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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered structurally. The description adds nothing beyond that: no note on auth requirements, error behavior, or whether a determination can be missing/404 for an unknown lease.

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 single content sentence is duplicated verbatim, which is pure waste, and the remaining line is an operation ID plus a pointer to another tool rather than front-loaded purpose 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?

For a nested-object, zero-coverage-schema tool with no output schema, the description leaves an agent unable to predict request shape or return content. It supplies neither parameter meaning nor the response structure that the absent output schema would otherwise provide.

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% for two parameters, so the description must compensate and does not. It never explains that leaseId is a path parameter with a 1-2000 char constraint, nor what the free-form 'query' object accepts (filters, expansion flags, version selectors).

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 restates the HTTP path in the title/name twice ('GET /api/lease-determination/:leaseId. GET /api/lease-determination/:leaseId.') without saying what a lease determination actually is or what the response contains. The verb is only the HTTP method, so an agent learns the resource name but nothing about its semantics or how it differs from sibling tools like get_lease_determination_by_leaseId_snap.

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?

No statement of when to use this tool, when not to, or which sibling to prefer. The only actionable hint is the pointer to describe_operation for native request schemas, which addresses schema discovery rather than tool selection.

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