What it does
Data Formats is an agent skill from A-EVO-Lab/a-evolve. Reading, writing, and converting common data formats (CSV, Excel, JSON, YAML) with correct handling of encoding, types, and edge cases.
Its SKILL.md is about 640 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 and CSV and tabular files. It works with Microsoft Excel. The repository describes itself as: The official repository of "Position: Agentic Evolution is the Path to Evolving LLMs".
When your agent uses it
- Tasks that involve Excel spreadsheets
- Tasks that involve CSV and tabular files
Example prompts
- “/data-formats”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Compute values in Python and write computed values directly
- Use gnumeric to recalculate: ssconvert --recalc file.xlsx file.xlsx
- Use LibreOffice: libreoffice --headless --calc --convert-to xlsx file.xlsx
What it can do on your machine
Read from SKILL.md and the folder at commit 18ba996. 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:
libreofficepip3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip3, 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
Data Formats loads about 638 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 181 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 181 words (~638 tokens).
“openpyxl writes formula strings but does NOT compute them. Verifiers read VALUES, not formulas.”
