Skill: Polling and WebSocket Parity

When to Use

Use this skill for any real-time feature that touches transport behavior.

Core Workflow

  1. Implement feature changes in the primary socket path.
  2. Mirror equivalent behavior in polling wrappers/fallback logic.
  3. Confirm command names and payload shapes are transport-neutral.
  4. Validate environment switch, pane update, and callback routing in both modes.
  5. Ensure no mode-specific regressions in reconnect/reload behavior.

Guardrails

  • Do not ship socket-only features.
  • Keep command contracts stable across both modes.
  • Avoid mode-specific payload forks unless explicitly versioned.
