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

The description adds significant behavioral detail beyond annotations. It explains handling of sensitive data (do not echo), the secure payment flow via card_form_url, and the semantics of payment_approved values. These are operational behaviors not captured in the annotations, which only indicate readOnly=false and destructiveHint=true. No contradiction exists.

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 well-structured with a clear opening line followed by scoped paragraphs for each use case. It is information-dense without being verbose, and the most critical safety guidance (sensitive handling) appears early. Slightly long for the average tool, but justified by the complexity of the behavior.

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's complexity (7 parameters, multiple workflows including sensitive data and payments), the description covers the major scenarios and parameter semantics. It does not explicitly mention the 'message' parameter, but the output schema exists (as indicated) which might clarify return values. The description is largely complete for the agent to call the tool correctly, though a few minor gaps remain (e.g., field/value legacy parameters).

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?

With 0% schema description coverage, the description must carry the burden of explaining parameters. It clearly explains sensitive, field_values, and payment_approved, and mentions 'value' in the context of not echoing. However, it does not explicitly define 'field' and 'value' parameters, though their names are relatively self-explanatory. Overall, the description compensates well for the schema gap but leaves a few parameters under-specified.

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 begins with a clear, specific verb and resource: 'Resume a ticket waiting on the user.' This immediately distinguishes it from siblings like cancel, get_action_ticket, or invoke_action. The purpose is unambiguous and contextually unique.

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 provides explicit when-to-use conditions for various scenarios (sensitive prompts, info requests, payment approvals). However, it does not explicitly name alternative tools or state when not to use this tool. The usage context is clear enough that an agent can infer appropriate invocation, but exclusionary guidance is missing.

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