What it does

XLSX is an agent skill from jjyaoao/HelloAgents. Comprehensive spreadsheet creation, editing, and analysis with support for formulas, formatting, data analysis, and visualization. When GLM needs to work with spreadsheets (.xlsx, .xlsm, .csv, .tsv, etc) for: (1) Creating new spreadsheets with formulas and formatting, (2) Reading or analyzing data, (3) Modify existing spreadsheets while preserving formulas, (4) Data analysis and visualization in spreadsheets, or (5) Recalculating formulas

Its SKILL.md is about 5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `recalc.py`).

It sits in Documents & Office, covering Excel spreadsheets and Data analysis. It works with Microsoft Excel, openpyxl and LibreOffice. The repository describes itself as: A agent framework based on the tutorial hello-agents.

What it can do on your machine

Read from SKILL.md and the folder at commit c597a7c. 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 script files (Python), which the agent can run.
Shell commands in SKILL.md call:
- 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

XLSX loads about 5k tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 1,784 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~112
When it runs · the whole SKILL.md, loaded when a task matches: ~5k

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

Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,784 words (~4,981 tokens).

“A user may ask you to create, edit, or analyze the contents of an .xlsx file. You have different tools and workflows available for different tasks.”
