get_photo_metadata

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It does specify the content scope of the response (which metadata categories are included), which is useful. However, it does not explicitly state that the operation is read-only, what happens with an invalid/nonexistent photo_id, or whether any authentication or Lightroom session is required.

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 that leads with the action and then lists specific metadata categories. There is no filler or repetition; every word contributes value.

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 a simple one-parameter getter, and an output schema exists, so explaining return values in the description is not necessary. However, the absence of usage routing and photo_id semantics leaves meaningful gaps, especially with no annotations to fill the safety/behavior role. The definition is minimally adequate but not fully helpful.

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 schema has one parameter (photo_id) with no description at all (0% coverage). The description only says 'for a photo,' adding negligible meaning. It does not explain how to obtain a photo_id, what formats are accepted (though the schema allows string/integer), or whether the ID refers to a Lightroom catalog ID or an external reference.

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 ('Get') and a clearly delineated resource ('detailed metadata for a photo') while enumerating the exact categories of metadata returned (EXIF, camera, lens, dimensions, develop parameters). This unambiguously distinguishes the tool from sibling tools like search_photos, list_collections, or set_develop_settings.

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 on when to use this tool vs. alternatives. The description does not mention prerequisites (e.g., needing a valid photo_id), nor does it distinguish get_photo_metadata from its sibling lightroom_get_photo_metadata or from list/search tools. The agent is left to infer usage from the tool name alone.

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