#+TITLE: SKILL: Web Research Agent (Universal Literate Note)
#+ID: skill-web-research
#+STARTUP: content
#+FILETAGS: :web:research:internet:psf:

* Overview
The **Web Research Agent** provides the bridge to the internet. It fetches and synthesizes information from the web using pluggable engines like Lynx and Curl, enabling real-time research and fact verification.

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

** 1. Purpose
Define the interfaces for internet information retrieval and synthesis.

** 2. User Needs
- **Connectivity:** Pluggable engines (Lynx, Curl) for fetching URLs.
- **Synthesis:** Neural transformation of raw content into factual summaries.
- **Efficiency:** Default to text-only engines to minimize overhead.
- **Search Integration:** Automatic DuckDuckGo routing for general queries.

** 3. Success Criteria
*** TODO Engine Fetching Verification (Lynx/Curl)
*** TODO URL vs Query Routing Logic
*** TODO Neural Synthesis Formatting Accuracy

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

** 1. Architectural Intent
Interfaces for web I/O and content synthesis. Source of truth is the global internet and local CLI browser engines.

** 2. Semantic Interfaces
