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

Annotations already establish the read-only, non-destructive, closed-world safety profile, so the bar is lower. The description adds real value by describing the shape of what comes back (photo plus tagged service plus booking link), which matters since there is no output schema. It doesn't mention pagination, empty galleries, or ordered results.

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?

Two sentences, front-loaded with what the tool returns, followed by the use case. The parenthetical examples of work types are illustrative rather than filler, and nothing is redundant.

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 two-parameter read tool with full schema coverage and no output schema, the description covers both the return content and the selection intent. Only minor operational details (paging, empty results) are missing, which is acceptable here.

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%, so both business and location_id are already documented, including the default-first-location behavior. The description adds only implicit meaning (the gallery belongs to that business/location) and no format or edge-case detail, so 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 clearly identifies the resource (photos the business displays on its booking page) and enriches it with what each entry carries: a tagged service and a booking link. It doesn't explicitly distinguish itself from siblings like get_about or list_services, but the resource is specific enough that an agent can tell it apart.

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?

It gives two concrete user intents ("can I see their work?" and "do they do this style?") that map cleanly to when this tool is the right pick. It stops short of naming alternatives or exclusions, so it lands at clear context without full routing guidance.

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