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 ``` > ๐Ÿ“š **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 > ๐Ÿ“š **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` > ๐Ÿ“š **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 > ๐Ÿ“š **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 #

| ๐ŸŸข Always | --- ## ๐Ÿ”Œ 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. --- ## ๐Ÿช† 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. --- ## ๐Ÿ”„ 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. --- ## ๐Ÿงช 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 . ``` > ๐Ÿ“š **Full testing guide:** See [TESTING_GUIDE.md](TESTING_GUIDE.md) for step-by-step commands covering the full implemented runtime surface. --- ## ๐Ÿ” 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` | --- ## ๐Ÿ”Ž 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. --- ## โš ๏ธ Disclaimer - This repository is a **Python reimplementation** inspired by the Claude Code npm architecture. - It does **not** ship the original npm source. - It is **not** affiliated with or endorsed by Anthropic. ---
