  - Skills are model-invoked successfully (Claude can use them)

> what skills are available?

⏺ Ryan, I can see the available skills by checking the Skill tool's documentation. Based on the tool definition I have access to, here are the currently available skills:

  Available Skills

  1. argc (user skill)
    - Description: Create and modify Argcfiles using the special syntax required
    - Use when: Editing Argcfile.sh, @argc, or any shell script that contains argc --argc-eval
    - Location: user

  That's the only skill currently installed in your Claude Code configuration.

  Skills are typically invoked using the slash command syntax (e.g., /argc), though there are also built-in slash commands like /help and /clear that are part of the CLI itself rather than being user-defined skills.

  If you're looking to add more skills or want to know about built-in capabilities, I can help you explore the documentation or check what other options are available.
