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

With no annotations, the description must convey safety and behavior; 'Search' signals a read-only operation and the return fields are listed, but it does not disclose pagination, sorting, match behavior, or any access requirements. Acceptable but minimal.

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?

Two sentences, each earning its place: first defines action and scope, second names what is returned and links to get_track. No filler or redundancy.

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 search tool with no output schema or annotations, the description covers purpose, scope, and return fields, but omits guidance about the location-based sibling, whether at least one filter is required, and result ordering/pagination beyond the schema's default.

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?

All 4 parameters are fully described in the schema, so the baseline is 3. The description adds some context by naming the three search criteria, but uses 'discipline' where the schema calls it 'motorsports' and adds no new detail about limit or query semantics.

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?

Clearly states a specific action (search) on a defined resource (US motocross tracks, off-road parks, training facilities) with explicit search dimensions (name, state, discipline). It also points to get_track via slug, but does not explicitly contrast with the location-based sibling find_tracks_near, so it's not a full 5.

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 description implies the search-to-get_track flow by mentioning the slug, but gives no explicit when-to-use or when-not-to-use guidance, and is silent on the location-based alternative find_tracks_near.

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