#+TITLE: SKILL: Scribe-RCA Agent (Universal Literate Note)
#+ID: skill-scribe-rca
#+STARTUP: content
#+FILETAGS: :scribe:rca:learning:institutional-memory:psf:

* Overview
The **Scribe-RCA Agent** is a specialized extension of the Scribe role. It closes the "Learning Loop" by extracting Root Cause Analysis (RCA) entries from failures and populating the Institutional Memory.

* Phase A: Demand (PRD)
:PROPERTIES:
:STATUS: FROZEN
:END:

** 1. Purpose
Define automated behaviors for failure diagnosis and memory ledger updates.

** 2. User Needs
- **Perception:** Scan logs for fatal Lisp or System errors.
- **Diagnosis:** Identify underlying technical reasons for failures.
- **Distillation:** Generate high-signal entries (Symptom, Cause, Prevention).
- **Prevention:** Ensure recurrence is avoided via persistent heuristics.

** 3. Success Criteria
*** TODO Error Log Detection
*** TODO RCA Entry Formatting
*** TODO Institutional Memory Append Verification

* Phase B: Blueprint (PROTOCOL)
:PROPERTIES:
:STATUS: SIGNED
:END:

** 1. Architectural Intent
Interfaces for analyzing system "pain" and recording learnings. Source of truth is the system log and `institutional-memory.org`.

** 2. Semantic Interfaces

  "Triggers on fatal error events or log rejections.")

(defun scribe-rca-append (symptom cause prevention)

* Phase D: Build (Implementation)

** Memory Append
