* Overview
The CLI Gateway is the simplest interface to Passepartout — raw stdin/stdout over TCP. It connects to the daemon's framed protocol and translates between terminal input/output and the plist-based communication format. No TUI, no ncurses, no dependencies beyond a TCP socket. Every other gateway (TUI, Emacs, Telegram) builds on this same protocol.

** Contract

1. (channel-cli-input text): wraps text in a ~:user-input~ envelope
   with ~:source :CLI~ and injects into the pipeline via
   ~stimulus-inject~.

* Implementation

** Package Context
#+begin_src lisp
(in-package :passepartout)
#+end_src

** CLI Command Handling
;; REPL-VERIFIED: 2026-05-03T13:00:00
#+begin_src lisp
(defun channel-cli-input (text)
  "Processes raw text from the command line."
  (stimulus-inject (list :type :EVENT 
                         :payload (list :sensor :user-input :text text) 
                         :meta (list :source :CLI))))

** Skill Registration
#+begin_src lisp
(defskill :passepartout-channel-cli
  :priority 100
  :trigger (lambda (ctx) (eq (getf (getf ctx :meta) :source) :CLI))
  :deterministic (lambda (action ctx) (declare (ignore ctx)) action))

* Test Suite

#+begin_src lisp
(eval-when (:compile-toplevel :load-toplevel :execute)
  (ql:quickload :fiveam :silent t))

(defpackage :passepartout-channel-cli-tests
  (:use :cl :passepartout)
  (:export #:cli-suite))

(in-package :passepartout-channel-cli-tests)

(fiveam:def-suite cli-suite :description "Verification of the CLI Gateway")
(fiveam:in-suite cli-suite)

(fiveam:test test-channel-cli-input-format
  "Contract 1: channel-cli-input injects a properly formed signal without error."
  (handler-case
      (progn (channel-cli-input "hello") (fiveam:pass))
    (error (c)
      (fiveam:fail "channel-cli-input crashed: ~a" c))))

** Load-Time Sanity Check

Verifies the function exists and can be called at load time without
depending on FiveAM macro resolution in the jailed package.

#+begin_src lisp
(handler-case
    (progn (channel-cli-input "test-load") (log-message "CLI: Load-time test OK"))
  (error (c) (log-message "CLI: Load-time test FAILED: ~a" c)))
