## Creating a New Plugin

### 1. Create directory structure

```bash
mkdir -p plugins/<plugin-name>/.claude-plugin
mkdir -p plugins/<plugin-name>/skills
mkdir -p plugins/<plugin-name>/agents
mkdir -p plugins/<plugin-name>/commands
```

### 2. Create plugin.json

```json
{
  "name": "<plugin-name>",
  "version": "1.0.0",
  "description": "<Brief description>",
  "author": {
    "name": "hanibalsk",
    "url": "https://github.com/hanibalsk"
  },
  "repository": "https://github.com/hanibalsk/claude-marketplace",
  "license": "MIT",
  "keywords": ["keyword1", "keyword2"]
}
```

### 3. Create CLAUDE.md

Document the plugin with:
- Overview description
- Skills table (if any)
- Agents table (if any)
- Commands table (if any)
- Usage examples

### 4. Add to marketplace.json

Add entry to `.claude-plugin/marketplace.json` plugins array:

```json
{
  "name": "<plugin-name>",
  "version": "1.0.0",
  "description": "<Brief description>",
  "source": "./plugins/<plugin-name>",
  "author": {
    "name": "hanibalsk",
    "url": "https://github.com/hanibalsk"
  },
  "keywords": ["keyword1", "keyword2"]
}
```

## Adding Skills

### Skill file structure

`plugins/<plugin>/skills/<skill-name>/SKILL.md`:

```markdown
---
name: <skill-name>
description: <When to use this skill - triggers on keywords/contexts>
---

# Skill Title

## Content

<Skill content - commands, templates, workflows, etc.>
```

### After adding skills

1. Update plugin's CLAUDE.md with new skill in table
2. Bump version: `./scripts/bump-version.sh <plugin> minor`

## Adding Agents

`plugins/<plugin>/agents/<agent-name>.md`:

```markdown
---
name: <agent-name>
description: <Agent purpose>
model: sonnet  # optional: sonnet, opus, haiku
---

# Agent instructions

<Agent system prompt and behavior>
```

## Adding Commands

`plugins/<plugin>/commands/<command>.md`:

```markdown
---
name: <command>
description: <What the command does>
---

# Command instructions

<What to do when command is invoked>
```

## Version Management

### Bump version script

```bash
# Explicit version
./scripts/bump-version.sh <plugin-name> 1.2.0

# Increment types
./scripts/bump-version.sh <plugin-name> patch  # 1.1.0 → 1.1.1
./scripts/bump-version.sh <plugin-name> minor  # 1.1.0 → 1.2.0
./scripts/bump-version.sh <plugin-name> major  # 1.1.0 → 2.0.0
```

Updates both `plugin.json` and `marketplace.json` automatically.

### When to bump

- **patch**: Bug fixes, typos, minor improvements
- **minor**: New skills, agents, commands added
- **major**: Breaking changes, major restructuring

## Commit Conventions

```bash
# New plugin
git commit -m "feat: add <plugin-name> plugin with <brief description>"

# New skill/agent/command
git commit -m "feat(<plugin>): add <skill/agent/command> for <purpose>"

# Version bump
git commit -m "chore(<plugin>): bump version to X.Y.Z"

# Updates/fixes
git commit -m "fix(<plugin>): <what was fixed>"
```
