feat(cli): cap inline shell output with configurable line limit (#3508)
* feat(cli): cap inline shell output with configurable line limit

Long-running shell commands (npm install, find /, build logs) currently
fill the viewport with the full visible PTY buffer (up to availableHeight,
~24 lines on a typical terminal). The output dominates the screen and
pushes prior context off the top.

This caps inline ANSI shell output to a small window (default 5 lines,
matching Claude Code's ShellProgressMessage). The hidden line count is
already surfaced via the existing `+N lines` indicator in
`ShellStatsBar`, so users still know how much was elided.

The cap applies only when nothing in the existing escape-hatch set is
true:
  - `forceShowResult` (errors, !-prefix user-initiated commands,
    tools awaiting confirmation, agents pending confirmation)
  - `isThisShellFocused` (ctrl+f focus on a running embedded PTY shell)
  - `ui.shellOutputMaxLines = 0` (user opt-out)

Also adds a new `ui.shellOutputMaxLines` setting (default 5) so users
can adjust or disable the cap. The SettingsDialog renders it
automatically via the existing `type: 'number'` schema path.

Notes on scope:
  - Only the `'ansi'` display branch is capped. `'string'`, `'diff'`,
    `'todo'`, `'plan'`, `'task'` renderers are untouched.
  - `AnsiOutputDisplay` is only produced by shell tools (`shell.ts`,
    `shellCommandProcessor.ts`), so other tool outputs are unaffected.
  - The `+N lines` count is bounded by the headless xterm buffer height
    (~30 rows) — a pre-existing limitation of the buffer-based stats,
    not introduced here.

Tests:
  - 4 new ToolMessage tests cover cap default, forceShowResult bypass,
    settings disable (cap=0), and custom cap value.
  - The existing `MockAnsiOutputText` / `MockShellStatsBar` mocks were
    extended to print `availableTerminalHeight` / `displayHeight` so
    the cap behavior is asserted at the prop level.

* fix(cli): apply shell output cap to completed string display too

Initial PR caught only the streaming ANSI branch. AI shell tools emit
the final completed result through `shell.ts:returnDisplayMessage =
result.output`, which is a plain string. That string went through
`StringResultRenderer` with the unmodified `availableHeight`, so the
cap was effectively bypassed for the steady-state display the user
actually sees most of the time.

Verified manually in tmux: a `seq 1 30` invocation by the AI now
collapses to "first 26 lines hidden ... 27 28 29 30" instead of
listing all 30 rows. `!`-prefix `seq 1 30` still expands fully via
the existing `isUserInitiated → forceShowResult` bypass.

Changes:
  - Detect shell tool by name (matches existing `SHELL_COMMAND_NAME` /
    `SHELL_NAME` checks already used in this file)
  - Rename `ansiAvailableHeight` → `shellCapHeight` since it now
    governs the string branch as well
  - Pass `shellCapHeight` to `StringResultRenderer`; the value
    falls back to `availableHeight` for non-shell tools so other
    tools' string output is unaffected
  - Two new tests: shell completed string is capped; non-shell
    string is not
  - Two existing tests updated to use `name="Shell"` so they actually
    exercise the cap path (would previously have passed by accident
    since the original code didn't check tool name)

Also picks up the auto-regenerated VSCode IDE companion settings
schema entry for `ui.shellOutputMaxLines`.

* fix(cli): symmetrize ANSI/string row counts and clamp shell cap input

Addresses two non-blocking review observations on #3508.

Off-by-one between paths:
  MaxSizedBox reserves one row for its overflow banner when content
  exceeds maxHeight (visibleContentHeight = max - 1). The ANSI path
  pre-slices to N in AnsiOutputText so MaxSizedBox sees exactly N
  rows and renders all N — plus the separate ShellStatsBar line.
  The string path passes the raw cap and lets MaxSizedBox handle
  overflow, so it shows N-1 content rows + the banner.

  Result with cap=5: ANSI showed 5+stats, string showed 4+banner.
  Pass shellCapHeight + 1 to StringResultRenderer when capping so
  both paths render N visible content rows. Verified in tmux: the
  completed Shell tool box now reports `... first 25 lines hidden ...`
  followed by lines 26-30 (was 26 + lines 27-30).

