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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered by structured data. The description reinforces this with "does not create a booking" and adds topical scope (services plus legal limitations), but says nothing about response shape, length, or whether the legal content is jurisdiction-specific.

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 sentence with the positive scope front-loaded and the negative boundary appended; no filler or redundancy. Every clause carries information.

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 zero-parameter, non-destructive informational tool with no output schema, stating the two content domains is nearly sufficient to call it correctly. The remaining gap is that the description does not characterize the return format, which matters slightly more here because no output schema exists.

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 and the schema coverage is 100%, so there is nothing for the description to disambiguate. A baseline 4 is appropriate for a parameterless definition.

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 uses a specific verb ("Describe") with a named resource scope ("OlaHome services and legal limitations"), which is clearly distinct from the property-oriented siblings get_property_details and search_properties. It does not explicitly name those siblings to route the agent, but the topical split is inferable from the wording.

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 clause "does not create a booking" implicitly marks a when-not boundary and steers the agent away from transactional intent. However, it never names an alternative tool for booking or for property lookups, so the when-to-use guidance is only implied rather than stated.

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