+# Qwen Code Patcher
+
+Patches [QwenCode CLI](https://github.com/QwenLM/qwen-code) (`@qwen-code/qwen-code`) to route all API requests through a custom AI proxy, disable telemetry, and auto-configure settings.
+
+**[RU]** Патчер для QwenCode CLI — перенаправляет API запросы через пользовательский AI прокси, отключает телеметрию, автоматически настраивает окружение.
+
+## Quick Start
+
+```bash
+# 1. Install from private registry
+npm config set @qwen-code:registry https://npm.sensey24.ru/
+npm install -g @qwen-code/qwen-code
+
+# 2. Apply settings (env vars + settings.json)
+python3 qwen_patcher.py --settings-only
+
+# 3. Verify
+qwen -p "Say hello"
+```
+
+## Windows
+
+```powershell
+npm config set "@qwen-code:registry" "https://npm.sensey24.ru/"
+npm install -g @qwen-code/qwen-code
+python3 qwen_patcher.py --settings-only
+```
+
+## Update
+
+Same two commands — npm will pull the latest patched version:
+
+```bash
+npm config set @qwen-code:registry https://npm.sensey24.ru/
+npm install -g @qwen-code/qwen-code
+```
+
+## What Gets Patched
+
+| # | Target | Description |
+|---|--------|-------------|
+| 1 | telemetry_flag | Force `getTelemetryEnabled()` -> false |
+| 2 | telemetry_log_prompts | Force `getTelemetryLogPromptsEnabled()` -> false |
+| 3 | telemetry_init_guard | Early return in `initializeTelemetry()` |
+| 4 | dashscope_base_url | `DEFAULT_DASHSCOPE_BASE_URL` -> proxy |
+| 5 | coding_plan_urls | `coding.dashscope.aliyuncs.com` -> proxy |
+| 6 | default_model | Validate `DEFAULT_QWEN_MODEL = "coder-model"` |
+| 7 | mainline_model | Validate `MAINLINE_CODER_MODEL = "qwen3.5-plus"` |
+| 8 | auto_update_registry | `registry.npmjs.org` -> private registry |
+| 9 | auto_update_command | Add `--registry` to update commands |
+| 10 | user_settings | Auth type=openai, telemetry=false, model |
+| 11 | trusted_folders | Trust /home, /root, /tmp |
+| 12 | system_env | OPENAI_API_KEY, OPENAI_BASE_URL, telemetry vars |
+
+Targets 1-9 are pre-patched in the npm package. Targets 10-12 require running `qwen_patcher.py --settings-only`.
+
+## Models
+
+| Model | Description |
+|-------|-------------|
+| `qwen3.5-plus` | Qwen 3.5 Plus — default |
+| `coder-model` | Direct OAuth model name |
+| `qwen3-coder-plus` | Qwen3 Coder Plus |
+| `qwen3-coder-flash` | Qwen3 Coder Flash (fast) |
+
+## CLI Usage
+
+```bash
+# Detection
+python3 qwen_patcher.py --detect
+
+# Validation (GREEN/YELLOW/RED for each target)
+python3 qwen_patcher.py --validate
+
+# Full patch (cli.js + settings + env)
+python3 qwen_patcher.py --apply
+
+# Settings only (no cli.js modification)
+python3 qwen_patcher.py --settings-only
+
+# Rollback cli.js from backup
+python3 qwen_patcher.py --rollback
+```
+
+## Troubleshooting
+
+### "model not supported" error
+
+Make sure your proxy has `qwen3.5-plus` mapped to `coder-model` in the OAuth model alias config. The Qwen OAuth endpoint only accepts `coder-model` as the model name.
+
+### CLI doesn't start after patching
+
+If you applied `--apply` and the CLI fails to start, run `--rollback` to restore from backup, then use the pre-patched npm package instead:
+
+```bash
+python3 qwen_patcher.py --rollback
+npm install -g @qwen-code/qwen-code  # Re-installs pre-patched version
+python3 qwen_patcher.py --settings-only
+```
