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

The annotations already establish this as a safe, idempotent read operation. The description adds useful behavioral context by specifying what is returned, including latest comments ordered newest first, which helps an agent understand the response without an output schema.

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 a single front-loaded sentence that efficiently lists the key returned fields. It is appropriately sized, though the parenthetical slightly interrupts the field list.

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?

Because there is no output schema, the enumeration of returned fields is valuable and mostly sufficient for a simple read tool. However, it leaves gaps around ticket_id semantics, comment count defaults, and error behavior for missing tickets.

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 only 50%, and the description does not compensate for the undocumented ticket_id parameter or explain ticket identifier format. It only indirectly references comments via 'latest comments (newest first)' and omits the count/default behavior documented in the schema.

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 this retrieves details for one ticket and enumerates the returned fields, so the resource and scope are unambiguous. It does not explicitly contrast with sibling tools like search_tickets or my_tickets, which keeps it from a 5.

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?

There is no explicit guidance on when to use this tool versus search_tickets, my_tickets, or get_project. The single-ticket scope implies intended use, but alternatives and exclusions are absent.

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