Usage Guidance
This skill looks safe for its stated purpose of generating local timeline PNG images. Before installing, ensure you trust the package sources for the recommended fonts and Pillow dependency, and choose output paths carefully so you do not overwrite files unintentionally.
Capability Analysis
Type: OpenClaw Skill Name: timeline-chart Version: 1.0.0 The skill bundle is a legitimate tool for generating timeline chart images using the Python Pillow library. The code in `template.py` performs standard image drawing operations and file saving without any network activity, sensitive data access, or obfuscated logic. The instructions in `SKILL.md` regarding font installation are consistent with the tool's requirement for rendering Chinese characters.
Capability Assessment
Purpose & Capability
The stated purpose is timeline chart generation, and template.py coherently implements a Pillow-based function that draws timeline nodes, cards, text, and saves a PNG.
Instruction Scope
The instructions are limited to using the template function and preparing fonts; there are no goal overrides, hidden agent directives, network actions, credential use, or autonomous workflows.
Install Mechanism
There is no install spec, but SKILL.md documents manual installation of Chinese fonts and a Pillow dependency. This is disclosed and purpose-aligned, but users should install dependencies from trusted sources.
Credentials
The code uses local fonts and writes a user-specified PNG output file. No broad file scanning, network access, credential handling, or unrelated system access is shown.
Persistence & Privilege
The runtime code does not create background services, persistence, or privilege escalation. Optional system font installation is user-directed setup rather than hidden behavior.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install timeline-chart
  3. After installation, invoke the skill by name or use /timeline-chart
  4. Provide required inputs per the skill's parameter spec and get structured output
