Qwen Code is an open-source AI coding agent that runs in a terminal and helps developers work with code through language models. It supports multiple model providers and can also be used through IDEs, desktop software, SDKs, and messaging bots.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.01473 |
| Opus 5.5 | $0.00008 | $0.00589 |
| Sonnet 5 | $0.00004 | $0.00295 |
| Haiku 4.5 | $0.00002 | $0.00147 |
Grade A, and why
browser-use scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Browser Use
Browser Use is bundled with Qwen Code and uses the generic Node REPL MCP tools and the Qwen Chrome extension. Do not install a separate Qwen extension or start a separate Browser Use MCP server.
Setup
Install and enable the Qwen Code Chrome extension in the profile the user wants to use. On macOS and Linux, first use of this SDK automatically registers the shared Native Messaging host in the user's installation directory. A browser task opts into this local setup, which can finish before the extension connects. The SDK checks the actual connection and protocol instead of reading Chrome's extension preferences.
If the extension does not connect, ask the user to open Chrome and check the
extension in the intended profile. There is no store listing yet: build the
extension from packages/chrome-extension in the Qwen Code repository (its
README) and load dist/extension through chrome://extensions (Developer mode
→ Load unpacked). After installation or enabling it, retry the connection.
A usable Host of the same protocol is reused. A Host installed by a newer Qwen
Code is never downgraded: if setup reports one, tell the user to update Qwen
Code and stop. The Host files persist after Qwen exits. The user can inspect or
remove them with node <skill-base>/runtime/scripts/native-host-setup.js status
or uninstall; install explicitly switches the Host to this Qwen Code's copy
from the next time Chrome starts it. A later Browser Use initialization can
register the Host again. If required Host files cannot be read or written,
report the failing action and path so the user can resolve access and retry.
Multiple Qwen sessions can use the same profile, each controlling its own tabs.
A tab held by another session reports TAB_OWNERSHIP_CONFLICT. Use another tab
or wait for that session to release it. The setup below binds the runtime to
the default profile through browserAgent.browsers.get('chrome'). Only when the
user names a specific Chrome profile, call browserAgent.browsers.list() before
that line and pass the returned ID to browserAgent.browsers.get(id) instead.
The runtime stays bound to the first profile it connects to; to switch profiles,
call node_repl_reset and run the setup again.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

browser-use is a skill published in the GitHub repository QwenLM/qwen-code (28,072 stars, last pushed today), licensed Apache-2.0. It adds 21 tokens to every session and 1,473 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-19.
