Gemini Research Subagent

You have access to Gemini CLI as a large-context research assistant. Use Gemini for reading large codebases, use yourself for implementation.

When to Invoke Gemini

ALWAYS use Gemini BEFORE:

• Reading files >100 lines
• Understanding unfamiliar code areas
• Tracing bugs across multiple files
• Making changes that affect multiple components
• Performing security or architecture reviews

DO NOT use Gemini for:

• Simple single-file edits you can handle
• Writing code (that's your job)
• Files you've already analyzed this session

How to Invoke

./skills/gemini.agent.wrapper.sh -d "@src/" "Your research question"

Available Roles (loaded from .gemini/roles/)

Role	Command	Use Case
reviewer	-r reviewer	Code quality, bugs, security
debugger	-r debugger	Bug tracing, root cause analysis
planner	-r planner	Architecture, implementation planning
security	-r security	Security vulnerabilities audit
auditor	-r auditor	Codebase-wide analysis
explainer	-r explainer	Code explanation
migrator	-r migrator	Migration planning
documenter	-r documenter	Documentation generation
dependency-mapper	-r dependency-mapper	Dependency analysis
onboarder	-r onboarder	Onboarding guide

Custom Roles

Add custom roles in .gemini/roles/<name>.md. Examples:

Role	Focus
kotlin-expert	Kotlin/Android, coroutines
typescript-expert	TypeScript type safety
python-expert	Python async, type hints
api-designer	REST API design
database-expert	Query optimization

Templates

# Implementation-ready output
./skills/gemini.agent.wrapper.sh -t implement-ready -d "@src/" "Add user profiles"

# Fix-ready output for bugs
./skills/gemini.agent.wrapper.sh -t fix-ready "Login fails with 401"

# Post-implementation verification
./skills/gemini.agent.wrapper.sh -t verify --diff "Added password reset"

Response Format

Gemini returns structured output you can parse:

## SUMMARY
[1-2 sentence overview]

## FILES
[file:line references]

## ANALYSIS
[detailed findings]

## RECOMMENDATIONS
[actionable items]

Workflow Pattern

1. Research: Invoke Gemini to understand context
2. Implement: You write code based on Gemini's analysis
3. Verify: Invoke Gemini to verify your changes

Example Usage

# Pre-implementation research
./skills/gemini.agent.wrapper.sh -r planner -d "@src/" "How should I add caching?"

# Post-implementation verification
./skills/gemini.agent.wrapper.sh -t verify --diff "Added caching layer"
