create_ticket_tool

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description only states the action and parameters; it doesn't mention side effects, permissions required, whether the ticket is created in a specific state, or what happens on success/failure. For a creation tool, this is a significant gap—an agent doesn't know if this is a safe read-only operation or a mutating one (though 'create' implies mutation).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and front-loaded with the purpose statement, followed by a clean parameter list. Every sentence earns its place. The only minor issue is that the parameter list format (Args:) is a bit terse but acceptable for a tool with only four parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It doesn't explain what the tool returns (e.g., ticket ID), whether the customer must exist (though 'existing customer' implies it), or any error conditions. For a creation tool with multiple sibling tools, more context is needed for an agent to invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. The description does list all four parameters with brief explanations (customer_id, subject, description, priority), which adds meaning beyond the bare schema titles. However, it doesn't provide format details (e.g., expected length of subject, whether priority is case-sensitive) or clarify that priority has a default of 'medium' (which the schema shows but the description omits).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Create a support ticket for an existing customer.' It uses a specific verb ('create') and resource ('support ticket'), and the 'existing customer' qualifier distinguishes it from create_customer_tool. However, it doesn't explicitly differentiate from other ticket-related tools like assign_ticket_tool or add_comment_tool, though the verb 'create' makes the primary purpose clear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context by specifying 'for an existing customer,' which suggests it should not be used for new customers. However, it doesn't explicitly state when to use this tool versus alternatives like create_customer_tool or assign_ticket_tool. The sibling list includes several ticket-related tools, but no explicit routing guidance is provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
