Parent, children and tracker of a ticket

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

Annotations already declare readOnlyHint=true and destructiveHint=false, covering the safety profile. The description adds semantic context about what related tickets mean, but does not disclose additional behavioral traits such as return format or pagination.

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 two sentences long and efficiently conveys the core concept and a use case. Each sentence adds value, with no redundant information.

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 simplicity of the tool (one parameter, no output schema) and the availability of annotations, the description is reasonably complete. However, it leaves ambiguity about the exact return type and the directionality of relationships (e.g., whether both parent and children are included), which could confuse an agent.

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?

The schema has one parameter (ticket_id) with 0% description coverage. The description implies that 'this one' refers to the given ticket ID, providing some context, but it does not explicitly explain the parameter's purpose or constraints beyond what the schema defines.

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 identifies the resource (related tickets) and the relationship concept (parent/children/tracker), but it lacks a direct verb like 'retrieves' or 'lists'. It distinguishes itself from sibling tools by focusing on linked tickets rather than general ticket data.

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 clear context for when to use the tool (e.g., recurring incidents, finding the tracker for a tracked ticket) but does not explicitly mention alternatives or exclusions. The use case is illustrated with the 'recurring incident' example, making the intended scenario clear.

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