What it does
Regression Test is an agent skill from open-guji/luatex-cn. 运行视觉回归测试验证代码更改是否正确，支持 basic/pastissue/complete 套件及基线更新
Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA. The repository describes itself as: 基于LuaTeX的中文排版宏包，支持古籍版式精确复刻，以及符合W3C《中文排版需求》的现代中文排版. The licence is Apache-2.0.
When your agent uses it
- Testing & QA work in your project
Example prompts
- “/regression-test”
Requirements
- Python 3
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 8c48bdc. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Regression Test loads about 350 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 42 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

回归测试技能
运行回归测试来验证代码更改是否正确。
测试套件
| 套件 | 说明 | 何时运行 |
|---|---|---|
basic (默认) | 核心功能测试 | 每次修改后 |
past_issue | 历史 issue 回归测试 | 偶尔验证 |
complete | 完整书籍测试 | 发版前 |
命令
# 默认：只运行 basic 套件
python3 test/regression_test.py check
# 运行 past_issue 套件
python3 test/regression_test.py check --past-issues
# 运行 complete 套件
python3 test/regression_test.py check --complete
# 运行所有套件
python3 test/regression_test.py check --all
# 检查特定文件（在当前套件中搜索）
python3 test/regression_test.py check banxin
# 保存新基准（仅当预期更改时使用）
python3 test/regression_test.py save banxin使用流程
1. 修改代码后，先检查相关文件
python3 test/regression_test.py check banxin2. 提交前，运行 basic 全部测试
python3 test/regression_test.py check3. 发版前，运行所有套件
python3 test/regression_test.py check --all4. 仅当预期更改时，保存新基准
python3 test/regression_test.py save banxin目录结构
