## What it does

The skill reads an `improvement-plan-{name}.md` document, categorizes proposed updates by file, and sorts them by priority. High-priority items apply first, covering critical descriptions, structure, or security issues. When overlapping edits conflict, high-priority changes take precedence, or the skill preserves the first change and flags conflicts for manual review.

Before altering files, the tool executes `backup-skill.sh` to copy the original skill into `~/.claude/skills/backup/`. After applying changes via editing tools, `verify-update.sh` confirms YAML syntax and file integrity before producing `update-report-{skill-name}-{timestamp}.md`. The skill cannot run without an existing improvement plan file.

# Skill Improver

Execute improvement plans generated by `skill-quality-reviewer` to automatically update and fix issues in Claude Skills.

## Core Workflow

```
Read improvement-plan-{name}.md
    ↓
Parse improvement items (High/Medium/Low priority)
    ↓
Group changes by file
    ↓
Detect and resolve conflicts
    ↓
Backup original files
    ↓
Execute updates (Edit or Write tools)
    ↓
Verify results
    ↓
Generate update-report
```

## When to Use

**Trigger phrases:**
- "Apply improvements from improvement-plan-git-workflow.md"
- "Update my skill based on the quality report"
- "Execute the improvement plan for api-helper"
- "Fix the issues identified in quality review"

**Use this skill when:**
- Applying improvements from an improvement plan
- Updating a skill based on quality review feedback
- Executing recommended fixes from `skill-quality-reviewer`
- Implementing structured improvements to skill documentation

## Step-by-Step Guide

### Step 1: Load the Improvement Plan

Read the `improvement-plan-{skill-name}.md` file generated by `skill-quality-reviewer`.

```bash
# Plan is typically in current directory
ls improvement-plan-*.md

# Or specify full path
read /path/to/improvement-plan-my-skill.md
```

**Validate the plan:**
- File exists and is readable
- Contains priority sections (High/Medium/Low)
- Has structured improvement items
- Includes file paths and suggested changes

See `references/plan-format.md` for detailed plan structure.

### Step 2: Parse and Group Changes

Extract all improvement suggestions and organize by target file.

**Extract from each item:**
- File path (e.g., `SKILL.md:line:line` or `references/file.md`)
- Dimension (Description Quality, Content Organization, etc.)
- Impact (+X points)
- Current content
- Suggested content
- Reason for change

**Build update queue:**
```
by_file = {
  "SKILL.md": [change1, change2, ...],
  "references/guide.md": [change3, ...],
  "examples/demo.md": [change4, ...],
}
```

### Step 3: Detect and Resolve Conflicts

Check for conflicts when multiple changes affect the same content.

**Resolution strategy:**
1. High priority takes precedence over medium/low
2. If same priority, preserve first change
3. Flag conflicts for manual review
4. Document resolution in update report

See `references/merge-strategies.md` for detailed merge logic.

### Step 4: Sort by Priority

Order changes by priority within each file.

**Priority order:**
1. High Priority (execute first)
2. Medium Priority (execute second)
3. Low Priority (execute last)

### Step 5: Backup and Execute
