 Skills are **model-invoked** — the model autonomously decides when to use them based on your request and the Skill’s description. This is different from slash commands, which are **user-invoked** (you explicitly type `/command`).
 
-If you want to invoke a Skill explicitly, use the `/skills` slash command:
-
-```bash
-/skills <skill-name>
-```
-
-The `/skills` command is only available when you run with `--experimental-skills`. Use autocomplete to browse available Skills and descriptions.

-# JetBrains IDEs
-
-> JetBrains IDEs provide native support for AI coding assistants through the Agent Control Protocol (ACP). This integration allows you to use Qwen Code directly within your JetBrains IDE with real-time code suggestions.
-
-### Features
-
-- **Native agent experience**: Integrated AI assistant panel within your JetBrains IDE
-- **Agent Control Protocol**: Full support for ACP enabling advanced IDE interactions
-- **Symbol management**: #-mention files to add them to the conversation context
-- **Conversation history**: Access to past conversations within the IDE
-
-### Requirements
-
-- JetBrains IDE with ACP support (IntelliJ IDEA, WebStorm, PyCharm, etc.)
-- Qwen Code CLI installed
-
-### Installation
-
-1. Install Qwen Code CLI:
-
-   ```bash
-   npm install -g @qwen-code/qwen-code
-   ```
-
-2. Open your JetBrains IDE and navigate to AI Chat tool window.
-
-3. Click the 3-dot menu in the upper-right corner and select **Configure ACP Agent** and configure Qwen Code with the following settings:
-
-```json
-{
-  "agent_servers": {
-    "qwen": {
-      "command": "/path/to/qwen",
-      "args": ["--acp"],
-      "env": {}
-    }
-  }
-}
-```
-
-4. The Qwen Code agent should now be available in the AI Assistant panel
-
-![Qwen Code in JetBrains AI Chat](./images/jetbrains-acp.png)
-
-## Troubleshooting
-
-### Agent not appearing
-
-- Run `qwen --version` in terminal to verify installation
-- Ensure your JetBrains IDE version supports ACP
-- Restart your JetBrains IDE
-
-### Qwen Code not responding
-
-- Check your internet connection
-- Verify CLI works by running `qwen` in terminal
-- [File an issue on GitHub](https://github.com/qwenlm/qwen-code/issues) if the problem persists

-**Usage notes**:
-- The command argument is required.
-- You can specify an optional timeout in milliseconds (up to 600000ms / 10 minutes). If not specified, commands will timeout after 120000ms (2 minutes).
-- It is very helpful if you write a clear, concise description of what this command does in 5-10 words.
-
-- Avoid using run_shell_command with the \`find\`, \`grep\`, \`cat\`, \`head\`, \`tail\`, \`sed\`, \`awk\`, or \`echo\` commands, unless explicitly instructed or when these commands are truly necessary for the task. Instead, always prefer using the dedicated tools for these commands:
-  - File search: Use glob (NOT find or ls)
-  - Content search: Use grep_search (NOT grep or rg)
-  - Read files: Use read_file (NOT cat/head/tail)
-  - Edit files: Use edit (NOT sed/awk)
-  - Write files: Use write_file (NOT echo >/cat <<EOF)
-  - Communication: Output text directly (NOT echo/printf)
-- When issuing multiple commands:
-  - If the commands are independent and can run in parallel, make multiple run_shell_command tool calls in a single message. For example, if you need to run "git status" and "git diff", send a single message with two run_shell_command tool calls in parallel.
-  - If the commands depend on each other and must run sequentially, use a single run_shell_command call with '&&' to chain them together (e.g., \`git add . && git commit -m "message" && git push\`). For instance, if one operation must complete before another starts (like mkdir before cp, Write before run_shell_command for git operations, or git add before git commit), run these operations sequentially instead.
-  - Use ';' only when you need to run commands sequentially but don't care if earlier commands fail
-  - DO NOT use newlines to separate commands (newlines are ok in quoted strings)
-- Try to maintain your current working directory throughout the session by using absolute paths and avoiding usage of \`cd\`. You may use \`cd\` if the User explicitly requests it.

+      - Database servers: \`mongod\`, \`mysql\`, \`redis-server\`

+      - Any command expected to run indefinitely until manually stopped

+      **Use foreground execution (is_background: false) for:**
+      - One-time commands: \`ls\`, \`cat\`, \`grep\`
+      - Build commands: \`npm run build\`, \`make\`

