#+TITLE: SKILL: Chat Agent (Universal Literate Note)
#+STARTUP: content
#+FILETAGS: :chat:conversational:ui:psf:
* Overview
The *Chat Agent* provides a dedicated conversational interface within Emacs (`*org-agent-chat*`). It enables fluid dialogue while maintaining strict persona alignment and contextual awareness.
* Phase A: Demand (PRD)
:PROPERTIES:
:STATUS: FROZEN
:END:
** 1. Purpose
Define the interfaces for direct human-to-agent conversational interaction.
** 2. User Needs
- *Direct Interaction:* Specialized handler for `:chat-message` events.
- *Persona Alignment:* Consistency with the Identity Agent's definitions.
- *Contextual Awareness:* Reference to chat history for dialogue continuity.
- *Structural Output:* Responses formatted as valid Org-mode subtrees.
** 3. Success Criteria
*** TODO Chat Event Triggering
*** TODO Persona-Driven Response Generation
*** TODO Emacs Buffer Insertion Verification
* Phase B: Blueprint (PROTOCOL)
:PROPERTIES:
:STATUS: SIGNED
:END:
** 1. Architectural Intent
Interfaces for conversational event handling and UI integration. Source of truth is the dynamic chat buffer and the Identity skill.
** 2. Semantic Interfaces

** Neural Response Generation
The Chat skill acts as the conversational UI. Because the ~org-agent~ kernel evaluates LLM output via ~read-from-string~ (expecting a valid s-expression) and the chat verifier strictly expects an Emacs ~:insert-at-end~ actuation, we must explicitly mandate that the LLM wraps its conversational output in a Common Lisp property list.
#+begin_src lisp :tangle ../projects/org-skill-chat/src/chat-logic.lisp
(defun neuro-skill-chat (context)
"Generates a conversational response, stripping system errors from context."
(let* ((payload (getf context :payload))
(raw-text (getf payload :text))
;; Context Purge: Remove system errors and hallucinations from the history
(clean-text (cl-ppcre:regex-replace-all "(?i)Unknown request|System Error.*|Thinking\\.\\.\\." raw-text ""))
(trimmed-text (if (> (length clean-text) 1000)
(subseq clean-text (- (length clean-text) 1000))
clean-text)))
(ask-neuro trimmed-text :system-prompt "ACTUATOR IDENTITY: You are the pure Lisp actuator for the org-agent kernel.
MANDATE: Output EXACTLY ONE Common Lisp property list starting with (:type :REQUEST).
ZERO CONVERSATION: Do not explain. Do not use markdown.
STRICT RULE: Never output the strings 'Unknown request' or 'System Error'.
REQUIRED FORMATS:
- To reply: (:type :REQUEST :target :emacs :action :insert-at-end :buffer \"*org-agent-chat*\" :text \"* <Response>\")
- To use a tool: (:type :REQUEST :target :tool :action :call :tool \"<name>\" :args (...))")))
