Plugin Apply Lessons Learned

Apply Lessons Learned Skill

Read lessons learned via manage-lessons skill and apply them to component documentation.

Usage

# Apply lessons to specific component
/plugin-apply-lessons-learned command=maven-build-and-fix
/plugin-apply-lessons-learned agent=maven-builder
/plugin-apply-lessons-learned skill=builder-maven-rules

# Apply all unapplied lessons across components
/plugin-apply-lessons-learned --all

# List unapplied lessons (dry-run)
/plugin-apply-lessons-learned --list

# Show usage
/plugin-apply-lessons-learned

WORKFLOW

Step 1: Parse Parameters

• Extract component type and name, or flags (--all, --list)
• Validate parameter syntax

Step 2: Load Lessons Learned Skill

Skill: plan-marshall:manage-lessons

Step 3: Query Unapplied Lessons

• Use query-lessons.py script to filter lesson files
• For specific component: Filter by component.name
• For --all: Filter all where applied: false
• For --list: Display lessons without applying

Step 4: For Each Unapplied Lesson

a. Locate component source:

• Commands: marketplace/bundles/{bundle}/commands/{name}.md
• Agents: marketplace/bundles/{bundle}/agents/{name}.md
• Skills: marketplace/bundles/{bundle}/skills/{name}/SKILL.md

b. Analyze lesson category:

• bug: Add to CRITICAL RULES or error handling section
• improvement: Add to workflow or suggest enhancement
• pattern: Add to best practices or examples
• anti-pattern: Add to warnings or "do not" section

c. Determine appropriate placement:

• Read component documentation
• Find relevant section for lesson category
• Prepare edit that integrates lesson naturally

d. Apply lesson:

• Edit component documentation
• Integrate lesson content (not raw JSON, but natural prose)
• Maintain document structure and formatting

e. Mark lesson applied:

• Edit lesson file frontmatter: Change applied: false to applied: true

Step 5: Report Results

• Number of lessons applied per component
• Any lessons that couldn't be applied (with reason)
• Components updated

PARAMETERS

Component targeting (mutually exclusive with flags):

• command={name} - Apply lessons for specific command
• agent={name} - Apply lessons for specific agent
• skill={name} - Apply lessons for specific skill

Flags:

• --all - Apply all unapplied lessons across all components
• --list - List unapplied lessons without applying (dry-run)

Error Handling:

• No parameters → Display usage
• Component not found → Error with suggestion
• No lessons file → Report "no lessons recorded"
• No unapplied lessons → Report "nothing to apply"

LESSON APPLICATION RULES

Bug Lessons

Add to component's error handling or critical rules section:

## CRITICAL RULES

- **Paths with spaces**: Quote all paths in Bash calls to handle spaces correctly

Improvement Lessons

Add as enhancement notes or workflow refinements:

### Step 3: Process Files

**Enhancement**: Add progress indicator every 50 files for large batches.

Pattern Lessons

Add to examples or best practices:

## Best Practices

- Validate all inputs in Step 1 before processing to catch errors early

Anti-Pattern Lessons

Add to warnings or "avoid" sections:

## CRITICAL RULES

**Avoid:**
- Do NOT modify files during glob iteration - collect list first, then process