-**Usage notes**:
-- The command argument is required.
-- You can specify an optional timeout in milliseconds (up to 600000ms / 10 minutes). If not specified, commands will timeout after 120000ms (2 minutes).
-- It is very helpful if you write a clear, concise description of what this command does in 5-10 words.
-
-- Avoid using run_shell_command with the \`find\`, \`grep\`, \`cat\`, \`head\`, \`tail\`, \`sed\`, \`awk\`, or \`echo\` commands, unless explicitly instructed or when these commands are truly necessary for the task. Instead, always prefer using the dedicated tools for these commands:
-  - File search: Use ${ToolNames.GLOB} (NOT find or ls)
-  - Content search: Use ${ToolNames.GREP} (NOT grep or rg)
-  - Read files: Use ${ToolNames.READ_FILE} (NOT cat/head/tail)
-  - Edit files: Use ${ToolNames.EDIT} (NOT sed/awk)
-  - Write files: Use ${ToolNames.WRITE_FILE} (NOT echo >/cat <<EOF)
-  - Communication: Output text directly (NOT echo/printf)
-- When issuing multiple commands:
-  - If the commands are independent and can run in parallel, make multiple run_shell_command tool calls in a single message. For example, if you need to run "git status" and "git diff", send a single message with two run_shell_command tool calls in parallel.
-  - If the commands depend on each other and must run sequentially, use a single run_shell_command call with '&&' to chain them together (e.g., \`git add . && git commit -m "message" && git push\`). For instance, if one operation must complete before another starts (like mkdir before cp, Write before run_shell_command for git operations, or git add before git commit), run these operations sequentially instead.
-  - Use ';' only when you need to run commands sequentially but don't care if earlier commands fail
-  - DO NOT use newlines to separate commands (newlines are ok in quoted strings)
-- Try to maintain your current working directory throughout the session by using absolute paths and avoiding usage of \`cd\`. You may use \`cd\` if the User explicitly requests it.

