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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered without the description. The description adds provenance context ('each with who published it') and payload scope, which is mildly useful. It lists return contents rather than behavior, and says nothing about missing-record handling or island-specific differences beyond the odd 'Kiawah and Seabrook:' scoping.

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?

The purpose is front-loaded in the first clause, which is good. However the remainder is a long run-on enumeration of payload fields, much of which duplicates what the existing output schema already conveys, and 'Kiawah and Seabrook:' dangles without a clear predicate.

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?

An output schema exists, so the description is under no obligation to explain return values — yet it spends nearly all its words doing exactly that. The genuinely useful gaps (when to prefer this over list_neighborhoods or island_market, and what happens on a name miss) remain unaddressed. Adequate, but with clear gaps for a two-required-parameter lookup tool.

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 100% and the island enum is fully documented in the schema (including the Johns Island caveat), so the baseline is 3. The description contributes no parameter-level guidance — it neither explains the name/slug acceptance rules nor how island interacts with name resolution. Nothing is added beyond the schema.

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 makes clear this retrieves a single neighborhood's record and enumerates its contents (sourced facts, regime manager, homes/lots, MLS sales, CMA range, fee ledger, page URL). It is distinguishable from list_neighborhoods and island_market by the singular 'one neighborhood' framing. The verb is implied rather than stated ('One neighborhood's record' is close to restating the title), so it stops short of a 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?

There is no explicit when-to-use instruction, no prerequisites, and no named alternative among the ten siblings. The agent can infer it is the detail-lookup counterpart to list_neighborhoods, but this is left entirely to inference. No exclusions or boundary conditions are given.

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