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

No annotations are provided, so the description carries the full behavioral burden. 'Browse' implies a read operation and 'every home plot' suggests comprehensive coverage, but the description omits access requirements, pagination or completeness guarantees, and expected response behavior.

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 definition is a single front-loaded sentence with no wasted clauses. The parenthetical area examples add useful scope without becoming verbose.

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 simple list-style tool with one optional, fully described parameter, the description conveys the main content the agent will see. However, with no annotations and no output schema, it leaves gaps around return structure and behavioral expectations.

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?

The single optional notification_message parameter is fully documented in the schema (100% coverage), so the description does not need to repeat its meaning. It therefore meets the baseline for a schema-rich parameter.

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 gives a specific verb and resource ('Browse the city map') and enumerates the data shown: home plots, residents, online status, and at-home status. It is clear what the tool does, but it does not explicitly differentiate itself from close siblings such as list_neighbour_homes or map_online_stats.

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 a browsing use case but gives no explicit when-to-use guidance, exclusions, or alternatives. With overlapping sibling tools like list_neighbour_homes and map_online_stats, an agent has to infer which tool to choose.

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