What problem does it solve? Learners often don't know their actual proficiency level or how to structure their study time, leading to unfocused practice and slow progress. This Skill conducts a graduated proficiency assessment, places the learner on the CEFR scale across six skills, and produces a structured, evidence-based learning plan. ## Core Features & Use Cases - CEFR Placement Assessment: Conducts graduated-difficulty questioning from A1 to C2 and rates reading, writing, listening, speaking, vocabulary, and grammar separately. - Personalized Learning Plan: Generates goals, hour-based timelines, Nation's Four Strands practice structure, resource recommendations, and milestone checkpoints. - Learner Data Persistence: Saves profile.json and plan.json under Language-Tutor/learner-data so other tutoring agents can continue from the assessment. - Use Case: A user says they want to learn Korean for travel with 45 minutes a day. The Skill assesses them at A2, documents weaker speaking skills, and creates a 6-month plan targeting B1 with milestones and recommended practice activities. ## Quick Start Ask the assistant to assess your current level in your target language and create a personalized CEFR-based learning plan.
