安全使用建议
Safe for normal chart generation. Before installing, be comfortable with npm installing the included dependencies, and when using it, keep chart/spec/output paths controlled by the runtime rather than arbitrary user text. Avoid sending charts containing sensitive data into shared channels unless that is intended.
功能分析
Type: OpenClaw Skill
Name: chart-image
Version: 2.6.35
The 'chart-image' skill is a legitimate utility for generating chart images using Vega-Lite and Sharp. The core logic in 'scripts/chart.mjs' handles data parsing and image rendering without any evidence of malicious intent, such as data exfiltration, backdoors, or unauthorized execution. The documentation in 'CAPABILITY.md' and 'SKILL.md' provides clear, safe instructions for the AI agent, specifically warning against shell injection vulnerabilities by recommending structured argument passing instead of string interpolation. No suspicious dependencies or obfuscated code were detected.
能力评估
Purpose & Capability
The artifacts consistently describe a local Node/Vega-Lite/Sharp chart renderer that accepts data, CSV, or Vega-Lite specs and writes PNG/SVG chart files.
Instruction Scope
The skill invokes a local CLI and supports user-provided data, titles, spec paths, and output paths; its CAPABILITY notes appropriately tell agents to use structured argv calls and trusted runtime-controlled paths.
Install Mechanism
Setup requires npm install in the skill scripts directory with a package lock and ordinary chart-rendering dependencies; this is disclosed and purpose-aligned.
Credentials
Runtime behavior is limited to local chart input parsing and image output; no credentials, account access, background indexing, or external API calls are evidenced in the skill code.
Persistence & Privilege
Persistence is limited to user-directed generated chart files, including documented use of a persistent temp directory for attachments; there is no daemon, scheduler, privilege escalation, or self-modifying behavior.
