Documentation Update Skill

This skill automatically regenerates documentation files in the docs/ directory by reading the marketplace catalog and applying Jinja2 templates.

Purpose

Maintain synchronized documentation by:

• Generating agent reference documentation
• Creating skill catalog documentation
• Building plugin directory
• Updating usage guides
• Ensuring consistency across all docs

When to Use

Use this skill when:

• A new plugin is added to the marketplace
• An existing plugin is updated (components added/removed)
• Agent or skill metadata changes
• Documentation needs to be regenerated
• Ensuring docs match marketplace state

Documentation Files

This skill generates four main documentation files:

1. agents.md

Complete reference of all agents across all plugins:

• Organized by plugin
• Lists agent name, description, and model
• Includes links to agent files
• Shows agent capabilities and use cases

2. agent-skills.md

Catalog of all skills with progressive disclosure details:

• Organized by plugin
• Lists skill name and description
• Shows "Use when" triggers
• Includes skill structure information

3. plugins.md

Directory of all plugins in the marketplace:

• Organized by category
• Shows plugin name, description, and version
• Lists components (agents, commands, skills)
• Provides installation and usage information

4. usage.md

Usage guide and command reference:

• Getting started instructions
• Command usage examples
• Workflow patterns
• Integration guides

Template Structure

Templates are stored in assets/ using Jinja2 syntax:

assets/
├── agents.md.j2
├── agent-skills.md.j2
├── plugins.md.j2
└── usage.md.j2

Template Variables

All templates receive the following context:

{
  "marketplace": {
    "name": "marketplace-name",
    "owner": {...},
    "metadata": {...},
    "plugins": [...]
  },
  "plugins_by_category": {
    "category-name": [plugin1, plugin2, ...]
  },
  "all_agents": [
    {
      "plugin": "plugin-name",
      "name": "agent-name",
      "file": "agent-file.md",
      "description": "...",
      "model": "..."
    }
  ],
  "all_skills": [
    {
      "plugin": "plugin-name",
      "name": "skill-name",
      "path": "skill-path",
      "description": "..."
    }
  ],
  "all_commands": [
    {
      "plugin": "plugin-name",
      "name": "command-name",
      "file": "command-file.md",
      "description": "..."
    }
  ],
  "stats": {
    "total_plugins": 10,
    "total_agents": 25,
    "total_commands": 15,
    "total_skills": 30
  }
}

Python Script

The skill includes a Python script doc_generator.py that:

1. Loads marketplace.json

   • Reads the marketplace catalog
   • Validates structure
   • Builds component index

2. Scans Plugin Files

   • Reads agent/command frontmatter
   • Extracts skill metadata
   • Builds comprehensive component list

3. Prepares Template Context

   • Organizes plugins by category
   • Creates component indexes
   • Calculates statistics

4. Renders Templates

   • Applies Jinja2 templates
   • Generates documentation files
   • Writes to docs/ directory

Usage

# Generate all documentation files
python doc_generator.py

# Generate specific file only
python doc_generator.py --file agents

# Dry run (show output without writing)
python doc_generator.py --dry-run

# Specify custom paths
python doc_generator.py \
  --marketplace .claude-plugin/marketplace.json \
  --templates plugins/claude-plugin/skills/documentation-update/assets \
  --output docs

Integration with Commands

The /claude-plugin:create and /claude-plugin:update commands should invoke this skill automatically after marketplace updates:

Workflow

1. Plugin operation completes (add/update/remove)
2. Marketplace.json is updated
3. Invoke documentation-update skill
4. Documentation files regenerated
5. Changes ready to commit

Example Integration

# After creating/updating plugin
print("Updating documentation...")

# Run doc generator
import subprocess
result = subprocess.run(
    ["python", "plugins/claude-plugin/skills/documentation-update/doc_generator.py"],
    capture_output=True,
    text=True
)

if result.returncode == 0:
    print("✓ Documentation updated")
else:
    print(f"❌ Documentation update failed: {result.stderr}")

Template Examples

agents.md.j2

# Agent Reference

This document lists all agents available across plugins in the marketplace.

{% for category, plugins in plugins_by_category.items() %}
## {{ category|title }}

{% for plugin in plugins %}
### {{ plugin.name }}

{{ plugin.description }}

**Agents:**

{% for agent in all_agents %}
{% if agent.plugin == plugin.name %}
- **{{ agent.name }}** (`{{ agent.model }}`)
  - {{ agent.description }}
  - File: `plugins/{{ plugin.name }}/agents/{{ agent.file }}`
{% endif %}
{% endfor %}

{% endfor %}
{% endfor %}

*Last updated: {{ now }}*
*Total agents: {{ stats.total_agents }}*

agent-skills.md.j2

# Agent Skills Reference

This document catalogs all skills with progressive disclosure patterns.

{% for plugin in marketplace.plugins %}
## {{ plugin.name }}

{{ plugin.description }}

**Skills:**

{% for skill in all_skills %}
{% if skill.plugin == plugin.name %}
### {{ skill.name }}

{{ skill.description }}

- **Location:** `plugins/{{ plugin.name }}/skills/{{ skill.path }}/`
- **Structure:** SKILL.md + assets/ + references/

Error Handling

Marketplace Not Found

Error: Marketplace file not found: .claude-plugin/marketplace.json
Suggestion: Ensure marketplace.json exists

Template Not Found

Error: Template file not found: assets/agents.md.j2
Suggestion: Ensure all template files exist in assets/

Invalid Plugin Structure

Warning: Plugin 'plugin-name' missing components
Suggestion: Verify plugin has agents or commands

Frontmatter Parse Error

Warning: Could not parse frontmatter in agents/agent-name.md
Suggestion: Check YAML frontmatter syntax

Best Practices

1. Always Regenerate After Changes

   • Run after every plugin add/update/remove
   • Ensure docs stay synchronized
   • Commit documentation with plugin changes

2. Validate Before Generation

   • Run marketplace validation first
   • Fix any errors or warnings
   • Ensure all files exist

3. Review Generated Output

   • Check generated files for correctness
   • Verify formatting and links
   • Test any code examples

4. Template Maintenance

   • Keep templates simple and readable
   • Use consistent formatting
   • Document template variables

5. Version Control

   • Commit documentation changes
   • Include in pull requests
   • Document significant changes

Template Customization

Adding New Sections

To add a new section to a template:

1. Modify Template

   ## New Section

   {% endfor %}
   

   Copy

2. Update Context (if needed)

   • Add new data to template context in doc_generator.py
   • Process additional metadata

3. Test Output

   • Run generator with dry-run
   • Verify formatting
   • Check for errors
