Use when building modular Angular applications requiring dependency injection with providers, injectors, and services.
Use when handling async operations in Angular applications with observables, operators, and subjects.
Use when building Angular 16+ applications requiring fine-grained reactive state management and zone-less change detection.
Guides end-to-end feature development through 8 phases: discover requirements, explore codebase patterns, clarify ambiguities with the user, design architecture, implement with TDD, run multi-agent code review, validate all quality gates, and write a blog post. Use when asked to add a feature, implement a new capability, build functionality, or develop a feature end-to-end.

This skill provides comprehensive guidance for developing Han plugins.
Han supports several plugin categories:
Every plugin must follow this structure:
my-plugin/
├── .claude-plugin/
│ └── plugin.json # Plugin metadata (required)
├── han-plugin.yml # Hook configuration (optional)
├── skills/ # Skills directory (optional)
│ └── my-skill/
│ └── SKILL.md # Skill definition
├── commands/ # Commands directory (optional)
│ └── my-command.md # Slash command
├── hooks/ # Hook scripts (optional)
│ └── my-hook.sh # Hook implementation
└── README.md # Documentation
The plugin.json file defines metadata:
{
"name": "my-plugin-name",
"version": "1.0.0",
"description": "What the plugin does",
"author": {
"name": "Author Name",
"url": "https://author-website.com"
},
"license": "MIT",
"keywords": ["keyword1", "keyword2"]
}
Required fields:
name - Must match directory nameversion - Semantic versioningDefine validation hooks that run at lifecycle events:
hooks:
my-validation:
event: Stop # When to run
command: bash "hooks/my-hook.sh"

# Optional filters:
if_changed: # Only run if these files changed
- "**/*.ts"
dirs_with: # Only run in dirs containing
- "package.json"

Before publishing, validate your plugin:
cd my-plugin
han plugin validate
This checks:
set -e - Exit on first error"${HAN_FILES}" not $HAN_FILESTest your plugin locally:
# Install from local path
han plugin install /path/to/my-plugin --scope project
# Or add to .claude/settings.json manually
Share your plugin:
