Introducing Claude Subagent Install Manager

The truecast tool lets you install specialized personas in Claude Code. These are pre-built sets of instructions and knowledge for roles like product manager, architect, or security expert.

Each persona has a core from the author that can be updated, and an instance for your specific project. Your local project notes and instructions stay separate and intact when the agent skills update.

You can install a persona via CLI with `truecast install`. Once installed, the agent is available in Claude Code as a subagent via the mention `@agent-<name>`. You can also run the persona as a standalone agent with `claudemux`.
