godot-signal-architecture — Claude Code skill for Godot signals

A skill with signal architecture rules for Godot: when to emit, when to call directly, how to build an event bus. Handy for wiring nodes and untangling connections.

What godot-signal-architecture does

The skill enforces a "Signal Up, Call Down" pattern. Children report upward with past-tense signals like died or health_changed, parents command downward through direct calls. Siblings talk via a parent mediator or a scoped AutoLoad bus.

Inside are sample scripts: signal_up_call_down_pattern.gd for hierarchy wiring, global_signal_bus_router.gd for cross-scene events, disconnect_ghost_signals.gd when switching tracked emitters, and one_shot_deferred_connections.gd for one-shot and deferred flags. Debug helpers signal_debugger.gd and signal_spy.gd are included too.

Watch out: lambdas that capture locals are not auto-disconnected by Godot, so you must disconnect them manually in _exit_tree(). Connecting the same Callable twice without CONNECT_REFERENCE_COUNTED throws ERR_INVALID_PARAMETER. For high-frequency data the skill suggests shared arrays or buffers instead of emit().

What it helps with

  • Decouple nodes in a hierarchy without hard references
  • Set up a global AutoLoad event bus
  • Clean up duplicate and ghost connections
  • Sequence async steps with await on signals
  • Trace which emitter fired a signal

Example prompts for the agent

  • Design player-to-UI communication with signals using signal up, call down
  • Build a global event bus on AutoLoad for achievements and saves
  • Find duplicate connects and ghost connections in my code, then suggest fixes

Questions about godot-signal-architecture

How do I install godot-signal-architecture in Claude Code?

What does godot-signal-architecture do?

It sets signal rules for Godot: children emit past-tense events upward, parents call downward, siblings go through a mediator or AutoLoad bus. The skill ships scripts for common cases like one-shot connections, disconnecting old targets, and debugging.

How does CONNECT_REFERENCE_COUNTED behave?

It stacks identical connects into one connection with a reference count, so N connects need N disconnects. It does not auto-clean on free and does not fix capturing-lambda leaks.
