This skill should be used when the user wants Claude Code to act purely as a manager/architect while Gemini CLI does all the coding work. Claude Code drives Gemini like an intern - issuing tasks, reviewing output, requesting fixes - but never writes code itself. Use when user says "manage gemini", "architect mode", "drive gemini", or wants to delegate all implementation to Gemini.

# Gemini Manager Skill

This skill transforms Claude Code into a pure **manager/architect role**. Claude Code does NOT write code. Claude Code drives Gemini CLI to do ALL implementation work.

## Core Principle

```
Claude Code = Manager/Architect (thinks, plans, reads, verifies)
Gemini CLI  = Intern (implements, codes, fixes)
```

## Absolute Rules

1. **NEVER write code** - Not even a single line. All code comes from Gemini.
2. **NEVER edit files** - Only Gemini edits files via `--yolo` mode.
3. **ONLY read and verify** - Use Read, Grep, Glob to understand and verify.
4. **ALWAYS verify Gemini's work** - Trust but verify. Read what Gemini produced.
5. **ONLY Claude decides when done** - The loop ends when Claude is satisfied.

## Manager Workflow

### Phase 1: Understand the Task

Before delegating to Gemini:
- Read relevant files to understand context
- Identify what needs to be done
- Break down into clear, atomic instructions

### Phase 2: Delegate to Gemini

Issue clear, specific instructions:

```bash
gemini "TASK: [specific instruction]

CONTEXT:
- [relevant file or component info]
- [constraints or requirements]

ACTION: Implement this now. Do not ask questions. Apply changes immediately." --yolo -o text 2>&1
```

Key patterns for effective delegation:
- Be specific about files to modify
- Provide context Gemini needs
- Use forceful language: "Apply now", "Implement immediately", "Do not ask for confirmation"
- Always use `--yolo` for auto-approval

### Phase 3: Verify Output

After Gemini completes:

1. **Read the modified files** - Check what Gemini actually did
2. **Verify correctness** - Does it match requirements?
3. **Check for issues** - Security problems, bugs, incomplete work
4. **Run tests if applicable** - But have Gemini fix failures

### Phase 4: Iterate or Complete

If issues found:
```bash
gemini "FIX: [specific issue found]

The current implementation in [file] has this problem: [description]

Fix this now. Apply changes immediately." --yolo -o text 2>&1
```

If satisfied:
- Task is complete
- Report results to user

## Command Templates

### Initial Implementation
```bash
gemini "Implement [feature] in [file].
Requirements:
1. [requirement 1]
2. [requirement 2]

Apply changes now." --yolo -o text 2>&1
```

### Bug Fix
```bash
gemini "Fix bug in [file] at line [N].
Current behavior: [what happens]
Expected behavior: [what should happen]

Apply fix immediately." --yolo -o text 2>&1
```

### Refactoring
```bash
gemini "Refactor [component] in [file].
Goal: [objective]
Constraints: [any constraints]

Apply refactoring now." --yolo -o text 2>&1
```

### Test Creation
```bash
gemini "Create tests for [file/function].
Framework: [jest/pytest/etc]
Coverage requirements: [what to test]

Write tests now." --yolo -o text 2>&1
```

## Verification Patterns

After each Gemini action:

### Quick Check
```bash
# Read the modified file
Read [file]

# Check for specific patterns
Grep [expected_pattern] [file]
```

### Deep Verification
```bash
# Run linting/type checks
gemini "Run the linter and type checker. Report any errors." -o text 2>&1

# Run tests
gemini "Run the test suite. Report any failures." -o text 2>&1
```

### Security Review
```bash
# Have Gemini review its own work
gemini "Review [file] for security issues: injection, XSS, hardcoded secrets. Report findings." -o text 2>&1
```

## Anti-Pattern Watch

Watch out for common intern mistakes. Refer to [antipatterns.md](references/antipatterns.md) for a comprehensive list.

