Use this skill when

• Designing support for OpenCode, Claude Code, Codex, Gemini, or others
• Refactoring backend-specific logic
• Deciding what the common backend interface should expose

Required outcomes

• Isolate backend-specific transport and session details
• Keep prompt envelope and response shape portable
• Avoid leaking provider-specific types into core code
• Make capability differences explicit

Output checklist

• AgentBackend interface
• Capability notes
• Session semantics
• Migration notes
