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"

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
- Research: Invoke Gemini to understand context
- Implement: You write code based on Gemini's analysis
- 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"
