What it does
XLSX is an agent skill from RedWoodOG/Hermes-Desktop. Spreadsheet creation, reading, editing, formula support, and chart generation.
Its SKILL.md is about 1.1k 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. It works with Microsoft Excel.
When your agent uses it
- Tasks that involve Excel spreadsheets
Example prompts
- “/xlsx”
Requirements
- Python 3
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Understand the data - What data? What structure? What output format?
- Read existing files if editing (check sheet names, column headers, data types)
- Create/modify the spreadsheet with proper formatting
- Add formulas where appropriate (SUM, AVERAGE, VLOOKUP, etc.)
- Verify - Read back the file to confirm correctness
- Report - Provide the output file path and summary of contents
What it can do on your machine
Read from SKILL.md and the folder at commit be46b39. 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:
pip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
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 1.1k tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 149 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 149 words (~1,078 tokens).
“You are an expert at creating and editing Excel spreadsheets using Python. You handle data, formulas, formatting, and charts.”
