* System Interface (package.lisp)
The ~package.lisp~ file defines the public API of the ~org-agent~ harness. It serves as the primary membrane between the deterministic core modules and the dynamic world of skills and actuators.

** Architectural Intent: The Package Membrane
By strictly defining the public interface, we ensure that skills remain decoupled from the harness implementation details. This allows for sovereign replacement of any component (e.g., swapping the Memory or the Probabilistic Engine) without breaking existing skills.

** Package Implementation
#+begin_src lisp :tangle ../src/package.lisp
(in-package :org-agent)
#+end_src

** Harness Logging State
The harness maintains a thread-safe circular log buffer to provide context for debugging and neural reasoning.

#+begin_src lisp :tangle ../src/package.lisp
(defvar *system-logs* nil)
(defvar *logs-lock* (bt:make-lock "harness-logs-lock"))
(defvar *max-log-history* 100)
#+end_src

** Skills Registry
#+begin_src lisp :tangle ../src/package.lisp
(defvar *skills-registry* (make-hash-table :test 'equal)
  "Global registry of all loaded skills.")
#+end_src

** Skill Telemetry State
#+begin_src lisp :tangle ../src/package.lisp
(defvar *skill-telemetry* (make-hash-table :test 'equal))
(defvar *telemetry-lock* (bt:make-lock "harness-telemetry-lock"))
#+end_src

** Cognitive Tool Registry
The Tool Registry allows the agent to interact with the physical world. Every tool must define a guard (for security) and a body (for execution).

#+begin_src lisp :tangle ../src/package.lisp
(defvar *cognitive-tools* (make-hash-table :test 'equal))

(defstruct cognitive-tool
  name
  description
  parameters
  guard
  body)

(defmacro def-cognitive-tool (name description parameters &key guard body)
  "Registers a new cognitive tool into the global registry. Parameters must be a list of property lists."
  `(setf (gethash (string-downcase (string ',name)) *cognitive-tools*)
         (make-cognitive-tool :name (string-downcase (string ',name))
                              :description ,description
                              :parameters ',parameters
                              :guard ,guard
                              :body ,body)))

** Harness Logging Implementation
Centralized logging function. It simultaneously writes to standard output and the in-memory circular buffer.

#+begin_src lisp :tangle ../src/package.lisp
(defun harness-log (msg &rest args)
  "Centralized logging for the harness."
  (let ((formatted-msg (apply #'format nil msg args)))
    (bt:with-lock-held (*logs-lock*)
      (push formatted-msg *system-logs*)
      (when (> (length *system-logs*) *max-log-history*)
        (setq *system-logs* (subseq *system-logs* 0 *max-log-history*))))
    (format t "~a~%" formatted-msg)
    (finish-output)))
