Photos For Place

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safe-read nature is covered. The description adds useful extra context with the $0.10 cost and API-key requirement, and it scopes behavior to 'canonical place' assets, but it discloses little beyond those points.

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 compact and includes both cost and auth context in a single sentence. However, it reads as a noun phrase rather than a complete operational description, so it is concise but slightly under-specified.

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?

The tool is simple with one parameter and an output schema, and annotations cover the read-only safety profile. Still, the description omits any usage context or parameter clarification, so the agent is left to infer details that could help correct invocation, especially among many similar photographic and place-related tools.

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 0%, so the description must compensate for the undocumented place_id parameter, but it never mentions place_id or explains what canonical place ID format is expected. While the parameter name is somewhat self-evident, the description adds no semantic value beyond the schema.

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 resource scope ('Assets linked to a canonical place') but lacks an explicit verb such as 'retrieves' or 'returns'; the operation is mostly carried by the tool name. It also does not distinguish this from sibling tools like get_photos_for_event, get_person_photos, or get_place_visits, so an agent must infer what makes this tool unique.

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?

There is no guidance about when to use this tool versus alternatives. The only added context is cost and API-key requirements, which do not help an agent choose between get_photos_for_place, get_photos_for_event, or search_photos. No exclusions or conditions are stated.

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