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 | $0.00057 | $0.03261 |
| Opus 5 | $0.00028 | $0.01631 |
| Sonnet 5 | $0.00011 | $0.00652 |
| Haiku 4.5 | $0.00006 | $0.00326 |
Grade A, and why
stuck 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 yesterday.
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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/stuck — diagnose frozen/slow Qwen Code sessions
The user thinks another Qwen Code session on this machine is frozen, stuck, or very slow. Investigate and present a diagnostic report.
What to look for
Scan for other Qwen Code processes (excluding the current one — exclude the PID you see running this prompt). Since Qwen Code is a Node.js CLI (#!/usr/bin/env node), the process name (comm column) is always node (or bun if run with Bun). Identify Qwen Code sessions by looking at the command column for a script path inside a directory whose name starts with qwen-code (matches qwen-code/, qwen-code-dev/, worktree clones, etc.) — anchored to the start of the path or after / so unrelated names like analyze-qwen-code/ don't false-match — or a bin invocation ending in /qwen (the global symlink). Avoid loose qwen-code substring matching: it false-positives on plugin brokers that merely pass a qwen-code path as --cwd.
Signs of a stuck session:
- High CPU (>=90%) sustained — likely an infinite loop. Sample twice, 1-2s apart, to confirm it's not a transient spike.
- Process state
D/U(uninterruptible sleep) — often an I/O hang. Linux usesD, macOS/BSD usesU. Thestatecolumn inpsoutput; first character matters (ignore modifiers like+,s,<). - Process state
T(stopped) — user probably hit Ctrl+Z by accident. - Process state
Z(zombie) — parent isn't reaping. - Very high RSS (>=4GB) — possible memory leak making the session sluggish.
- State
Swith low CPU — the most common hang signature: a hung HTTPS request to the model API. Not a process-level red flag on its own, but combined with the user reporting "stuck", treat it as a strong signal to run the network check in step 3. - Stuck child process — a hung
git,node, or shell subprocess can freeze the parent. Checkpgrep -P <pid>(thenps -pfor state — see step 3) for each session.
Argument validation
If the user gave an argument, treat it as a PID only if it consists entirely of digits 0-9. Anything else — letters, whitespace, punctuation — fails the check, in which case treat it as a free-text symptom description (guidance for the report only, never substituted into shell commands). The strict digit-only whitelist is safer than enumerating shell metacharacters.
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.

stuck is a skill published in the GitHub repository QwenLM/qwen-code (27,507 stars, last pushed yesterday), licensed Apache-2.0. It adds 57 tokens to every session and 3,261 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