Setting validation:
  Schema accepts any number; the dialog only rejects NaN. Negatives
  silently disabled the cap (only 0 is documented as off) and
  fractional values produced fractional slice counts. Added
  Math.max(0, Math.floor(value || 0)) at the use site so:
   - negatives → 0 → cap disabled (matches the documented opt-out)
   - fractions → floor → whole-row cap
   - non-numeric (raw settings.json edits) → 0 → cap disabled
  Schema-level minimum/integer constraints aren't supported by the
  current settings infrastructure (no other number setting uses
  them either), so the guard lives at the use site.

Tests:
  - Updated string-cap test to assert lines 26-30 visible (catches
    the +1 fix; was lines 27-30 before)
  - New parameterized test covers -1, 1.5, and a non-numeric value

Why Qwen Code?

Qwen Code is an open-source AI agent for the terminal, optimized for Qwen series models. It helps you understand large codebases, automate tedious work, and ship faster.

  • Multi-protocol, flexible providers: use OpenAI / Anthropic / Gemini-compatible APIs, Alibaba Cloud Coding Plan, OpenRouter, Fireworks AI, or bring your own API key.
  • Open-source, co-evolving: both the framework and the Qwen3-Coder model are open-source—and they ship and evolve together.
  • Agentic workflow, feature-rich: rich built-in tools (Skills, SubAgents) for a full agentic workflow and a Claude Code-like experience.
  • Terminal-first, IDE-friendly: built for developers who live in the command line, with optional integration for VS Code, Zed, and JetBrains IDEs.

Installation

Linux / macOS

bash -c "$(curl -fsSL https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen.sh)"

Windows (Run as Administrator)

Works in both Command Prompt and PowerShell:

powershell -Command "Invoke-WebRequest 'https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen.bat' -OutFile (Join-Path $env:TEMP 'install-qwen.bat'); & (Join-Path $env:TEMP 'install-qwen.bat')"

Note

: It's recommended to restart your terminal after installation to ensure environment variables take effect.

Manual Installation

Prerequisites

Make sure you have Node.js 20 or later installed. Download it from nodejs.org.

NPM

npm install -g @qwen-code/qwen-code@latest

Homebrew (macOS, Linux)

brew install qwen-code

Quick Start

# Start Qwen Code (interactive)
qwen

# Then, in the session:
/help
/auth

On first use, you'll be prompted to sign in. You can run /auth anytime to switch authentication methods.

Example prompts:

🦞 Use Qwen Code for Coding Tasks in Claw

Copy the prompt below and paste it into your agent:

Use Qwen Code as a coding agent. First, fetch and read this skill reference:
https://raw.githubusercontent.com/QwenLM/qwen-code/refs/heads/main/.qwen/skills/qwen-code-claw/SKILL.md
Then follow the instructions inside to install, authenticate, and use Qwen Code via acpx for all coding tasks.

Authentication

Qwen Code supports the following authentication methods:

  • API Key (recommended): use an API key from Alibaba Cloud Model Studio (Beijing / intl) or any supported provider (OpenAI, Anthropic, Google GenAI, and other compatible endpoints).
  • Coding Plan: subscribe to the Alibaba Cloud Coding Plan (Beijing / intl) for a fixed monthly fee with higher quotas.

⚠️ Qwen OAuth was discontinued on April 15, 2026. If you were previously using Qwen OAuth, please switch to one of the methods above. Run qwen and then /auth to reconfigure.

Use an API key to connect to Alibaba Cloud Model Studio or any supported provider. Supports multiple protocols:

  • OpenAI-compatible: Alibaba Cloud ModelStudio, ModelScope, OpenAI, OpenRouter, and other OpenAI-compatible providers
  • Anthropic: Claude models
  • Google GenAI: Gemini models

The recommended way to configure models and providers is by editing ~/.qwen/settings.json (create it if it doesn't exist). This file lets you define all available models, API keys, and default settings in one place.

