What this skill does
# Functional Claude Development
Develop and maintain plugins for the functional-claude Claude Code plugin marketplace.
## Repository Structure
```
functional-claude/
├── .claude-plugin/
│ └── marketplace.json # Marketplace manifest
├── plugins/
│ └── <plugin-name>/ # Individual plugins
│ ├── .claude-plugin/

├── skills/ # Root-level skills (like this one)
└── hooks/
└── hooks.json # Root-level hooks
```
## Version Synchronization
**Critical:** Plugin versions must match across all files. When updating a plugin version:
1. `plugins/<name>/.claude-plugin/plugin.json` - Plugin manifest
2. `.claude-plugin/marketplace.json` - Marketplace listing
3. `plugins/<name>/skills/<skill>/SKILL.md` frontmatter - If skill has version
## Adding a New Plugin
1. Create plugin directory structure:
```bash
mkdir -p plugins/<name>/.claude-plugin
mkdir -p plugins/<name>/skills/<skill-name>/{references,examples}
mkdir -p plugins/<name>/hooks
```
2. Create `plugins/<name>/.claude-plugin/plugin.json`:
```json
{
"name": "<plugin-name>",
"version": "0.1.0",
"description": "Plugin description"
}
```
3. Add to `.claude-plugin/marketplace.json` plugins array:
```json
{
"name": "<plugin-name>",
"source": "./plugins/<plugin-name>",
"description": "Plugin description",
"version": "0.1.0"
}
```
4. Create skill SKILL.md with frontmatter and content
5. Add hooks in `plugins/<name>/hooks/hooks.json` if needed
## Security: Public Repository
This repository is public. Never commit:
- API keys, tokens, or credentials
- `.env` files or environment configurations
- Personal information or private data
- Internal URLs or private endpoints
A PreToolUse hook validates file writes to prevent accidental commits of sensitive data.
## Testing Plugins Locally
```bash
claude --plugin-dir ./plugins/<plugin-name>
```
## Marketplace Installation (for users)
```
/plugin marketplace add nthplusio/functional-claude
/plugin install <plugin-name>@functional-claude
```
