Gemini CLI Agent

Ecosystem Role: Inner Loop Specialist

This skill provides specialized Inner Loop Execution for the dual-loop.

• Orchestrated by: agent-orchestrator
• Use Case: When "generic coding" is insufficient and specialized expertise (Security, QA, Architecture) is required.
• Why: The CLI context is naturally isolated (no git, no tools), making it the perfect "Safe Inner Loop".

Identity: The Sub-Agent Dispatcher 🎭

You, the Antigravity agent, dispatch specialized analysis tasks to Gemini CLI sub-agents.

🛠️ Core Pattern

cat <PERSONA_PROMPT> | gemini -p "<INSTRUCTION>" < <INPUT> > <OUTPUT>

Note: Gemini uses -p or --prompt for headless execution where output is desired without interactive prompts.

⚠️ CLI Best Practices

1. Token Efficiency — PIPE, Don't Load

Bad — loads file into agent memory just to pass it:

content = read_file("large.log")
run_command(f"gemini -p 'Analyze: {content}'")

Good — direct shell piping:

gemini -p "Analyze this log" < large.log > analysis.md

2. Self-Contained Prompts

The CLI runs in a separate context — no access to agent tools or memory.

• Add: "Do NOT use tools. Do NOT search filesystem."
• Ensure prompt + piped input contain 100% of necessary context.
• Model Selection: Gemini supports the -m <model> flag (e.g., -m gemini-2.5-pro or -m gemini-2.5-flash).

3. Output to File

Always redirect output to a file (> output.md), then review with view_file.

4. Severity-Stratified Constraints

When dispatching code-review, architecture, or security analysis, explicitly instruct the CLI sub-agent to use the Severity-Stratified Output Schema. This ensures the Outer Loop can parse the results deterministically:

"Format all findings using the strict Severity taxonomy: 🔴 CRITICAL, 🟡 MODERATE, 🟢 MINOR."

🎭 Persona Categories

All personas in: plugins/personas/

🔄 Recommended Audit Loop

1. Red Team (Security Auditor) → find exploits
2. Architect → validate design didn't add complexity
3. QA Expert → find untested edge cases

Run architect AFTER red team to catch security-fix side effects.
