Spawn the ACP-variant runtimes (claude-code-acp / codex-acp / copilot-acp). claude-code-acp validated; it surfaces real tool failures that native claude-code can't. Run with /test-acp-runtime. Pairs with /launch-grackle.
Spawn and exercise the native `claude-code` runtime against a test server, including the model names that work and the synthetic-tool-result gotcha. Run with /test-claude-runtime. Pairs with /launch-grackle.
Spawn the `codex` runtime against a test server. Use model `gpt-5.5` (requires Codex SDK >= 0.135.0). Run with /test-codex-runtime. Pairs with /launch-grackle.
Spawn and exercise the `copilot` runtime against a test server. CRITICAL: gpt-4o does NOT work — use claude-sonnet-4.5. Run with /test-copilot-runtime. Pairs with /launch-grackle.
