Plexum ProviderPlugin that wraps the local `gemini` CLI binary
(Google Gemini CLI ≥0.37). Same CLI-driven approach as
Plexum-anthropic-provider's contractor mode: each Plexum turn forks
one `gemini -p` subprocess in the agent's workspace dir.
Reference: openclaw/extensions/google/cli-backend.ts.
internal/runner/ (~190 LOC):
- Run() spawns: gemini --skip-trust --output-format json [--model X]
[--resume <sid>] -p <prompt> in agent workspace
- Parses the single JSON blob gemini emits at exit
({"session_id":"...", "response":"...", "stats":{...}})
- session_id persisted at <workspace>/.plexum-gemini-session so the
next turn passes --resume — multi-turn context continuity through
the CLI's own session state
- Emits synthetic message_start + text_delta + message_end events to
match Plexum's streaming agentic-loop contract
- Tolerates the "Ripgrep is not available." stderr preamble (strips
leading non-{ bytes before json.Unmarshal)
cmd/plexum-gemini-provider-plugin/ implements ProviderPluginWithAgent
(receives AgentContext.Workspace from the host).
Models advertised in provider.models:
gemini (no --model flag; CLI default = flash-preview)
gemini-pro → CLI alias "pro" → gemini-3.1-pro-preview
gemini-flash → CLI alias "flash" → gemini-3.1-flash-preview
gemini-flash-lite → CLI alias "flash-lite" → gemini-3.1-flash-lite-preview
Unrecognized model id passes through as --model <id> so operator can
pin a specific gemini-3.x id.
HostConfig (all optional):
binary (default "gemini" — operator should set absolute path
if running under systemd; PATH won't include nvm dirs)
extra_args (appended before -p)
No api_key field — gemini CLI handles auth via ~/.gemini/ state
(OAuth or GEMINI_API_KEY env).
End-to-end verified against local install:
1. CLI embedded turn 1: "Hi, I'm Gemini, your autonomous CLI
agent for software engineering tasks."
2. CLI embedded turn 2: "I said hi as Gemini." (multi-turn ✓ via
--resume)
3. Gateway socket: {"outcome":"text","text":"pong"}
4. Fabric channel e2e: alice → bt2-clean → gem agent → gemini
CLI → outbound REST → seq=19:
"A shrimp's heart is located in its head,
which is quite an unusual biological
arrangement."
Known: when daemon runs under systemd, PATH doesn't include nvm
dirs by default. Operator must set the absolute binary path in
config.json (README notes this).
