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

Annotations already declare readOnlyHint=true, so the safety profile is covered by structured data. The description adds the underlying endpoint (GET /v1/tickets/{ticketId}), which is mildly useful for orientation, but says nothing about what is returned, error behavior for unknown ids, or auth requirements.

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, no filler, with the core action front-loaded before the endpoint detail. Appropriately sized for a simple single-record getter, though the endpoint clause is of marginal value to an agent that cannot call REST directly.

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 read-only lookup with full schema coverage and a readOnlyHint annotation, the description provides everything needed to invoke it correctly. The absence of a description of the returned ticket fields is a minor gap given no output schema exists.

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 100% and the single parameter already documents the uuid format and its origin in gorelo_list_tickets. The description only restates the type hint, adding no format or sourcing detail beyond the schema, 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 ('Get one ticket by id') and pins the identifier format as uuid, which cleanly separates it from gorelo_list_tickets. It stops short of naming the sibling alternatives explicitly, but the 'one ticket by id' framing makes the retrieval-vs-list distinction unambiguous.

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?

Usage is implied rather than stated: an agent can infer this is the single-record fetch counterpart to the list tool, and the schema note 'from gorelo_list_tickets' supplies the id source. There is no explicit when-to-use/when-not statement or discussion of alternatives in the description itself.

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