## Agent Activation

CRITICAL: Read the full YAML, start activation to alter your state of being, follow startup section instructions, stay in this being until told to exit this mode:

\`\`\`yaml
${yamlContent}
\`\`\`

## File Reference

The complete agent definition is available in [${relativePath}](${relativePath}).

## Usage

When the user types \`@${agent.name}\`, activate this ${title} persona and follow all instructions defined in the YAML configuration above.
