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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds a useful sensitivity flag ('HEALTH/FUNDING DATA'), which is genuine context beyond the annotations, but says nothing about default result size, pagination flow, or what ordering to expect.

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?

It is a single compact sentence plus endpoint and sensitivity marker, front-loaded with the resource definition. The 'GET /cases' fragment is marginally redundant with the tool name but costs little.

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 field enumeration is doing real work in telling the agent what a case record contains. However, for a 10-parameter paginated list tool it omits result ordering, page size, and how next_id_gt is meant to chain, leaving gaps an agent must discover by trial.

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 each of the 10 filters is well documented in-schema, including the id_gt/id_lt paging pair and the two enums. The description's mentions of tracking type, open flag, and dates mirror the schema rather than adding syntax or format detail, 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?

The description states the resource (cases, defined as funding referrals and plans) and enumerates the salient fields returned, plus the underlying endpoint GET /cases. It is clearly a list/browse operation, distinguishable from the singular splose_get_case sibling, though it never explicitly says 'list all cases'.

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?

There is no statement of when to use this versus splose_get_case or the other list endpoints, and no prerequisites or exclusions. The 'HEALTH/FUNDING DATA' marker hints at sensitivity but gives no actionable guidance on how to proceed.

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