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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is covered. The description adds genuinely new behavioral context that the scope is auto-limited to the caller's own customer, which prevents the agent from looking for a customer filter. It omits pagination behavior, default limit, and result ordering, which matter for a list tool.

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, filter capability stated first and the scoping constraint second. No filler; every clause carries information the agent needs.

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 6-optional-parameter list tool with no output schema, the description covers purpose and scope but leaves out default/maximum limit behavior and any hint about what a returned ticket contains. Annotations cover the read-only profile, so the remaining gap is mostly pagination and parameter value semantics.

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 0%, so the description carries the full burden, yet it only echoes the parameter names (status/priority/area/type/project) without defining valid values, expected formats, or scope for area and type. The limit parameter is not mentioned at all, and the description says "project" while the schema key is project_id, leaving the mapping implicit.

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?

Specific verb+resource ("List support tickets") plus the filter dimensions, which clearly separates it from get_support_ticket and file_support_ticket in the sibling set. It stops short of naming those siblings, so the differentiation is inferable rather than explicit.

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 implies browsing/filtering use, and "Scoped to your own customer automatically" tells the agent it needn't pass a customer identifier. But there is no explicit guidance on when to use this versus get_support_ticket for a single ticket, nor on how to handle pagination or result volume.

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