What problem does it solve?

The X development engineering skill provides practical guidance for building and debugging the Grok-powered Phoenix pipeline, helping teams transition from legacy heuristics to a Rust-based architecture.

Core Features & Use Cases

• Guidance on integrating Grok-native components with the Phoenix transformer for multi-action prediction (Like, Repost, Reply, etc.).
• Architecting candidate sources and two primary retrieval engines: Thunder (In-Network) and Phoenix Retrieval (Out-of-Network).
• Enforcing the pipeline order: Query Hydration -> Sourcing -> Hydration -> Pre-Scoring Filters -> Scoring -> Selection, with a focus on parallelism via Rust's async/await.
• Safety and correctness emphasis: ensure components route through VisibilityLib for compliance and apply strict isolation in scoring to preserve user privacy.

Quick Start

Implement a new Grok-native feature in the Phoenix pipeline that runs hydration and sourcing in parallel for a new ranking signal.
