## ๐ About
This repository reimplements the [Claude Code](https://docs.anthropic.com/en/docs/claude-code) npm agent architecture **entirely in Python**, designed to run with **local open-source models** via an OpenAI-compatible API server.
Built on the public porting workspace from [instructkr/claw-code](https://github.com/instructkr/claw-code), the active development lives at [HarnessLab/claw-code-agent](https://github.com/HarnessLab/claw-code-agent).
> **Goal:** Not to ship the original npm source, but to reimplement the full agent flow in Python โ prompt assembly, context building, slash commands, tool calling, session persistence, and local model execution.
>
> **Zero external dependencies** โ just Python's standard library.

## ๐ฆ Requirements
| Requirement | Details |
|-------------|---------|
| ๐ Python | `3.10` or higher |
| ๐ Dependencies | **None** โ pure Python standard library |
| ๐ฅ๏ธ Model Server | `vLLM`, `Ollama`, `LiteLLM Proxy`, or `OpenRouter`, with tool calling support |
| ๐ง Model | [`Qwen/Qwen3-Coder-30B-A3B-Instruct`](https://huggingface.co/Qwen/Qwen3-Coder-30B-A3B-Instruct) (recommended) |
---
## ๐ Quick Start
### 1. Start vLLM with Qwen3-Coder
vLLM must be started with automatic tool choice enabled. Use the `qwen3_xml` parser for Qwen3-Coder tool calling:
```bash
python -m vllm.entrypoints.openai.api_server \
--model Qwen/Qwen3-Coder-30B-A3B-Instruct \
--host 127.0.0.1 \
--port 8000 \
--enable-auto-tool-choice \
--tool-call-parser qwen3_xml
```
Verify the server is running:
```bash
curl http://127.0.0.1:8000/v1/models
```
> ๐ **References:** [vLLM Tool Calling Docs](https://docs.vllm.ai/en/v0.13.0/features/tool_calling/) ยท [OpenAI-Compatible Server](https://docs.vllm.ai/en/v0.13.0/serving/openai_compatible_server.html)
### Optional: Use Ollama Instead of vLLM
`claw-code-agent` can also work with Ollama because the runtime targets an OpenAI-compatible API. Use a model that supports tool calling well.
Example:
```bash
ollama serve
ollama pull qwen3
```
Then configure:
```bash
export OPENAI_BASE_URL=http://127.0.0.1:11434/v1
export OPENAI_API_KEY=ollama
export OPENAI_MODEL=qwen3
```
Notes:
- prefer tool-capable models such as `qwen3`
- plain chat-only models are not enough for full agent behavior
- Ollama does not use the `vLLM` parser flags shown above
> ๐ **References:** [Ollama OpenAI Compatibility](https://docs.ollama.com/api/openai-compatibility) ยท [Ollama Tool Calling](https://docs.ollama.com/capabilities/tool-calling)
### Optional: Use LiteLLM Proxy
`claw-code-agent` can also work through LiteLLM Proxy because the runtime targets an OpenAI-compatible chat completions API. The routed model still needs to support tool calling for full agent behavior.
Quick start example:
```bash
pip install 'litellm[proxy]'
litellm --model ollama/qwen3
```
LiteLLM Proxy runs on port `4000` by default. Then configure:
```bash
export OPENAI_BASE_URL=http://127.0.0.1:4000
export OPENAI_API_KEY=anything
export OPENAI_MODEL=ollama/qwen3
```
Notes:
- LiteLLM Proxy gives you an OpenAI-style gateway in front of many providers
- tool use still depends on the underlying routed model and provider behavior
- if you configure a LiteLLM master key, use that instead of `anything`
> ๐ **References:** [LiteLLM Docs](https://docs.litellm.ai/) ยท [LiteLLM Proxy Quick Start](https://docs.litellm.ai/)
### Optional: Use OpenRouter
`claw-code-agent` can also work with [OpenRouter](https://openrouter.ai/), a cloud API gateway that provides access to models from OpenAI, Anthropic, Google, Meta, and others through a single OpenAI-compatible endpoint. No local model server required.
Configure:
```bash
export OPENAI_BASE_URL=https://openrouter.ai/api/v1
export OPENAI_API_KEY=sk-or-v1-your-key-here
export OPENAI_MODEL=openai/gpt-4o-mini
```
Notes:
- sign up at [openrouter.ai](https://openrouter.ai/) and create an API key under [Keys](https://openrouter.ai/keys)
- model names use the `provider/model` format (e.g. `anthropic/claude-sonnet-4`, `openai/gpt-4o`, `google/gemini-2.5-pro`)
- tool calling support varies by model โ check the [model list](https://openrouter.ai/models) for capabilities
- this sends your conversation (including file contents and shell output) to OpenRouter and the upstream provider โ do not use with repos containing secrets or sensitive data
> ๐ **References:** [OpenRouter Docs](https://openrouter.ai/docs) ยท [Supported Models](https://openrouter.ai/models) ยท [API Keys](https://openrouter.ai/keys)
### 2. Configure Environment
```bash
export OPENAI_BASE_URL=http://127.0.0.1:8000/v1
export OPENAI_API_KEY=local-token
export OPENAI_MODEL=Qwen/Qwen3-Coder-30B-A3B-Instruct
```
### Use Another Model With vLLM
If you want to try another model, keep the same `vLLM` server setup and change the `--model` value when you launch `vLLM`.
Example:
```bash
python -m vllm.entrypoints.openai.api_server \
--model your-model-name \
--host 127.0.0.1 \
--port 8000 \
--enable-auto-tool-choice \
--tool-call-parser your_parser
```
Then update:
```bash
export OPENAI_MODEL=your-model-name
```
Notes:
- the documented path in this repository is `vLLM`
- the model must support tool calling well enough for agent use
- some model families require a different `--tool-call-parser`
- slash commands such as `/help`, `/context`, and `/tools` are local and do not require the model server
### 3. Run the Agent
```bash
# Read-only question
python3 -m src.main agent \
"Read src/agent_runtime.py and summarize how the loop works." \
--cwd .
# Write-enabled task
python3 -m src.main agent \
"Create TEST_QWEN_AGENT.md with one line: test ok" \
--cwd . --allow-write
# Shell-enabled task
python3 -m src.main agent \
"Run pwd and ls src, then summarize the result." \
--cwd . --allow-shell
# Interactive chat mode
python3 -m src.main agent-chat --cwd .
# Streaming output
python3 -m src.main agent \
"Explain the current architecture." \
--cwd . --stream
```

