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

Annotations already declare readOnly, idempotent, closed-world and non-destructive, so the safety profile needs no restating. The description does add genuine content-scope context beyond annotations — that it returns recurring events with usual dates and live availability for those windows, and travel-time estimates rather than raw distance. It says nothing about data freshness or whether the availability figures are a snapshot versus real-time.

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?

One dense sentence with no filler, and the most concrete item (address and coordinates) leads. The trailing list of event and transfer clauses runs together without punctuation hierarchy, making it slightly harder to scan than it needs to be.

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 return shape need not be explained, and the description does cover the breadth of content. What is missing is the operational context an agent needs: how this differs from sibling overview tools, whether the 'live availability' requires a separate call to check_availability, and what the optional category filter does to the result set.

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 coverage is 100% and the single optional 'category' enum filter is fully documented in the schema. The description never mentions the category filter or that omitting it returns all nearby places, so it adds no parameter meaning beyond what the schema already provides. Baseline 3 applies.

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 enumerates the content returned (address/coordinates, walking times, recurring events, live availability, transfer times), so the resource is clear enough. But it is a bare noun phrase with no verb and no scope statement, and it does not distinguish itself from get_property_overview, which plausibly overlaps on address and location detail.

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?

No when-to-use guidance, no exclusions, no mention of alternatives. An agent choosing between this and get_property_overview or check_availability (which the live-availability clause overlaps with) gets no help at all.

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