+# Standalone Release Spec (Bun Native + npm Fallback)
+
+This document describes the target release design for shipping Qwen Code as native
+binaries built with Bun, while retaining the existing npm JS bundle as a fallback
+distribution. It is written as a migration-ready spec that bridges the current
+release pipeline to the future dual-release system.
+
+## Goal
+
+Provide a CLI that:
+
+- Runs as a standalone binary on Linux/macOS/Windows without requiring Node or Bun.
+- Retains npm installation (global/local) as a JS-only fallback.
+- Supports a curl installer that pulls the correct binary from GitHub Releases.
+- Ships multiple variants (x64/arm64, musl/glibc where needed).
+- Uses one release flow to produce all artifacts with a single tag/version.
+
+## Non-Goals
+
+- Replacing npm as a dev-time dependency manager.
+- Shipping a single universal binary for all platforms.
+- Supporting every architecture or OS outside the defined target matrix.
+- Removing the existing Node/esbuild bundle.
+
+## Current State (Baseline)
+
+The current release pipeline:
+
+- Bundles the CLI into `dist/cli.js` via esbuild.
+- Uses `scripts/prepare-package.js` to create `dist/package.json`,
+  plus `vendor/`, `locales/`, and `*.sb` assets.
+- Publishes `dist/` to npm as the primary distribution.
+- Creates a GitHub Release and attaches only `dist/cli.js`.
+- Uses `release.yml` for nightly/preview schedules and manual stable releases.
+
+This spec extends the above pipeline; it does not replace it until the migration
+phases complete.
+
+## Target Architecture
+
+### 1) Build Outputs
+
+There are two build outputs:
+
+1. Native binaries (Bun compile) for a target matrix.
+2. Node-compatible JS bundle for npm fallback (existing `dist/` output).
+
+Native build output for each target:
+
+- dist/<name>/bin/<cli> (or .exe on Windows)
+- dist/<name>/package.json (minimal package metadata)
+
+Name encodes target:
+
+- <cli>-linux-x64
+- <cli>-linux-x64-musl
+- <cli>-linux-arm64
+- <cli>-linux-arm64-musl
+- <cli>-darwin-arm64
+- <cli>-darwin-x64
+- <cli>-windows-x64
+
+### 2) npm Distribution (JS Fallback)
+
+Keep npm as a pure JS/TS CLI package that runs under Node/Bun. Do not ship or
+auto-install native binaries through npm.
+
+Implications:
+
+- npm install always uses the JS implementation.
+- No optionalDependencies for platform binaries.
+- No postinstall symlink logic.
+- No node shim that searches for a native binary.
+
+### 3) GitHub Release Distribution (Primary)
+
+Native binaries are distributed only via GitHub Releases and the curl installer:
+
+- Archive each platform binary into a tar.gz (Linux) or zip (macOS/Windows).
+- Attach archives to the GitHub Release.
+- Provide a shell installer that detects target and downloads the correct archive.
+
+## Detailed Implementation
+
+### A) Target Matrix
+
+Define a target matrix that includes OS, arch, and libc variants.
+
+Target list (fixed set):
+
+- darwin arm64
+- darwin x64
+- linux arm64 (glibc)
+- linux x64 (glibc)
+- linux arm64 musl
+- linux x64 musl
+- win32 x64
+
+### B) Build Scripts
+
+1. Native build script (new, e.g. `scripts/build-native.ts`)
+   Responsibilities:
+
+- Remove native build output directory (keep npm `dist/` intact).
+- For each target:
+  - Compute a target name.
+  - Compile using `Bun.build({ compile: { target: ... } })`.
+  - Write the binary to `dist/<name>/bin/<cli>`.
+  - Write a minimal `package.json` into `dist/<name>/`.
+
+2. npm fallback build (existing)
+   Responsibilities:
+
+- `npm run bundle` produces `dist/cli.js`.
+- `npm run prepare:package` creates `dist/package.json` and copies assets.
+
+Key details:
+
+- Use Bun.build with compile.target = <bun-target> (e.g. bun-linux-x64).
+- Include any extra worker/runtime files in entrypoints.
+- Use define or execArgv to inject version/channel metadata.
+- Use "windows" in archive naming even though the OS is "win32" internally.
+
+Build-time considerations:
+
+- Preinstall platform-specific native deps for bundling (example: bun install --os="_" --cpu="_" for dependencies with native bindings).
+- Include worker assets in the compile entrypoints and embed their paths via define constants.
+- Use platform-specific bunfs root paths when resolving embedded worker files.
+- Set runtime execArgv flags for user-agent/version and system CA usage.
+
+Target name example:
+<cli>-<os>-<arch>[-musl]
+
+Minimal package.json example:
+{
+"name": "<cli>-linux-x64",
+"version": "<version>",
+"os": ["linux"],
+"cpu": ["x64"]
+}
+
+### C) Publish Script (new, optional)
+
+Responsibilities:
+
+1. Run the native build script.
+2. Smoke test a local binary (`dist/<host>/bin/<cli> --version`).
+3. Create GitHub Release archives.
+4. Optionally build and push Docker image.
+5. Publish npm package (JS-only fallback) as a separate step or pipeline.
+
+Note: npm publishing is now independent of native binary publishing. It should not reference platform binaries.
+
+### D) GitHub Release Installer (install)
+
+A bash installer that:
+
+1. Detects OS and arch.
+2. Handles Rosetta (macOS) and musl detection (Alpine, ldd).
+3. Builds target name and downloads from GitHub Releases.
+4. Extracts to ~/.<cli>/bin.
+5. Adds PATH unless --no-modify-path.
+
+Supports:
+
+- --version <version>
+- --binary <path>
+- --no-modify-path
+
+Installer details to include:
+
+- Require tar for Linux and unzip for macOS/Windows archives.
+- Use "windows" in asset naming, not "win32".
+- Prefer arm64 when macOS is running under Rosetta.
+
+## CI/CD Flow (Dual Pipeline)
+
+Release pipeline (native binaries):
+
+1. Bump version.
+2. Build binaries for the full target matrix.
+3. Smoke test the host binary.
+4. Create GitHub release assets.
+5. Mark release as final (if draft).
+
+Release pipeline (npm fallback):
+
+1. Bump version (same tag).
+2. Publish the JS-only npm package.
+
+Release orchestration details to consider:
+
+- Update all package.json version fields in the repo.
+- Update any extension metadata or download URLs that embed version strings.
+- Tag the release and create a GitHub Release draft that includes the binary assets.
+
+### Workflow Mapping to Current Code
+
+The existing `release.yml` workflow remains the orchestrator:
+
+- Use `scripts/get-release-version.js` for version/tag selection.
+- Keep tests and integration checks as-is.
+- Add a native build matrix job that produces archives and uploads them to
+  the GitHub Release.
+- Keep the npm publish step from `dist/` as the fallback.
+- Ensure the same `RELEASE_TAG` is used for both native and npm outputs.
+
+## Edge Cases and Pitfalls
+
+- musl: Alpine requires musl binaries.
+- Rosetta: macOS under Rosetta should prefer arm64 when available.
+- npm fallback: ensure JS implementation is functional without native helpers.
+- Path precedence: binary install should appear earlier in PATH than npm global bin if you want native to win by default.
+- Archive prerequisites: users need tar/unzip depending on OS.
+
+## Testing Plan
+
+- Build all targets in CI.
+- Run dist/<host>/bin/<cli> --version.
+- npm install locally and verify CLI invocation.
+- Run installer script on each OS or VM.
+- Validate musl builds on Alpine.
+
+## Migration Plan
+
+Phase 1: Add native builds without changing npm
+
+- [ ] Define target matrix with musl variants.
+- [ ] Add native build script for Bun compile per target.
+- [ ] Generate per-target package.json.
+- [ ] Produce per-target archives and upload to GitHub Releases.
+- [ ] Keep existing npm bundle publish unchanged.
+
+Phase 2: Installer and docs
+
+- [ ] Add curl installer for GitHub Releases.
+- [ ] Document recommended install paths (native first).
+- [ ] Add smoke tests for installer output.
+
+Phase 3: Default install guidance and cleanup
+
+- [ ] Update docs to recommend native install where possible.
+- [ ] Decide whether npm stays equal or fallback-only in user docs.
+
+## Implementation Checklist
+
+- [ ] Keep `npm run bundle` + `npm run prepare:package` for JS fallback.
+- [ ] Add `scripts/build-native.ts` for Bun compile targets.
+- [ ] Add archive creation and asset upload in `release.yml`.
+- [ ] Add an installer script with OS/arch/musl detection.
+- [ ] Ensure tag/version parity across native and npm releases.
