package.json Manifest

{
  "name": "@yourname/profclaw-plugin-myplugin",
  "version": "1.0.0",
  "description": "Short description of your plugin",
  "main": "dist/index.js",
  "types": "dist/index.d.ts",
  "exports": {
    ".": {
      "import": "./dist/index.js",
      "types": "./dist/index.d.ts"
    }
  },
  "keywords": ["profclaw-plugin"],
  "profclaw": {
    "pluginId": "myplugin",
    "category": "search",
    "minVersion": "2.0.0",
    "maxVersion": "3.x"
  },
  "peerDependencies": {
    "profclaw": ">=2.0.0"
  }
}
The profclaw.pluginId must be unique on ClawHub. The keywords array must include "profclaw-plugin" for the plugin to appear in search results.

Plugin Manifest Fields

// src/plugins/sdk.ts
export interface PluginManifest {
  name: string;              // npm package name
  version: string;
  description: string;
  main: string;              // Entry point (dist/index.js)
  profclaw: {
    pluginId: string;        // Unique ID
    category: PluginCategory;
    minVersion?: string;     // Min profClaw version
    maxVersion?: string;     // Max profClaw version
  };
}

​
Build Configuration

// tsconfig.json
{
  "compilerOptions": {
    "target": "ES2022",
    "module": "NodeNext",
    "moduleResolution": "NodeNext",
    "outDir": "dist",
    "declaration": true,
    "strict": true,
    "esModuleInterop": true
  },
  "include": ["src/**/*"]
}

​
Build Script

// package.json scripts
{
  "scripts": {
    "build": "tsc",
    "dev": "tsc --watch",
    "test": "vitest",
    "prepublishOnly": "pnpm build"
  }
}

​
Dependencies

Keep dependencies minimal. Avoid bundling:
  • profclaw (declare as peerDependency)
  • zod (available from profClaw peer)
  • Large AI SDKs (prefer HTTP calls)
Bundled dependencies increase install size and can conflict with the host’s versions.

​
Entry Point

src/index.ts must have a default export: 
import { definePlugin } from 'profclaw/plugins/sdk';

const plugin = definePlugin({ ... });

export default plugin;
profClaw imports your plugin with import(packageName) and accesses default.

​
Testing Your Plugin Locally

# In profClaw's profclaw-docs repo or your development setup
pnpm add --workspace ./path/to/my-profclaw-plugin

# Or link globally
cd my-profclaw-plugin && pnpm link --global
cd profclaw && pnpm link --global my-profclaw-plugin
Then register in settings: Settings > Plugins > Install from local path.

​
Scaffolding

Use the built-in scaffolder to bootstrap a new plugin: 
profclaw plugins scaffold --id my-plugin --category search
This generates the package structure with TypeScript config, a sample definePlugin call, and a test file.
