After the Probabilistic engine proposes and the Deterministic engine verifies, Act executes the approved action. -The key insight of the Act stage is that *execution is the point of no return*. Once a command is sent to the shell or a file is written, side effects have occurred. Therefore, Act implements a "last-mile" safety check - even after skills have verified the action, there's a final validation before dispatch. - -** Why Separate Actuators? - -The actuator pattern decouples /what to do/ from /how to do it/: - -- The reasoning engine generates action plists like `(:TYPE :REQUEST :TARGET :SHELL :PAYLOAD ...)` -- The actuator interprets the target and executes appropriately -- Adding a new actuator (Telegram, Matrix, etc.) doesn't require changing the reasoning code - -This follows the Open/Closed principle: open for extension, closed for modification. - -** The Feedback Loop - -Act is unique in the pipeline because it can generate new signals. When a tool executes and returns data, that data becomes a new signal that feeds back into Perceive → Reason → Act. - -Example feedback chain: -1. User asks "What files changed today?" -2.
