documentation-update

name	documentation-update
description	Regenerates documentation files (agents.md, agent-skills.md, plugins.md, usage.md) from marketplace data using Jinja templates. Use when plugins are added, updated, or removed to keep documentation in sync.

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 }}/`

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

   • 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

   • 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

   {% endfor %}
   

2. Update Context (if needed)

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

3. Test Output
