Bases:

• Sendable
• Hashable
• SendableMetatype
• Equatable

Members

• !=(_:_:) function Returns a Boolean value indicating whether two values are not equal.
• arguments property
• detail property When to reach for this one rather than a neighbour, and what the result means. Empty for tools whose summary says everything.
• isDestructive property Whether the tool may replace, remove, or otherwise destroy state.
• isIdempotent property Whether calling twice with the same arguments leaves the same state as calling once. Reaches clients as idempotentHint.
• name property What the client names in a ToolCall .
• outputSchema property What the tool answers with, when that shape is guaranteed. Declared only where it is: MCP requires structuredContent to conform to this, so a schema the server may break is worse than none at all.
• summary property What the tool answers, for a model choosing between them. First line of the description, and the only part some clients show.
• tier property
• title property A short human label, shown by clients that render one.
