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

The annotations already establish that this is a safe, read-only, non-destructive operation. The description adds that it returns a download link intended for sharing, but it does not disclose link expiration, permissions, or other behavioral details beyond that.

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 description is a single front-loaded sentence with no unnecessary filler. The parenthetical "(or multiple guides')" is slightly awkward but still clarifies scope efficiently.

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 read-only tool with full schema coverage and annotations covering safety, the description sufficiently states that it returns a shareable download link. It does not need an output schema, though it could mention link behavior or error cases.

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 both parameters are fully documented in the schema with prerequisite and source instructions. The description adds no parameter-level meaning beyond noting that one or multiple guides can be requested, so the baseline of 3 is appropriate.

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 ("Retrieve") and resource ("real estate guide's ... download link") and clarifies that it can handle one or multiple guides. It does not explicitly differentiate itself from the sibling get_guides_list tool, which is used to discover guide IDs.

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 phrase "for the agent to share with the user" implies the use case, but there is no explicit guidance on when to use this tool versus get_guides_list or other siblings. The schema provides prerequisite instructions, but the description itself offers only implied usage context.

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