What problem does it solve? Language learners need consistent, structured feedback after every practice answer, and downstream systems need predictable markers to mine error patterns. This Skill enforces a single feedback template across all Fluent practice sessions so corrections, severity levels, and scores stay uniform and parseable. ## Core Features & Use Cases - Standardized Feedback Template: Renders every graded answer with encouragement, per-error corrections, the full correct version, and a score out of 10. - Severity and Category Tagging: Classifies each error as critical, moderate, or minor and labels it with categories like grammar, vocabulary, or prepositions that feed mistakes-db.json. - Spaced Repetition Integration: Converts the answer score into an SM-2 quality value via the fluent-sm2-calculator skill. - Use Case: After a learner submits a Dutch writing exercise in fluent-writing, grade the answer, tag a formal/informal register error as critical, show the corrected sentence, and score it 7/10. ## Quick Start Grade my language practice answer using the standard Fluent feedback template with severity tags and a score out of 10.