Quick Setup in 3 Steps

Step 1: Create or edit ~/.qwen/settings.json

Here is a complete example:

{
  "modelProviders": {
    "openai": [
      {
        "id": "qwen3.6-plus",
        "name": "qwen3.6-plus",
        "baseUrl": "https://dashscope.aliyuncs.com/compatible-mode/v1",
        "description": "Qwen3-Coder via Dashscope",
        "envKey": "DASHSCOPE_API_KEY"
      }
    ]
  },
  "env": {
    "DASHSCOPE_API_KEY": "sk-xxxxxxxxxxxxx"
  },
  "security": {
    "auth": {
      "selectedType": "openai"
    }
  },
  "model": {
    "name": "qwen3.6-plus"
  }
}

Step 2: Understand each field

Field What it does
modelProviders Declares which models are available and how to connect to them. Keys like openai, anthropic, gemini represent the API protocol.
modelProviders[].id The model ID sent to the API (e.g. qwen3.6-plus, gpt-4o).
modelProviders[].envKey The name of the environment variable that holds your API key.
modelProviders[].baseUrl The API endpoint URL (required for non-default endpoints).
env A fallback place to store API keys (lowest priority; prefer .env files or export for sensitive keys).
security.auth.selectedType The protocol to use on startup (openai, anthropic, gemini, vertex-ai).
model.name The default model to use when Qwen Code starts.

Step 3: Start Qwen Code — your configuration takes effect automatically:

qwen

Use the /model command at any time to switch between all configured models.

Tip: You can also set API keys via export in your shell or .env files, which take higher priority than settings.jsonenv. See the authentication guide for full details.

Security note: Never commit API keys to version control. The ~/.qwen/settings.json file is in your home directory and should stay private.

Local Model Setup (Ollama / vLLM)

You can also run models locally — no API key or cloud account needed. This is not an authentication method; instead, configure your local model endpoint in ~/.qwen/settings.json using the modelProviders field.

Ollama setup
  1. Install Ollama from ollama.com
  2. Pull a model: ollama pull qwen3:32b
  3. Configure ~/.qwen/settings.json:
{
  "modelProviders": {
    "openai": [
      {
        "id": "qwen3:32b",
        "name": "Qwen3 32B (Ollama)",
        "baseUrl": "http://localhost:11434/v1",
        "description": "Qwen3 32B running locally via Ollama"
      }
    ]
  },
  "security": {
    "auth": {
      "selectedType": "openai"
    }
  },
  "model": {
    "name": "qwen3:32b"
  }
}
vLLM setup
  1. Install vLLM: pip install vllm
  2. Start the server: vllm serve Qwen/Qwen3-32B
  3. Configure ~/.qwen/settings.json:
{
  "modelProviders": {
    "openai": [
      {
        "id": "Qwen/Qwen3-32B",
        "name": "Qwen3 32B (vLLM)",
        "baseUrl": "http://localhost:8000/v1",
        "description": "Qwen3 32B running locally via vLLM"
      }
    ]
  },
  "security": {
    "auth": {
      "selectedType": "openai"
    }
  },
  "model": {
    "name": "Qwen/Qwen3-32B"
  }
}

Usage

As an open-source terminal agent, you can use Qwen Code in four primary ways:

  1. Interactive mode (terminal UI)
  2. Headless mode (scripts, CI)
  3. IDE integration (VS Code, Zed)
  4. TypeScript SDK

Interactive mode

cd your-project/
qwen

Run qwen in your project folder to launch the interactive terminal UI. Use @ to reference local files (for example @src/main.ts).

Headless mode

cd your-project/
qwen -p "your question"

Use -p to run Qwen Code without the interactive UI—ideal for scripts, automation, and CI/CD. Learn more: Headless mode.

IDE integration

Use Qwen Code inside your editor (VS Code, Zed, and JetBrains IDEs):

TypeScript SDK

Build on top of Qwen Code with the TypeScript SDK:

Configuration

Qwen Code can be configured via settings.json, environment variables, and CLI flags.

File Scope Description
~/.qwen/settings.json User (global) Applies to all your Qwen Code sessions. Recommended for modelProviders and env.
.qwen/settings.json Project Applies only when running Qwen Code in this project. Overrides user settings.

The most commonly used top-level fields in settings.json:

Field Description
modelProviders Define available models per protocol (openai, anthropic, gemini, vertex-ai).
env Fallback environment variables (e.g. API keys). Lower priority than shell export and .env files.
security.auth.selectedType The protocol to use on startup (e.g. openai).
model.name The default model to use when Qwen Code starts.

See the Authentication section above for complete settings.json examples, and the settings reference for all available options.
