner/scripts/run_gemma.py "Read-only analysis" --restrict-tools --json
python3 .agents/skills/gemma-runner/scripts/run_gemma.py "Answer from the brief only" --no-tools --json
Behavior
- Delegates to the shared
pi-runnerimplementation with runner identity set togemma(the envelope reportsrunner=gemma,effective_runner=pi). - Pins
--provider openrouter --model google/gemma-4-31b-iton every call, so the Gemma seat is the model that actually answers — there is no mutable provider state that can silently reroute it. - Never falls back to another provider. A missing CLI blocks the seat explicitly (
status: seat_unavailable,return_code -2); missing credentials reportstatus: auth_missingwithauth_ok: false— this is seat fidelity, the same invariant every runner upholds: never substitute another model's answer for the Gemma seat. - Preserves the shared wrapper envelope so councils can compare Gemma output with other runners consistently.
Migration Note
The Cline-backed shim is no longer used by this skill — it now depends solely on pi and OPENROUTER_API_KEY. Minimax remains delegated to cline-runner and is unaffected. If other tooling still shells out to cline directly, that is also unaffected by this change.
Integration
agents/openai.yaml exposes this skill as a native Codex-app subagent seat (Codex UI display metadata and default prompt); do not remove it.
