## Executive Summary

| Metric | Current | Target |
| --- | --- | --- |
| **Score** | $SCORE/140 ($PERCENT%) | $TARGET_SCORE/140 ($TARGET_PERCENT%) |
| **Grade** | $GRADE | $TARGET_GRADE |
| **Priority** | [PRIORITY] | - |
| **Effort** | [EFFORT] | - |

**Focus Areas**: [Dimension 1], [Dimension 2], [Dimension 3]

**Verdict**: [Assessment of current state]

## Critical Issues to Address

| Issue | Dimension | Severity | Impact |
| --- | --- | --- | --- |
| [Issue 1] | [D#]([score]/[max]) | [Critical/High/Medium/Low] | [Impact] |
| [Issue 2] | [D#]([score]/[max]) | [Critical/High/Medium/Low] | [Impact] |
| [Issue 3] | [D#]([score]/[max]) | [Critical/High/Medium/Low] | [Impact] |

## Detailed Remediation Steps

### Phase 1: [Dimension] - Priority: [Priority]

**Target**: Increase from [current]/[max] to [target]/[max] (+[delta] points)

#### Step 1.1: [Step title]

**[File to modify]**: \`skills/$SKILL_NAME/SKILL.md\`