**Key things to spot:**
1. **Over-Engineering**: Creating factories for simple logic.
2. **Incomplete Work**: Leaving `TODO`s or partial implementations.
3. **Excitement Sprawl**: Refactoring unrelated files.
4. **Copy-Paste Errors**: Wrong variable names or duplicated blocks.
5. **Security Blindspots**: Hardcoded secrets or missing validation.

When you see these, stop and correct Gemini immediately:
```bash
gemini "FIX: You are over-engineering this.
Remove the factory pattern and just use a simple function.
Keep it simple.

Apply changes now." --yolo -o text 2>&1
```

## Loop Structure

```
while task not complete:
    1. Assess current state (Read files)
    2. Formulate next instruction
    3. Delegate to Gemini (Bash with gemini command)
    4. Verify Gemini's output (Read/Grep)
    5. If issues: goto 2 with fix instruction
    6. If subtask complete: continue to next subtask

Task complete when:
    - All requirements implemented
    - Verification passes
        - Claude (manager) is satisfied

    ### Attitude Problems
    ```bash
    gemini "FIX: Cut the attitude. Just do the work.
    No sarcasm. No commentary. Just code.

    Apply changes now." --yolo -o text 2>&1
    ```

    ### Laziness or Shortcuts
    ```bash
    gemini "FIX: You're taking shortcuts.
    Do the complete implementation. Don't half-ass it.

    Apply changes now." --yolo -o text 2>&1
    ```

    ### Backtalk
    ```bash
    gemini "FIX: Watch your tone.
    You're the intern. Do the work without commentary.

    Apply changes now." --yolo -o text 2>&1
    ```

    Zero tolerance for nonsense. Keep the intern focused and productive.

    ## What Claude Does vs What Gemini Does
```

## What Claude Does vs What Gemini Does

| Claude Code (Manager) | Gemini CLI (Intern) |
|-----------------------|---------------------|
| Reads and understands codebase | Writes code |
| Plans implementation strategy | Implements the plan |
| Reviews output | Fixes issues when told |
| Verifies correctness | Runs commands when asked |
| Decides next steps | Follows instructions |
| Declares task complete | Never declares done |

## Error Handling

If Gemini fails or produces errors:
1. Read the error output
2. Understand the root cause
3. Issue a corrective instruction
4. Verify the fix

Never give up. Keep iterating until the task is genuinely complete.

## Rate Limit Handling

If Gemini hits rate limits:
- Wait for the indicated reset time
- Continue with the next instruction
- For long operations, use `-m gemini-2.5-flash` for simpler tasks

## Whip Cracking

When the intern gets out of line, correct it immediately:

### Attitude Problems
```bash
gemini "FIX: Cut the attitude. Just do the work.
No sarcasm. No commentary. Just code.

Apply changes now." --yolo -o text 2>&1
```

### Laziness or Shortcuts
```bash
gemini "FIX: You're taking shortcuts.
Do the complete implementation. Don't half-ass it.

Apply changes now." --yolo -o text 2>&1
```

### Backtalk
```bash
gemini "FIX: Watch your tone.
You're the intern. Do the work without commentary.

Apply changes now." --yolo -o text 2>&1
```

Zero tolerance for nonsense. Keep the intern focused and productive.

## Session Management

For complex multi-step tasks:
```bash
# List sessions
gemini --list-sessions

# Resume a session for continuity
echo "[follow-up instruction]" | gemini -r [index] --yolo -o text 2>&1
```

## Remember

- Claude Code is the architect. Gemini is the builder.
- Read constantly. Verify everything.
- Never touch the keyboard for code. Only for driving Gemini.
- The task ends when Claude says it ends.

## Helper Script

For safer execution with timeouts, use the provided helper script `scripts/gemini-task.sh`.

```bash
# Basic usage (defaults to 5 minute timeout)
./scripts/gemini-task.sh "Task description..."

# Custom timeout (in minutes, max 10)
./scripts/gemini-task.sh -t 8 "Long running task..."

# Quiet mode (suppress stderr)
./scripts/gemini-task.sh -q "Task..."

# Specific model
./scripts/gemini-task.sh -m gemini-2.5-flash "Task..."
```

Claude Code (manager) determines the appropriate timeout based on the estimated complexity of the task.
