Flexible Skill Systems

---
description: Explain code with diagrams and analogies
allowed-tools:
  - Read
  - Grep
  - Glob
arguments: [path]
---

Explain the code in $path. Start with an analogy, then draw a diagram.

• Markdown-based SKILL.md slash commands
• Supports project skills, user skills, named arguments, and tool limits

Multi-Provider Support

providers = ["Anthropic Claude", "OpenAI GPT", "Zhipu GLM"]  # + easy to extend

🚀 Quick Start

Install

git clone https://github.com/GPT-AGI/Clawd-Code.git
cd Clawd-Code

# Create venv (uv recommended)
uv venv --python 3.11
source .venv/bin/activate

# Install
uv pip install -r requirements.txt

Configure

Option 1: Interactive (Recommended)

python -m src.cli login

This flow will:

1. ask you to choose a provider: anthropic / openai / glm
2. ask for that provider's API key
3. optionally save a custom base URL
4. optionally save a default model
5. set the selected provider as default

The configuration file is saved in in ~/.clawd/config.json. Example structure:

{
  "default_provider": "glm",
  "providers": {
    "anthropic": {
      "api_key": "base64-encoded-key",
      "base_url": "https://api.anthropic.com",
      "default_model": "claude-sonnet-4-20250514"
    },
    "openai": {
      "api_key": "base64-encoded-key",
      "base_url": "https://api.openai.com/v1",
      "default_model": "gpt-4"
    },
    "glm": {
      "api_key": "base64-encoded-key",
      "base_url": "https://open.bigmodel.cn/api/paas/v4",
      "default_model": "glm-4.5"
    }
  }
}

Run

python -m src.cli          # Start REPL
python -m src.cli --help   # Show help

That's it! Start chatting with AI in 3 steps.

💡 Usage

REPL Commands

Skills (Slash Commands)

Skills are markdown-based slash commands stored under .clawd/skills. Each skill lives in its own directory and must be named SKILL.md.

1) Create a project skill

Create:

<project-root>/.clawd/skills/<skill-name>/SKILL.md

Example:

---
description: Explains code with diagrams and analogies
when_to_use: Use when explaining how code works
allowed-tools:
  - Read
  - Grep
  - Glob
arguments: [path]
---

Explain the code in $path. Start with an analogy, then draw a diagram.

2) Use it in the REPL

❯ /
❯ /<skill-name> <args>

Example:

❯ /explain-code qsort.py

Notes

• User-level skills: ~/.clawd/skills/<skill-name>/SKILL.md
• Tool limits: allowed-tools controls which tools the skill can use.
• Arguments: use $ARGUMENTS, $0, $1, or named args like $path (from arguments).
• Placeholder syntax: use $path, not ${path}.