## ๐ Plugin System
Claw Code Agent supports a **manifest-based plugin runtime**. Drop a `plugin.json` in a `plugins/` subdirectory:
```json
{
"name": "my-plugin",
"hooks": {
"beforePrompt": "Inject guidance into the system prompt.",
"afterTurn": "Run after each agent turn.",
"onResume": "Reapply state on session resume.",
"beforePersist": "Save state before session is saved.",
"beforeDelegate": "Inject guidance before child agents.",
"afterDelegate": "Process child agent results."
},
"toolAliases": [
{ "name": "my_read", "baseTool": "read_file", "description": "Custom read alias." }
],
"virtualTools": [
{ "name": "my_tool", "description": "A virtual tool.", "responseTemplate": "result: {input}" }
]
}
```
> See [TESTING_GUIDE.md](TESTING_GUIDE.md) **Section 19** for full plugin testing commands.
---
## ๐ช Nested Agent Delegation
The agent can delegate subtasks to child agents with full context carryover:
```bash
python3 -m src.main agent \
"Delegate a subtask to inspect src/agent_runtime.py and return a summary." \
--cwd . --show-transcript
```
Features:
- Sequential and parallel subtask execution
- Dependency-aware topological batching
- Child-session save and resume
- Agent manager lineage tracking
> See [TESTING_GUIDE.md](TESTING_GUIDE.md) **Section 20** for delegation testing commands.
---
## ๐ Session Persistence
Each `agent` run automatically saves a resumable session:
```text
session_id=4f2c8c6f9c0e4d7c9c7b1b2a3d4e5f67
session_path=.port_sessions/agent/4f2c8c6f...
```
Resume a previous session:
```bash
python3 -m src.main agent-resume \
4f2c8c6f9c0e4d7c9c7b1b2a3d4e5f67 \
"Continue the previous task and finish the missing parts."
```
Resume directly into interactive chat:
```bash
python3 -m src.main agent-chat \
--resume-session-id \
--cwd .
```
Inspect saved sessions:
```bash
ls -lt .port_sessions/agent
```
> **Note:** Run `agent-resume` from the same `claw-code/` directory where the session was created. A resumed session continues from the saved transcript, not from scratch.
---
## ๐งช Testing
Run the full test suite:
```bash
python3 -m unittest discover -s tests -v
```
Smoke tests:
```bash
python3 -m src.main agent "/help"
python3 -m src.main agent-context --cwd .
python3 -m src.main agent \
"Read src/agent_session.py and summarize the message flow." \
--cwd .
```
> ๐ **Full testing guide:** See [TESTING_GUIDE.md](TESTING_GUIDE.md) for step-by-step commands covering the full implemented runtime surface.

## ๐ Permission Model
Claw Code Agent uses a **tiered permission system** to keep the agent safe by default:
| Tier | Capability | Flag Required |
|------|-----------|---------------|
| **Read-only** | List, read, glob, grep | None (default) |
| **Write** | + file creation and editing | `--allow-write` |
| **Shell** | + shell command execution | `--allow-shell` |
| **Unsafe** | + destructive shell operations | `--unsafe` |
---
## ๐ Parity Status
The full implementation checklist tracking parity against the npm `src` lives in [PARITY_CHECKLIST.md](PARITY_CHECKLIST.md).
It covers: core runtime, CLI modes, prompt assembly, context/memory, slash commands, tools, permissions, plugins, MCP, REPL/TUI, remote features, editor integrations, and internal subsystems.
