What it does
Numeric Format Normalization is an agent skill from MichaelYang-lyx/AIDABench. 对 Excel 数据进行数值格式标准化与清洗，支持大规模数据的 Parquet 转换流程，并完成关键指标的合计核对与结果文件导出。
Its SKILL.md is about 510 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 Documents & Office, covering Excel spreadsheets, Database schema design and DataFrames. It works with Microsoft Excel. The repository describes itself as: Code for paper AIDABench: AI Data Analytics Benchmark.
When your agent uses it
- Tasks that involve Excel spreadsheets
- Tasks that involve Database schema design
- Tasks that involve DataFrames
Example prompts
- “/numeric-format-normalization”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 6dd4206. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
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
Numeric Format Normalization loads about 505 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 25 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 25 words (~505 tokens).
