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

Annotations already declare destructiveHint=true and a title, so the safety bar is lower. The description adds the useful precondition that the ticket must be closed and identifies the underlying endpoint, but says nothing about side effects (status change, notifications), permissions, or failure behavior when the ticket is not closed.

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?

Two short sentences, action and endpoint, with the core purpose front-loaded. Nothing redundant or padded.

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?

For a one-parameter state-change tool with no output schema, the description covers what an agent needs to call it: the target resource, the precondition, and the endpoint. It is only slightly thin on post-call behavior, which the annotations partially cover.

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 a single parameter and 100% schema description coverage, the schema already documents ticket_id fully. The description adds no format, range, or sourcing detail beyond what the schema provides, so the baseline 3 applies.

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?

States a specific verb and resource ('Reopen a closed ticket') and the precondition (must be closed), which implicitly separates it from siblings like trengo_close_ticket. It does not name an alternative tool explicitly, so it falls just short of the top mark.

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 phrase 'a closed ticket' implies when the tool applies, but there is no explicit when-to-use guidance, no statement of what to do instead (e.g., close_ticket, send_ticket_message) and no exclusions. Usage must be inferred.

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