## Introduction

**SkillRL-Search-SFT** is a cold-start checkpoint for the search RL environment. 

- Task: Search
- Stage: SFT

## Key Features

- Experience-based Skill Distillation: Transforms successful trajectories into strategic patterns and failed ones into concise lessons from failure.

- Hierarchical SKILLBANK: Organizes knowledge into General Skills for universal strategic guidance and Task-Specific Skills for category-level heuristics.

- Recursive Skill Evolution: A dynamic mechanism where the skill library co-evolves with the agent's policy during RL by analyzing validation failures.

- Context Efficiency: Achieves 10-20% token compression compared to raw trajectory storage while enhancing reasoning utility.
