What it does

JS Echarts To Streamlit is an agent skill from andfanilo/streamlit-echarts-demo. Transforms JavaScript ECharts options and demos into Python dictionary configurations compatible with streamlit-echarts.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Streamlit, JavaScript and Python. The repository describes itself as: Demo for Streamlit ECharts component.

Example prompts

  • “Use the js-echarts-to-streamlit skill to transform JavaScript ECharts options and demos into Python dictionary configurations compatible with…”
  • “/js-echarts-to-streamlit”

Requirements

  • Python 3

Workflow steps

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

  1. Data Structures & Primitives
  2. Data Preparation & Logic
  3. Handling JavaScript via JsCode (Critical)
  4. Series as Dict vs List
  5. Faithful Conversion
  6. Interactivity & Drilldown Pattern
  7. Limitations

What it can do on your machine

Read from SKILL.md and the folder at commit 988789c. 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 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:

    • echarts.apache.org

    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

JS Echarts To Streamlit loads about 1.6k tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 449 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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 449 words (~1,613 tokens).

“This skill converts standard JavaScript/TypeScript Apache ECharts examples into Python code rendered with streamlit-echarts.”
