Skill Agent

Author: lfenghx
Version: 0.0.3
Type: Tool (Plugin)

Introduction

Skill Agent is a general-purpose tool plugin based on “Skill Progressive Disclosure”. It treats the local directory as a toolbox, so the model can read the skill manual on demand, then read files / run scripts only when necessary, and finally deliver text or files.

Use Cases

• You want to integrate Skills and constrain/strengthen the model using “manual (SKILL.md) + file structure + scripts”
• You want progress messages and to return generated files as tool outputs
• You want to package capabilities as reusable skill folders (Reference, Scripts, etc.) instead of hard-coding everything in prompts

Features

• Progressive disclosure: skill index → read → read files / run commands as needed
• File delivery: all files in the temp session directory are returned when the agent finishes
• Free execution: the agent can execute commands such as reading/writing files and running scripts
• Controllable memory: configurable memory turns and max step depth

Tool Parameters

This plugin provides two tools:

• “Skill Manager”: manages the local skills directory (list/add/delete skills)
  
  
• “agent_skill”: a general agent that can execute skills that have been stored
  
  

How to Use (in Dify)

Step 1: Install this plugin directly from the Marketplace
Step 2: For self-hosted deployments, set in Dify’s to your Dify address, otherwise Dify cannot fetch uploaded files
Step 3: Build your workflow as shown below

Step 4: Manage skills

Step 5: Chat with Skill Agent

FAQ

1. Installation issues
   If installation fails with network access available, try switching Dify's pip mirror for better dependency download performance. In intranet environments, install via an offline package (contact the author).

2. File transfer issues
   If uploading/downloading files fails (e.g., incorrect URL, download timeout), check whether Dify's has set correctly and whether it matches your Dify address.

3. No output from skill_agent
   This is usually due to the model. Make sure your model and provider plugin support function calling. The author recommends DeepSeek-V3.1 and reports good test results.

4. Skill invocation issues
   The more complete your skill is, the more smoothly the agent can invoke it. Ensure your skill materials and scripts are not missing. For Node.js-script skills, install a Node.js runtime in Dify’s container first.
