+
+Implementation of the Claude Code npm source architecture in Python.
+
+This repository builds on the public porting workspace from [instructkr/claw-code](https://github.com/instructkr/claw-code) and extends it into a usable Python local-model agent. The goal is not to ship the npm source itself, but to reimplement the agent flow in Python: prompt assembly, context building, slash commands, tool calling, and local model execution.
+
+## Status
+
+The Python runtime is working, but it is not full feature parity with the npm implementation yet.
+
+Implemented now:
+
+- Python CLI agent loop
+- OpenAI-compatible local model backend
+- Qwen3-Coder support through `vLLM`
+- core tools: file read/write/edit, glob, grep, shell
+- context building and `/context`-style usage reporting
+- local slash commands such as `/help`, `/context`, `/tools`, `/memory`, `/status`
+- unit tests for the Python runtime
+
+Not complete yet:
+
+- full plugin and MCP parity
+- complete slash-command parity
+- full interactive REPL/session persistence parity
+- tokenizer-accurate context accounting
+
+## Repository Layout
+
+```text
+claw-code/
+├── README.md
+├── .gitignore
+├── src/
+└── tests/
+```
+
+`src/` contains the Python implementation.
+
+`tests/` contains the unit tests for the Python runtime.
+
+## Requirements
+
+- Python 3.10+
+- a local OpenAI-compatible model server
+- recommended model: `Qwen/Qwen3-Coder-30B-A3B-Instruct`
+
+## Start `vLLM` With Qwen3-Coder
+
+For Qwen3-Coder tool calling, `vLLM` must be started with automatic tool choice enabled. The official `vLLM` tool-calling docs describe `--enable-auto-tool-choice` and `--tool-call-parser`, and Qwen3-Coder should use the `qwen3_xml` parser:
+
+- https://docs.vllm.ai/en/v0.13.0/features/tool_calling/
+- https://docs.vllm.ai/en/v0.13.0/serving/openai_compatible_server.html
+
+Example:
+
+```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
+```
+
+Check that the server is up:
+
+```bash
+curl http://127.0.0.1:8000/v1/models
+```
+
+## Environment Setup
+
+From the `claw-code/` directory:
+
+```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
+```
+
+## How To Run
+
+Show the agent system prompt:
+
+```bash
+python3 -m src.main agent-prompt --cwd .
+```
+
+Show estimated context usage:
+
+```bash
+python3 -m src.main agent-context --cwd .
+```
+
+Show the raw context snapshot:
+
+```bash
+python3 -m src.main agent-context-raw --cwd .
+```
+
+Run a read-only repo question:
+
+```bash
+python3 -m src.main agent \
+  "Read src/agent_runtime.py and summarize how the loop works." \
+  --cwd .
+```
+
+Run a write-enabled task:
+
+```bash
+python3 -m src.main agent \
+  "Create TEST_QWEN_AGENT.md with one line: test ok" \
+  --cwd . \
+  --allow-write
+```
+
+Run a shell-enabled task:
+
+```bash
+python3 -m src.main agent \
+  "Run pwd and ls src, then summarize the result." \
+  --cwd . \
+  --allow-shell
+```
+
+Show the full transcript:
+
+```bash
+python3 -m src.main agent \
+  "Explain the current tool registry." \
+  --cwd . \
+  --show-transcript
+```
+
+Each real `agent` run now saves a resumable session and prints:
+
+```text
+session_id=...
+session_path=...
+```
+
+Resume a previous session:
+
+```bash
+python3 -m src.main agent-resume \
+  <session-id> \
+  "Continue the previous task and finish the missing implementation."
+```
+
+## Resume A Previous Session
+
+Each real `agent` run saves a resumable session automatically.
+
+After a run finishes, the CLI prints:
+
+```text
+session_id=...
+session_path=...
+```
+
+You can continue the same task later by passing the saved session id:
+
+```bash
+python3 -m src.main agent-resume \
+  <session-id> \
+  "Continue the previous task and finish the missing parts."
+```
+
+Example:
+
+```bash
+python3 -m src.main agent-resume \
+  4f2c8c6f9c0e4d7c9c7b1b2a3d4e5f67 \
+  "Continue building the customer e-commerce project and complete the checkout flow."
+```
+
+Session files are stored under:
+
+```text
+.port_sessions/agent/
+```
+
+You can inspect saved sessions with:
+
+```bash
+ls -lt .port_sessions/agent
+```
+
+Important notes:
+
+- Run `agent-resume` from the same `claw-code/` repository where the session was created.
+- If you use `--show-transcript`, the session id is printed after the run output.
+- A resumed session continues from the saved transcript, not from scratch.
+
+## Slash Command Examples
+
+These are handled locally before the model loop:
+
+```bash
+python3 -m src.main agent "/help"
+python3 -m src.main agent "/context" --cwd .
+python3 -m src.main agent "/context-raw" --cwd .
+python3 -m src.main agent "/tools" --cwd .
+python3 -m src.main agent "/memory" --cwd .
+python3 -m src.main agent "/status" --cwd .
+```
+
+## How To Test
+
+Run the full Python test suite:
+
+```bash
+python3 -m unittest discover -s tests -v
+```
+
+Optional 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 .
+```
+
+## Useful Commands
+
+Workspace summary:
+
+```bash
+python3 -m src.main summary
+```
+
+Workspace manifest:
+
+```bash
+python3 -m src.main manifest
+```
+
+Mirrored command inventory:
+
+```bash
+python3 -m src.main commands --limit 10
+```
+
+Mirrored tool inventory:
+
+```bash
+python3 -m src.main tools --limit 10
+```
+
+## Notes
+
+- The Python agent is still CLI-based, but sessions are now persisted and can be resumed with `agent-resume`.
+- `--allow-write` is required before the agent can modify files.
+- `--allow-shell` is required before the agent can execute shell commands.
+- `--unsafe` additionally allows destructive shell operations.
+
+## Disclaimer
+
+- This repository is a Python implementation effort inspired by the Claude Code npm architecture.
+- It does not ship the original npm source.
+- It is not affiliated with or endorsed by Anthropic.
