Market Chart Renderer

Render Chinese market charts from standardized bars data with MA5/10/20/60, MACD indicators, ECharts templates, and export to HTML/PNG.

Security Scan

The code and runtime instructions are internally consistent with a chart-rendering utility that computes indicators, builds ECharts JSON/HTML and optionally uses headless Chrome for PNG — nothing requested appears disproportionate or unrelated to that purpose.

Purpose & Capability

Name/description (render market charts with MA/MACD, ECharts, HTML/PNG export) match the provided code: indicator calculation, payload/option building, HTML generation, and a check for headless Chrome. The SKILL.md states an external data-provider dependency (akshare_router_cn), and the code imports that module as expected.

Instruction Scope

SKILL.md instructs running the included Python scripts and outputs to output/generated/images/*. The code writes files to that output directory and imports a sibling data-provider module (skills/akshare-futures-options-data/akshare_router_cn.py). Importing an external module at runtime means the skill will execute that module's code; this is expected for a dependency but you should verify the akshare_router_cn implementation. No evidence that the skill reads unrelated system files or environment variables beyond manipulating its own output directory.

Install Mechanism

There is no install spec and no downloads. This is effectively an instruction+code skill that relies on environment-provided headless Chrome/Chromium and Python libraries (pandas). No remote install URLs or archive extraction were present.

Credentials

The skill declares no required environment variables, no credentials, and the code does not attempt to read secrets. It does search PATH for common Chrome binaries (google-chrome/chromium/chromium-browser) which is coherent with its stated PNG export capability. The only external dependency that runs is the akshare_router_cn module; that is functionally required for obtaining 'bars' data but should be reviewed separately.

Persistence & Privilege

The skill does not request always:true or any elevated persistent privileges and does not modify other skills' configs. It writes outputs under its own output path as described in SKILL.md, which is appropriate for a renderer.

Assessment

This skill appears coherent for rendering market charts. Before installing or running it: 1) Ensure you trust the referenced data-provider module (skills/akshare-futures-options-data/akshare_router_cn.py) because it will be imported and run at runtime. 2) Make sure pandas and a Chrome/Chromium binary are available if you want PNG output; otherwise it will produce HTML/JSON only. 3) Inspect the generated HTML (the skill likely embeds ECharts and possibly loads JS from CDNs) if you are concerned about network activity when opening the file in headless Chrome. 4) Run the skill in a sandbox or isolated environment if you plan to use untrusted data-provider code. There are no requests for secrets or unusual system access in the provided files.
