A specialized skill for systematically classifying error patterns and constructing concept deficit maps. Used by error-analyst and diagnostician agents when analyzing learner error data to diagnose root causes and develop customized remediation strategies. Automatically applied in contexts such as 'error patterns', 'wrong answer analysis', 'concept deficits', 'weakness analysis', 'error types'. However, psychological testing and learning disability diagnosis are outside the scope of this skill.
A specialized skill that enhances the error-analyst and diagnostician agents' error analysis capabilities.
Definition: The core concept is not understood or is misunderstood Signal: Repeated errors on questions related to the same concept Prescription: Concept re-learning -> varied examples -> self-explanation
Example: All normalization questions answered incorrectly
-> Functional dependency concept itself is inaccurate
-> Prescription: Re-learn functional dependency + step-by-step normalization practice
Definition: The concept is understood but mistakes occur during application Signal: Errors occur at a specific step in the solution process Prescription: Step-by-step checklist + repeated practice
Example: Understands SQL JOIN concept but gets wrong results with multiple JOINs
-> JOIN order and condition application procedure error
-> Prescription: Step-by-step JOIN worksheet + progressively increasing complexity
Definition: Understands the material but makes errors due to inattention Signal: Same question type is sometimes right, sometimes wrong; increases under time pressure Prescription: Verification habits + time management training
Definition: Falls for intentional error-inducing devices set by the question writer Signal: Repeatedly selects attractive distractors Prescription: Trap pattern learning + "Why is this NOT the answer?" training
Definition: The area has not been studied at all Signal: Guessing-level accuracy (25%) on a specific topic Prescription: New study of the area is required
### Error Analysis Results
#### 1. Error Type Distribution
| Error Type | Count | Ratio | Severity |
|-----------|-------|-------|---------|
| Conceptual gap | 8 | 32% | High |
| Procedural error | 5 | 20% | Medium |
| Careless mistake | 4 | 16% | Low |
| Trap error | 5 | 20% | Medium |
| Knowledge gap | 3 | 12% | High |
#### 2. Concept Deficit Map
[Concept A] <- Prerequisite concept
|
[Concept B] <- Deficit discovered here
|
[Concept C] <- Cannot learn (requires B first)
#### 3. Remediation Priority Order
