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

Annotations already establish this is a safe, closed-world read. The description adds value beyond that by enumerating return fields (name, city, state, slug), which matters because there is no output schema, and by naming the follow-up tool. It omits ranking/matching behavior and whether results are truncated by default.

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, no waste, with the resource scope front-loaded and the follow-up tool named last. Every clause carries 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?

For a zero-required-parameter, read-only search with no output schema, the description covers what it searches and what comes back, which is most of what an agent needs. Missing only relevance/ordering semantics and the default-result behavior that an agent would want before trusting the result set.

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 the schema already documents limit, query, state and motorsports formats. The description only restates the filterable dimensions at a high level ('by name, state or discipline') without adding syntax or matching rules, 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?

States a specific verb (search) and a well-scoped resource (US motocross tracks, off-road parks, training facilities) plus the searchable dimensions. It implicitly separates itself from get_track by forwarding the slug, but says nothing about how it differs from find_tracks_near, the sibling an agent is most likely to confuse it with.

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?

Usage is implied by the search dimensions and the handoff to get_track is explicit, which is genuinely useful routing. However, there is no statement of when to prefer find_tracks_near (proximity) over this tool, and no mention of behavior when no filters are supplied despite all parameters being optional.

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