What it does

Visual Skills is an agent skill from npc-live/clawfirm. Use this skill whenever the user provides data (CSV, JSON, table, pasted numbers, or any structured dataset) and expects a visual output — even if they don't say 'chart' or 'visualize'. Triggers include: uploading a CSV/Excel and asking 'what does this look like', 'show me this data', 'display this', 'plot this', or any phrasing implying visual understanding. Also triggers when the user pastes tabular data inline and asks for analysis or presentation. The skill reads the data, identifies its semantic type…

Its SKILL.md is about 7.4k 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 Data & Analytics, covering Forecasting and time series, Data cleaning and Excel spreadsheets. It works with Microsoft Excel.

Example prompts

Requirements

Workflow steps

5 steps, taken from the step headings in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit db435ed. 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 javascript, html and python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- cdnjs.cloudflare.com
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

Visual Skills loads about 7.4k tokens when it runs. Until then it costs about 217 tokens; SKILL.md has 930 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~217
When it runs · the whole SKILL.md, loaded when a task matches: ~7.4k

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 930 words (~7,426 tokens).

“When a user provides data, the naive response is to guess a chart type and write ad-hoc code. This produces inconsistent, low-quality visuals. Every chart looks different. Libraries change. Code breaks.”
