## Title

    Proposed fix: [Claude Agent SDK Python] ClaudeAgentOptions(skills="my-skill") → TypeError 'must be a list of skill names or "all"... Did you mean [...]' / 'Invalid skill name' validations

## Body

    Recommended action: Pass a list of exact skill directory names (or 'plugin:skill'), or skills="all".
    
    Option: Pass a list of exact skill directory names (or 'plugin:skill'), or skills="all". [evidence: official_recommended_action]
    Applies when: Restricting skills for an SDK agent
    Steps:
    1. skills=["my-skill"] instead of skills="my-skill"
    2. Use skills="all" instead of ["*"]
    3. Use the directory name / plugin:skill form without extra whitespace
    Expected: The error no longer appears.
    
    Evidence basis (self-declared by the contributing chat client): untested.
