What it does

Generated summary from the skill's own text

Invokes available skills within the agent by name, allowing delegation to specialized capabilities and domain knowledge when users request specific tasks or reference slash commands like /commit or /review-pr.

When to use it

  • User requests a task matching an available skill name
  • User references a slash command or /something syntax
  • Task requires specialized domain knowledge or capabilities
  • User asks to perform a named operation like commit or review

When not to

  • Invoking built-in CLI commands like /help or /clear
  • Skill is already running in the current context
  • No matching skill exists for the user's request

These commands install from the publisher's repository and need no account.

# Skill

Execute a skill within the main conversation

When users ask you to perform tasks, check if any of the available skills match. Skills provide specialized capabilities and domain knowledge.

When users reference a "slash command" or "/<something>" (e.g., "/commit", "/review-pr"), they are referring to a skill. Use this tool to invoke it.

How to invoke:
- Use this tool with only the skill name
- Examples:
  - `skill: "pdf"` - invoke the pdf skill
  - `skill: "commit"` - invoke the commit skill
  - `skill: "review-pr"` - invoke the review-pr skill
  - `skill: "ms-office-suite:pdf"` - invoke using fully qualified name

Important:
- Available skills are included in your current prompt context in the conversation
- When a skill matches the user's request, this is a BLOCKING REQUIREMENT: invoke the relevant Skill tool BEFORE generating any other response about the task
- NEVER mention a skill without actually calling this tool
- Do not invoke a skill that is already running
- Do not use this tool for built-in CLI commands (like /help, /clear, etc.)
- If you see a <command-name> tag in the current conversation turn, the skill has ALREADY been loaded - follow the instructions directly instead of calling this tool again
