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

Annotations already declare a read-only, closed-world operation, and the description adds real value beyond them: it discloses that results are a curated 'best of' selection spanning three geographic tiers and formatted as a printable sheet. It stops short of saying whether items are links, whether results are paginated, or what happens when a topic yields no matches.

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?

A single tight sentence with no waste, front-loading what the agent receives. It is a noun phrase rather than a full statement, which slightly weakens the lead but keeps it efficient.

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 only two parameters, one required, full schema coverage and no output schema, the description covers the essentials: what the sheet contains and how it is scoped geographically. Missing only failure behavior and return shape, which is minor for this complexity.

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%, so both parameters and their constraints are fully documented in the schema. The description reinforces the topic dimension but says nothing about the 'near' parameter that drives the local section, so it adds no meaning beyond the structured fields.

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 names a concrete artifact (a curated sheet of services and resources for one topic) and its scope (local, area-wide and national tiers). It is clear what the tool produces, but it never explicitly distinguishes itself from search_services or get_service, so an agent must infer the curated/packaged nature on its own.

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 phrases "ready-made" and "as a link worker would print" imply this is the packaged alternative to searching manually, but no when-to-use condition or named alternative is stated. An agent can guess the intent but gets no explicit routing rule against siblings like search_services.

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