List Philadelphia Neighborhoods

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered structurally. The description adds only the filter-discovery framing; it says nothing about pagination, result size, or response shape, so it earns limited additional credit.

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 short sentences with the action front-loaded and the usage hint second. No wasted phrasing, though the second sentence is mild restatement of the first.

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 trivial, annotation-covered, parameter-free discovery tool with no output schema, purpose and usage are adequately covered. The missing piece is any mention of the response_format choice's effect on output.

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 0% and the single response_format parameter (json/markdown) is never mentioned in the description. Although the enum values are self-explanatory, the description does nothing to compensate for the absent schema descriptions, so it falls below the 3 baseline.

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+resource ('List all recognized Philadelphia neighborhoods') and scopes it to event filtering, which differentiates it from philly_list_categories by resource. It does not explicitly say how it differs from the other siblings, but the noun phrase is unambiguous.

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?

'Use this to discover what neighborhood filters are available' gives a clear positive use case. There is no when-not guidance and no alternative tool is named, so the routing decision relies on the agent inferring that this is a prerequisite/discovery step.

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