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

Annotations already establish readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds real value by disclosing the content of each record, including the 'application search' versus 'coming soon' status flag, which is behaviorally meaningful and not derivable from the schema.

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?

A single front-loaded sentence with no filler — the scope (LA furnished homes) comes first, then the per-region contents. It is slightly run-on, stacking page, description, neighborhoods, and status into one breath, but every clause earns its place.

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?

With no output schema, the description carries the burden of explaining what comes back, and it does so adequately: region entries with page, description, neighborhoods, and availability status. For a small, non-paginated, read-only catalog lookup, that is essentially complete.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a no-param tool is 4. Nothing in the description misleads about inputs.

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 states a specific resource (regions/neighborhoods where heidi.living has furnished monthly homes in LA) and enumerates what each entry carries: page, description, neighborhoods, and application-search availability. It is far more specific than the title, though it never explicitly contrasts itself with the siblings application_link and faq.

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 only implied: an agent can infer this is the lookup for which regions/neighborhoods are live versus 'coming soon.' There is no explicit when-to-use statement, no pointer to application_link or faq as follow-ups, and no exclusions.

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