Does it support both Windows and Linux environments?

Yes, the skill is designed to provide executable commands for both PowerShell (primary) and Bash (fallback) to ensure cross-platform compatibility for validation steps.

How does this skill improve AI reliability?

It uses a six-core framework—Commands, Testing, Project Structure, Code Style, Git Workflow, and Boundaries—to ensure AI assistants have all the context they need to perform tasks without ambiguity.

What files does the Agent Creator skill modify?

This skill specifically targets agent definition files such as agents.md, .github/agents/*.md, and *.agent.md files. It does not modify application source code unless explicitly requested.

What are the safety boundaries used by this skill?

It utilizes a three-tier model: 'Always' for safe tasks, 'Ask first' for sensitive changes like adding dependencies, and 'Never' for destructive actions like force-pushing or deleting tests.

Developer Tools

Architects, reviews, and optimizes agent definition files to ensure clear, executable, and safe AI behavior within any repository.

The Agent Creator skill is a specialized tool for developers looking to define precise operational boundaries and personas for AI assistants. It automates the creation and auditing of agents.md and .agent.md files, converting vague requirements into structured operating manuals. By enforcing a standardized framework that includes executable commands, project-specific knowledge, and a three-tier safety model (Always/Ask first/Never), it ensures that AI agents follow local coding standards and git workflows while preventing destructive actions. This skill is essential for maintaining consistent AI behavior across complex development environments.
