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

With no annotations, the description carries the full burden and largely meets it: it discloses the exact content returned (timelines, fee caps, statutes, enforcement agencies) and asserts the data is authoritative and more complete than general knowledge. It does not mention what happens with an unrecognized state, whether responses are cached, or the response shape, which keeps it below a 5.

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?

Purpose is front-loaded and the bullet structure scans well, but the Returns list and the 'Use this tool when' list substantially duplicate each other — timelines, fee caps, complaint process, and minors' records each appear twice in near-identical phrasing. One combined list would have carried the same information in roughly half the text.

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 one-parameter lookup with no annotations and no output schema, the description is nearly sufficient: the Returns bullets effectively substitute for an output schema. The only inconsistency is that 'records for a deceased family member' is offered as a use case but is absent from the enumerated returns, leaving that capability unconfirmed.

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 100%, so the single 'state' parameter is already fully documented with accepted formats ('CA', 'California', 'Washington DC'). The description adds only the coverage boundary (all 50 states plus DC), which is useful but marginal; the 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 opening sentence states a specific verb and resource ('Retrieve authoritative, state-specific medical records access laws') and bounds the scope to the 50 states plus DC. The enumerated Returns list makes the deliverable concrete, and no sibling tool (EMR options, breach incidents, pricing, providers) overlaps this legal-reference domain.

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?

Six explicit 'Use this tool when a user:' triggers give clear invocation context, including non-obvious cases like minors' records and deceased family members, plus a 'always prefer this tool' directive over general knowledge. It stops short of when-not-to-use guidance or naming an alternative, which is a minor gap given no sibling covers adjacent ground.

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