What this skill does


# Plugin Creator

## Overview

Plugins are shareable packages that bundle skills, agents, commands, hooks, MCP servers, and LSP servers into installable units for Claude Code. A plugin requires only a `.claude-plugin/plugin.json` manifest at minimum; all other components are optional and auto-discovered from conventional directories at the plugin root.

**When to use:** Sharing functionality across projects or teams, distributing through marketplaces, versioning reusable agent capabilities, bundling MCP servers with skills.

**When NOT to use:** Single-project customizations (use `.claude/` directory instead), quick experiments before packaging, personal workflows that do not need distribution.

## Quick Reference

| Component      | Location                       | Format          | Discovery           |
| -------------- | ------------------------------ | --------------- | ------------------- |
| Manifest       | `.claude-plugin/plugin.json`   | JSON            | Required            |
| Skills         | `skills/*/SKILL.md`            | Markdown + YAML | Auto by context     |
| Commands       | `commands/*.md`                | Markdown + YAML | Auto, namespaced    |
| Agents         | `agents/*.md`                  | Markdown + YAML | Auto, `/agents` UI  |
| Hooks          | `hooks/hooks.json`             | JSON            | Auto on events      |
| MCP servers    | `.mcp.json`                    | JSON            | Auto on enable      |
| LSP servers    | `.lsp.json`                    | JSON            | Auto on enable      |
| Output styles  | Custom path                    | Per config      | Via manifest        |
| Plugin env var | `${CLAUDE_PLUGIN_ROOT}`        | Absolute path   | All configs/scripts |
| Project env    | `${CLAUDE_PROJECT_DIR}`        | Absolute path   | All configs/scripts |
| CLI test flag  | `--plugin-dir ./my-plugin`     | Local dev       | Manual load         |
| CLI validate   | `claude plugin validate .`     | Local dev       | Manual check        |
| Install scope  | `--scope user\|project\|local` | CLI flag        | Per install         |

## Common Mistakes

| Mistake                                     | Correct Pattern                                                         |
| ------------------------------------------- | ----------------------------------------------------------------------- |
| Placing components inside `.claude-plugin/` | Only `plugin.json` goes in `.claude-plugin/`; components at plugin root |
| Using absolute paths in configs             | Use `${CLAUDE_PLUGIN_ROOT}` for all plugin file references              |
| Missing `plugin.json` manifest              | Create `.claude-plugin/plugin.json` with at least a `name` field        |
| Path traversal with `../`                   | Keep all files inside the plugin directory                              |
| Non-executable hook scripts                 | Run `chmod +x` on all scripts referenced by hooks                       |
| Forgetting namespacing                      | Plugin skills are invoked as `/plugin-name:skill-name`                  |
| Inline hooks missing event casing           | Event names are case-sensitive: `PostToolUse`, not `postToolUse`        |
| Expecting custom paths to replace defaults  | Custom component paths supplement default directories, not replace them |

## Delegation

- **Plugin component creation**: Build skills, agents, and commands following their respective standards
- **Pattern discovery**: Use `Explore` agent to find existing plugin patterns in the codebase
- **Code review**: Use `Task` agent for plugin structure validation

> If the `meta-skill-creator` skill is available, delegate skill authoring within plugins to it.
> Otherwise, recommend: `npx skills add oakoss/agent-skills --skill meta-skill-creator`
