What Create Plugin does

The Create Plugin skill is designed for developers looking to extend Claude Code by creating new plugins. This skill automates the initial setup process, ensuring that the resulting plugin adheres to the proper directory structure and conventions. By generating the necessary files and configurations, it streamlines the workflow for plugin development, allowing developers to focus on implementing functionality rather than worrying about boilerplate code.

When using the Create Plugin skill, users will be guided through a series of steps to define their plugin's name and description. The skill checks for naming conflicts to prevent overwriting existing plugins. It then creates a structured directory that includes essential components such as plugin.json, skills, commands, and agents, all organized according to the canonical plugin contract. This organization promotes consistency and clarity within the plugin ecosystem.

Additionally, the skill generates key documentation files, including a README.md that outlines installation instructions, features, and compatibility information. It also creates an Architecture Decision Record (ADR) to document the plugin's design choices, ensuring that developers can maintain clarity and rationale behind their implementation decisions. By automating these processes, the Create Plugin skill significantly reduces the setup time for new plugins, making it an invaluable tool for developers working within the Claude Code framework.

When to use it

Use this skill when you need to create a new plugin for Claude Code that includes skills, commands, and agents, and you want to ensure proper structure and configuration.

When not to use it

This skill is not suitable for modifying existing plugins or for users who need to create plugins without adhering to the Claude Code conventions.

What you can build with it

Creating a New Plugin

Use this skill to quickly scaffold a new plugin that adds unique functionality to Claude Code.

Ensuring Compliance with Standards

Leverage the skill to maintain compliance with Claude Code's plugin structure and conventions, reducing the risk of errors.

Documenting Plugin Decisions

Utilize the generated ADR to keep track of architectural decisions and ensure clarity in your plugin's design.

How to install Create Plugin

View source

1. Install with the skills CLI

npx skills add ruvnet/ruflo/create-plugin --agent claude-code

2. Or install it manually

Download the skill folder and drop it into ~/.claude/skills/ for all projects, or .claude/skills/ to scope it to one repo. Restart Claude Code so it picks up the new skill.

Anthropic's agentic coding CLI, and the reference implementation of Agent Skills. Drop a skill folder into ~/.claude/skills and Claude Code loads it automatically whenever a task matches the skill's description. Claude Code docs

Create Plugin

Scaffold a new Claude Code plugin from scratch.

When to use

When you want to create a new plugin that extends Claude Code with skills, commands, and agents. This generates the correct directory structure and wires up MCP tools.

Steps

  1. Get plugin name and description from the user
  2. Check for conflicts — call mcp__plugin_ruflo-core_ruflo__transfer_plugin-search to ensure the name isn't taken
  3. Create directory structure (follows the canonical plugin contract from sibling plugins' ADR-0001s):
    plugins/<name>/
    ├── .claude-plugin/
    │   └── plugin.json
    ├── skills/
    │   └── <skill-name>/
    │       └── SKILL.md
    ├── commands/
    │   └── <command-name>.md
    ├── agents/
    │   └── <agent-name>.md
    ├── docs/
    │   └── adrs/
    │       └── 0001-<name>-contract.md     # Plugin-level ADR (Proposed)
    ├── scripts/
    │   └── smoke.sh                         # Structural contract (≥8 checks)
    └── README.md                            # Compatibility + Namespace coordination + Verification + ADR sections
    
  4. Generate plugin.json with name, description, version, author (do NOT include skills, commands, or agents arrays — Claude Code auto-discovers these from directory structure)
  5. Generate SKILL.md files with proper frontmatter:
    ---
    name: skill-name
    description: What this skill does
    allowed-tools: mcp__plugin_ruflo-core_ruflo__tool1 mcp__plugin_ruflo-core_ruflo__tool2 Bash
    ---
    
  6. Generate command files with name and description frontmatter
  7. Generate agent files with name, description, and model: sonnet
  8. Generate README.md with install instructions, features, commands, skills, AND the canonical plugin-contract sections:
    • Compatibility — pin to @claude-flow/cli v3.6 major+minor
    • Namespace coordination — claim a kebab-case <plugin-stem>-<intent> namespace; defer to ruflo-agentdb ADR-0001 §"Namespace convention"
    • Verificationbash plugins/<name>/scripts/smoke.sh
    • Architecture Decisions — link to ADR-0001
  9. Generate ADR-0001 (Proposed) at docs/adrs/0001-<name>-contract.md documenting: pinning, namespace coordination, MCP-tool surface count if applicable, smoke contract scope. Status: Proposed.
  10. Generate scripts/smoke.sh — at minimum 8 structural checks: version + keywords; skills/agents/commands present with valid frontmatter; v3.6 pin in README; namespace coordination block in README; ADR exists with status Proposed; no wildcard tools in skills.
  11. Update marketplace.json if adding to the ruflo marketplace.

MCP-tool drift to avoid (per sibling-ADR lessons learned)

Several plugins shipped with subtle MCP bugs the loop has been finding. Don't replicate them:

  • embeddings_embed does not exist. Real tool is embeddings_generate. Don't reference embeddings_embed in any allowed-tools line.
  • agentdb_hierarchical-* does NOT route by namespace. It routes by tier (working|episodic|semantic). Pass tier, not namespace. For namespaced reads/writes, use memory_* instead.
  • agentdb_pattern-* does NOT route by namespace. It routes through ReasoningBank. Don't pass a namespace arg — fallback writes to the reserved pattern namespace via memory-store-fallback.
  • pattern (singular) and patterns (plural) are different namespaces. ReasoningBank fallback writes to pattern; hooks_pretrain writes to patterns. Don't conflate them.

Plugin.json schema

Required fields:

  • name — plugin identifier (kebab-case)
  • description — what the plugin does
  • version — semver

Recommended fields:

  • author{ "name": "...", "url": "..." }
  • homepage, license, keywords

Optional fields:

  • graph_adapter — ADR-130 graph intelligence contract (commented out by default in generated output):
    // "graph_adapter": {
    //   "edgeRelations": ["my-relation-type"],
    //   "nodeTypes": ["entity"],
    //   "autoRegister": true
    // }
    
    When autoRegister: true, the plugin's edges are automatically included in graph_edges writes by the core graph layer. Declare edgeRelations — the relation types this plugin produces.

Do NOT include skills, commands, or agents arrays in plugin.json — these are auto-discovered from the directory structure by Claude Code and will cause validation errors if present.

Available MCP tools to wire

Browse available tools: mcp__plugin_ruflo-core_ruflo__transfer_plugin-info

Common tool categories:

  • memory_* — storage, search, retrieval
  • agentdb_* — 15 controller-bridge tools (do NOT pass namespace arg — they route by tier or ReasoningBank); call agentdb_controllers at runtime for the canonical list
  • neural_* — neural training and prediction
  • hooks_* — lifecycle hooks and intelligence
  • browser_* — browser automation
  • workflow_* — workflow management
  • aidefence_* — safety scanning
  • embeddings_* — 10 vector-embedding tools (use embeddings_generate, NOT embeddings_embed which does not exist)
