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

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered structurally. The description adds no behavioral context at all (no pagination, filtering, or shape of the returned relationship data), leaving it entirely redundant with the annotations.

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 meaningful sentence is duplicated verbatim, and the opaque operation ID plus schema pointer consume the rest of the text. There is no front-loaded explanation of what is returned, so the length is repetition rather than 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?

There is no output schema, so the description was the only place to explain what a 'date relationship' record contains, and it does not. Combined with 0% parameter documentation and a nested query object, an agent cannot determine what it will receive or how to shape the call.

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 is responsible for compensating and does not. The required `params.id` and the free-form `query` object (additionalProperties with no constraints) are entirely undocumented; only the URL path implicitly hints that `id` is a lease id.

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 only restates the endpoint path verbatim (twice), so it adds nothing beyond the tool name. An agent can infer 'fetch date relationships for a lease id', but the term 'date-relationships' is never defined and there is no differentiation from the many sibling lease sub-resource getters (e.g. get_leases_by_id_field_date_relationshi...).

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 guidance on when to use this versus alternatives; the only directional hint is that describe_operation 'provides native request schemas', which points to another tool for schema detail rather than to usage context. No prerequisites, no exclusions, no described scenario.

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