Gemini Context Bridge

🚨 MANDATORY: Invoke gemini-cli-docs First

STOP - Before providing ANY response about GEMINI.md syntax:

  1. INVOKE gemini-cli-docs skill
  2. QUERY for the specific context topic
  3. BASE all responses EXCLUSIVELY on official documentation loaded

Overview

This skill bridges the gap between Claude Code and Gemini CLI by providing workflows to synchronize project context and strategic guidance on agent delegation. It ensures that project conventions defined in CLAUDE.md are understood by Gemini (via GEMINI.md) and helps users leverage the unique strengths of each agent.

When to Use This Skill

Keywords: sync context, share memory, copy instructions, migrate context, bridge agents, gemini.md, claude.md, delegation strategy, agent selection

Use this skill when:

  • Onboarding Gemini: You have a CLAUDE.md and want to initialize a GEMINI.md for Gemini CLI.
  • Syncing Instructions: You want to ensure both agents follow the same coding styles and conventions.
  • Deciding Agent: You are unsure whether to use Claude or Gemini for a specific task (e.g., "Who should run this migration?").
  • Comparing Context: You want to see if there are conflicting instructions between the two agents.

Delegation Strategy (Gemini vs Claude)

When orchestrating tasks, use this guide to choose the right agent:

Delegate to Gemini CLI for

  1. Google Ecosystem Auth: Tasks requiring authenticated access to GCP, Vertex AI, or Firebase.
  2. Long Context / Low Cost: Operations best suited for Gemini Flash (large context) or Pro (very large context).
  3. Interactive Tools: Running interactive CLIs (e.g., top, vim, git rebase) via enableInteractiveShell.
  4. Smart Edits: Using the edit tool with the specific "Smart Edit" strategies of Gemini.
  5. Memory/Todos: Utilizing the built-in programmable save_memory and write_todos tools for state tracking.

Delegate to Claude for

  1. Project Planning: High-level architectural reasoning and convention enforcement (CLAUDE.md).
  2. Complex Refactoring: Codebase-wide changes requiring "Codebase Investigator" analysis.
  3. Initial Setup: Creating the CLAUDE.md that serves as the seed for GEMINI.md.

Workflows

1. Initialize GEMINI.md from CLAUDE.md

Use this to bootstrap Gemini's context using your existing Claude rules.

Manual Steps:

  1. Read CLAUDE.md.
  2. Extract key sections: "Conventions", "Build Commands", "Style Guide".
  3. Create GEMINI.md with these sections formatted for Gemini (Markdown).

2. Check for Context Drift

Periodically check if the two context files have diverged.

Manual Steps:

  1. diff CLAUDE.md GEMINI.md (or visually compare).
  2. Look for updates in one that are missing in the other (e.g., new test command).

File Formats

  • CLAUDE.md: The single source of truth for Claude Code. Contains commands, style guides, and project structure.
  • GEMINI.md: The context file for Gemini CLI. Used to prime the model with project-specific instructions.
  • .gemini/settings.json: Configuration for Gemini (MCP, tools).
  • .claude/config.json (if applicable): Configuration for Claude.

Best Practices for "Partnership"

  • Single Source of Truth: Ideally, treat CLAUDE.md as the master record for project rules.
  • Specialization: Use GEMINI.md for Gemini-specific overrides (e.g., "Always use Flash model for this repo").
  • Shared Memory: While they have separate memory stores, you can manually copy high-value facts from save_memory (Gemini) to save_memory (Claude).

Test Scenarios

Scenario 1: Context Sync

Query: "Sync my CLAUDE.md to GEMINI.md" Expected Behavior:

  • Skill activates on "sync context" or "copy instructions"
  • Provides workflow to extract and transform sections Success Criteria: User receives step-by-step sync workflow

Scenario 2: Agent Selection

Query: "Should I use Claude or Gemini for this large file analysis?" Expected Behavior:

  • Skill activates on "claude or gemini" or "which agent"
  • Provides delegation matrix guidance Success Criteria: User receives recommendation based on task type

Scenario 3: Context Drift Detection

Query: "Check if my CLAUDE.md and GEMINI.md are in sync" Expected Behavior:

  • Skill activates on "compare" or "drift"
  • Suggests diff command and comparison workflow Success Criteria: User receives drift detection method
