What it does
Chart Image is an agent skill from sundial-org/awesome-openclaw-skills. Generate publication-quality chart images from data. Supports line, bar, area, and point charts. Use when visualizing data, creating graphs, plotting time series, or generating chart images for reports/alerts. Designed for Fly.io/VPS deployments - no native compilation, no Puppeteer, no browser required. Pure Node.js with prebuilt binaries.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `CAPABILITY.md`, `scripts/package-lock.json` and `scripts/package.json`).
It sits in Data & Analytics, covering Data visualization and Deployment. It works with Puppeteer and Node.js. The repository describes itself as: Top OpenClaw skills, with the most popular and useful ones.
When your agent uses it
- Visualizing data
- Creating graphs
- Plotting time series
- Generating chart images for reports/alerts
Example prompts
- “/chart-image”
Requirements
- Node.js
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit b80cde2. 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 3 files in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
nodenpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, 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
Chart Image loads about 1.3k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 378 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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 378 words (~1,293 tokens).
“Generate PNG chart images from data using Vega-Lite. Perfect for headless server environments.”
