Does this skill work with any AI model?

It is designed for use within the Claude Code ecosystem and requires the ai-core and ai-chat skills to provide model access and chat routing.

Can I add my own custom tools to this framework?

Absolutely. The skill establishes a central tool registry in the src/lib/ai/tools directory where you can easily export and register additional custom tools.

Does the datetime tool handle daylight savings and offsets?

Yes, it utilizes the native Intl.DateTimeFormat API with support for IANA timezone names to accurately calculate local times, offsets, and formatted dates.

Is the calculator tool safe to use in a production environment?

Yes, it uses a custom tokenizer and AST parser instead of the standard JavaScript eval() function to prevent code injection and ensure security.

What UI library is required for the tool cards?

The ToolInvocationCard component is built for React and utilizes Phosphor Icons for its visual states, matching the design of modern AI interfaces.
