Dual-AI engineering loop orchestrating Claude Code (planning/implementation) and Gemini (validation/review). Use when (1) complex feature development requiring validation, (2) high-quality code with security/performance concerns, (3) large-scale refactoring, (4) user requests gemini-claude loop or dual-AI review. Do NOT use for simple one-off fixes or prototypes.

Gemini-Claude Engineering Loop

Workflow Overview

Plan (Claude) → Validate (Gemini) → Implement (Claude) → Review (Gemini) → Fix → Re-validate → Done
Role Responsibility
Claude Architecture, planning, code implementation (Edit/Write/Read)
Gemini Validation, code review, quality assurance

Environment Notice

Non-TTY environment: See gemini-cli SKILL for CLI fundamentals. Key rule: Always use gemini -p "prompt" (headless mode required)

Phase 0: Pre-flight Check

  1. Create context directory: mkdir -p .gemini-loop
  2. Ask user via AskUserQuestion:
    • Model preference (gemini-3-flash-preview (default), gemini-3-pro-preview (complex only))
    • Role mode preference (Review-Only OR Review+Suggest)

Phase 1: Planning (Claude)

  1. Create detailed implementation plan
  2. Break down into clear steps
  3. Document assumptions and risks
  4. Save to .gemini-loop/plan.md

Phase 2: Plan Validation (Gemini)

Ask user for role mode, then execute with timeout: 600000:

gemini -m gemini-3-flash-preview -p "Review this plan: $(cat .gemini-loop/plan.md) ..."

Full prompts by role mode: See commands.md

Save result: > .gemini-loop/phase2_validation.md

Phase 3: Feedback Loop

If issues found:

  1. Summarize Gemini feedback to user
  2. Ask via AskUserQuestion: "Revise and re-validate, or proceed?"
  3. If revise → Update plan → Repeat Phase 2

Phase 4: Implementation (Claude)

  1. Implement using Edit/Write/Read tools
  2. Execute step-by-step with error handling
  3. Save summary to .gemini-loop/implementation.md

Phase 5: Code Review (Gemini)

Execute with timeout: 600000:

gemini -m gemini-3-flash-preview --include-directories ./src -p "Review: $(cat .gemini-loop/plan.md) $(cat .gemini-loop/implementation.md) ..."

Full prompts by role mode: See commands.md

Save result: > .gemini-loop/phase5_review.md

Claude response by severity:

  • Critical → Fix immediately
  • Architectural → Discuss with user
  • Minor → Document and proceed

Phase 6: Iteration

  1. Apply fixes from .gemini-loop/phase5_review.md
  2. Significant changes → Re-validate with Gemini
  3. Loop until quality standards met

Quick Reference

Always use timeout: 600000 (10 min) for all Gemini commands.
