gemini-sub-agent

# gemini-sub-agent Use Google Gemini (via subscription, $0 API cost) as a sub-agent inside OpenClaw workflows. ## Setup Run once on a fresh machine: ```bash bash skills/gemini-sub-agent/scripts/setup.sh ``` Then authenticate (headless VPS flow): 1. On VPS: `gcloud auth application-default login --no-browser` → copy the `--remote-bootstrap` URL 2. On laptop: `gcloud auth application-default login --remote-bootstrap="<URL>"` → copy the `localhost:8085` output 3. Paste `localhost:8085` output back into VPS prompt 4. Complete Gemini CLI OAuth: `GOOGLE_GENAI_USE_GCA=true gemini -p "hello"` → paste auth code Credentials are cached indefinitely and auto-refresh. ## Available Models | Model | Use for | |---|---| | `gemini-3.1-pro-preview` | **Default** — latest flagship, best reasoning | | `gemini-2.5-pro` | Stable coding tasks, multi-file edits | | `gemini-3-flash-preview` | Fast summaries, quick Q&A | | `gemini-3-pro-preview` | Previous gen Pro, reliable fallback | | `gemini-2.5-flash` | Lightweight fallback | ## Usage Patterns ### 1. Simple text task (exec) ```bash ask-gemini "your prompt here" ask-gemini -m gemini-2.5-pro "your prompt" ``` ### 2. Pipe large content (long-context) ```bash cat large_file.txt | ask-gemini "summarize this in 5 bullets" cat report.md | ask-gemini "extract all action items" ``` ### 3. Agentic coding (replaces Swift/Sonnet for 30-200 line tasks) ```bash cd /path/to/project GOOGLE_GENAI_USE_GCA=true gemini -m gemini-2.5-pro -y -p "write a script that..." ``` `-y` = yolo mode (auto-approves all file writes and shell commands). Gemini reads/writes files autonomously. ### 4. Pipe files directly into agentic session ```bash cat existing_script.py | GOOGLE_GENAI_USE_GCA=true gemini -m gemini-2.5-pro -y -p "refactor this to add error handling" ``` ## Routing Rules (when to use Gemini vs others) | Task | Use | |---|---| | Text, analysis, summarization | `ask-gemini` | | Medium coding (30–200 lines) | Gemini agentic (`-y`) instead of Swift/Sonnet | | Large file / long-context | `ask-gemini` (1M token window) | | Web search / research | Research agent (Grok) — Gemini has no web access | | Multi-agent orchestration | OpenClaw native (sessions_spawn) | | Complex architecture / debugging | Codex (Opus) — escalate if Gemini fails twice | ## Escalation If Gemini returns wrong output twice on the same task → escalate to Swift (Sonnet) or Codex (Opus). Log the failure in `failures/hot_antipatterns.md` with the task type. ## Scripts - `scripts/setup.sh` — Full install: gemini-cli + gcloud + ask-gemini wrapper - `scripts/ask-gemini` — The wrapper script itself (copy to `/usr/local/bin/`)
