Skill Development Framework
Skill Interface Standard
- describe(): Returns skill description (used for AI intent matching)
- validate(params): Validates input parameters
- execute(params, context): Executes skill logic
- cancel(): Cancels ongoing operations
Skill Security Model
| Permission | Description | Requires Authorization |
|---|---|---|
| read | Read data | No |
| write | Write data | No |
| network | Network access | No |
| filesystem | Filesystem access | Yes |
| execute | Execute system commands | Yes |
| admin | Admin operations | Yes |
MCP Tools Ecosystem
- Tool Discovery: Agents automatically discover available MCP tools
- Lazy Loading: Activates relevant tools only when needed
- Permission Management: Security permission control for MCP tools
- Interoperability: Interoperates with MCP ecosystem tools like Claude Code
Role of the Tools Layer in the Ecosystem
- Upward: Provides concrete execution capabilities to the Application Layer
- Downward: Relies on the Core Layer's task scheduling and the Model Layer's AI inference
- Core Value: Extensible capability boundaries, driven by community contributions
Summary
The Tools Layer is the source of OpenClaw's "capabilities," offering a rich collection of tools through built-in skills, community skills, MCP tools, and external APIs. The open skill development framework and MCP standard protocol ensure the continuous expansion of the Tools Layer.
