What it does
Mgsc Table Probe is an agent skill from OpenXiangShan/GEM5. 运行或分析 MGSC 微测试的 SC 子表 A/B 实验，用分支与 MGSCTRACE 统计归因并改进测试。
Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/test-patterns.md` and `scripts/mgsc_table_probe.py`).
The licence is BSD-3-Clause.
Example prompts
- “/mgsc-table-probe”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- 对所有 mgsc_test 二进制执行 probe
- 快速检查单个 case
- 仅重建报告（不重新运行 gem5）
What it can do on your machine
Read from SKILL.md and the folder at commit 0785475. 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
Ships 2 files in scripts/ (Python), which the agent can run.
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
Mgsc Table Probe loads about 628 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 18 tokens; SKILL.md has 160 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); the scripts in this folder are not scanned.

- 运行或分析 MGSC 微测试的 SC 子表 A/B 实验，用分支与 MGSCTRACE 统计归因并改进测试。
MGSC 表探测
概览
运行标准化的 SC 表 A/B 实验，并产出分支级别的归因结果：
summary.csv：case 级别的off与各 profile 的 delta 汇总。branch_delta.csv：分支级别的误预测 delta，以及 SC 修复/伤害与表贡献比例。report.md：便于人工快速阅读的排序报告。
这个 skill 的目标是快速迭代 SC 测试质量，而不是做完整的性能调优。
快速开始
- 对所有
mgsc_test二进制执行 probe：
python3 .agents/skills/mgsc-table-probe/scripts/mgsc_table_probe.py \
--outdir debug/sc_table_probe \
--profiles off,l_only,g_only,i_only,full \
--max-workers 4- 快速检查单个 case：
python3 .agents/skills/mgsc-table-probe/scripts/mgsc_table_probe.py \
--outdir debug/sc_table_probe_smoke \
--tests fp_sc_alias_pair \

--max-workers 1- 仅重建报告（不重新运行 gem5）：
python3 .agents/skills/mgsc-table-probe/scripts/mgsc_table_probe.py \
--outdir debug/sc_table_probe \
--profiles off,l_only,g_only,i_only,full \
--skip-run路径解析
- GEM5 仓库：优先使用
GEM5_HOME，其次从当前目录和脚本位置向上查找SConstruct与configs/example/kmhv3.py。 - MGSC 测试：优先使用
AM_HOME；未设置时才采用本机默认/nfs/home/yanyue/tools/nexus-am。 - 所有路径都可用
--gem5-bin、--config、--cpt-dir和--src-dir显式覆盖。
个人 home 路径只是方便本机使用的 fallback，不是跨机器前提。脚本会在创建运行任务前检查 checkpoint 目录、gem5 binary 和配置文件。
工作流
- 基线 + 单表隔离 profile
- 始终包含
off。 - 在检查
full之前，先加入单表 profile（如g_only、i_only）。
- 快速筛选有价值的测试
- 在
summary.csv中，优先关注满足condMiss_delta < 0且mgsc_net_use > 0的 case。
- 筛选有价值的分支
- 在
branch_delta.csv中，优先关注满足以下条件的行：delta_misp < 0focus_decisive_ratio较高focus_agree_fix_ratio较高
- 决定下一步微测试方向
- 如果
g_only很少带来改善，且focus_decisive_ratio(g)很低，说明 global-history 模式较弱。 - 如果
i_only从未带来帮助，说明循环/迭代相位信号暴露得还不够。 - 可以参考
references/test-patterns.md里的模式来编写下一个测试。
输出
debug/sc_table_probe/summary.csvdebug/sc_table_probe/branch_delta.csvdebug/sc_table_probe/report.mddebug/sc_table_probe/report.json
关键参数
--profiles：从off,l_only,g_only,i_only,full中选择。--tests：逗号分隔的测试名（不带后缀），例如fp_sc_alias_pair,imli_iter。--extra-param：透传额外的 gem5--param。--copy-cpt-to-tmp：避免路径访问问题。--skip-run：仅生成报告，不执行运行。
注意事项
- 除非你明确要评估交互效应，否则在做 SC 子表归因时应保持
microtage关闭。 - 不同 profile 之间必须使用同一组 checkpoint，否则 delta 无效。
- 做 branch PC 映射时，使用 mgsc_test 构建目录下的
*-riscv64-xs.txt反汇编文件。

Can I use Mgsc Table Probe in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add OpenXiangShan/GEM5 --skill mgsc-table-probe -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mgsc-table-probe, .gemini/skills/mgsc-table-probe, .github/skills/mgsc-table-probe and .opencode/skills/mgsc-table-probe in your project.
What does Mgsc Table Probe need to run?
Going by SKILL.md and its folder, Mgsc Table Probe needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3.
Does Mgsc Table Probe access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Mgsc Table Probe safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Mgsc Table Probe use?
Mgsc Table Probe is published under the BSD-3-Clause licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Mgsc Table Probe use?
About 628 tokens (SKILL.md is roughly 2.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 523 tokens, read only when the agent opens those files.
What are the alternatives to Mgsc Table Probe?
Skills that share tags, products or a category with Mgsc Table Probe: Table Fit (asgeirtj/system_prompts_leaks, 69k stars), Table Headers (thedaviddias/Front-End-Checklist, 74k stars), Accessible Tables (thedaviddias/Front-End-Checklist, 74k stars) and Data Table Manager (n8n-io/n8n, 207k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
