A4.2/5.0

Behavior4/5

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

Beyond the readOnly/idempotent/openWorld annotations, the description discloses the result cap ('up to five listings'), that listings carry source links, the two-mode return (listings vs. category choices), and an explicit scope limitation (no live availability or bookings). It omits any note on rate limits, auth, or what 'prepare' implies about follow-up steps, 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.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with what is found and where, then the return shape, then the exclusion. Every clause carries information; nothing is restated from the title or schema verbatim in a wasteful way.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, the description needn't spell out return fields, and for a 3-parameter read-only search it covers purpose, scope, and limits adequately. The gap is the 'prepare_' prefix, which hints at a preparation or follow-up step that the description never explains, leaving a small ambiguity about whether a second call is expected.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the enum descriptions already explain category values, the no-category behavior, language codes, and the location format. The description reinforces category behavior and the five-listing cap but adds no new syntax or format guidance, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Find') and a specific resource ('public MYOPL pickleball courts, clubs and open play league listings') plus the scoping input (city, state or country). The resource is clearly distinct from the sibling tools (ratings, help, website search, rules), so an agent can route correctly without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage context is clear: use it for a geographic lookup, and if no category is selected it returns category choices rather than listings, which tells the agent how to bootstrap. It also states an exclusion ('live availability and bookings are not included'), but it never names an alternative tool for bookings or availability, so the routing guidance stops short of explicit when-not/use-instead.

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