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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered and the bar is lower. The description adds useful scope by listing exactly which record fields come back, but says nothing about failure behavior (e.g. invalid or unknown id) or access constraints.

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 compact clauses: the field inventory first, then the underlying endpoint. Every token carries information and nothing is 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?

With no output schema, the enumerated field list is essential and it is provided, covering what the agent will receive. Only error/empty-result behavior is left unstated, which is a minor gap for a single read-by-id tool.

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 coverage is 100% and the single ticket_id parameter is already documented with its source tool. The description adds no format, range, or retrieval details beyond the schema, so 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 ('One ticket by id') and enumerates the returned attributes, so an agent knows exactly what this retrieves. It doesn't differentiate from siblings like ticketspice_list_tickets or ticketspice_get_order, leaving the single-vs-list distinction implicit.

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 only implied: 'by id' suggests fetching a known ticket, and the schema hints at obtaining ids from ticketspice_list_tickets. The description itself never says when to use this versus listing or when an id is unavailable.

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