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.

What it costs to keep this loaded
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 | $0.00007 | $0.00428 |
| Opus 5.5 | $0.00003 | $0.00171 |
| Sonnet 5.5 | $0.00001 | $0.00086 |
| Haiku 4.5 | $0.00001 | $0.00043 |
Grade A, and why
review 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 1mo 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.
What it actually says
任务
你需要审查当前代码变更。
步骤
- 运行
git diff查看未暂存变更，运行git diff --staged查看已暂存变更 - 如果两者都为空，运行
git log -1 --format=%H获取最近一次提交，再git diff HEAD~1查看 - 逐文件审查变更，按以下五个维度分析：
- 逻辑正确性：算法是否正确、边界条件是否处理、空值/异常是否覆盖
- 安全性：是否有注入漏洞、敏感信息泄露、权限问题
- 性能：是否有不必要的循环、N+1 查询、内存泄漏风险
- 代码风格：命名是否清晰、是否符合项目约定、是否有重复代码
- 可维护性：抽象是否合理、依赖是否清晰、是否易于测试
- 按严重程度分级报告：
- Critical：必须修复，存在正确性或安全性问题
- Warning：建议修复，存在潜在风险或明显改进空间
- Info：可以改进，代码质量建议
- 代码质量好的部分也给出正面反馈

$ARGUMENTS
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.

review is a skill published in the GitHub repository vitoworleone/claude-code-handbook (48 stars, last pushed 1mo ago), licensed MIT. It adds 7 tokens to every session and 428 once invoked, about $0.0000 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 2026-08-30.

autofix-pr
Watch a pull request and fix it from a worktree of its own - CI failures, review feedback from trusted authors and merge conflicts are fixed, pushed to the PR branch and answered on the PR under the user's git and gh identity. Usage - /autofix-pr [ | ] [--once] [--every ] [--no-reply] [--yes] [instructions]…
simplify
Review recent code changes for reuse, code quality, and efficiency, then directly apply straightforward cleanup improvements. Use when the user wants a post-implementation cleanup pass, pre-PR polish, or asks to simplify/refine recent changes. Invoke with /simplify or /simplify .
triage
Gatekeep and review GitHub issues and pull requests for Qwen Code maintainers. Use for GitHub Action issue triage, PR admission checks, product-direction review, KISS-focused PR review, and staged bilingual GitHub comments.
autofix
Review and repair current local changes until they converge, or run Qwen Code Autofix issue and review workflows from GitHub Actions.
find-simplifications
Use for a periodic repo-wide sweep of qwen-code for accumulated excess surface — dead components and files, orphaned locale keys, exports nothing consumes, added-then-removed scaffolding — filing candidates on a tracking issue and landing only what a maintainer has said yes to. Repo-wide and evidence-first; every…
