get_image

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

With no annotations, the description carries the burden for behavioral disclosure. It lists the output fields, which is useful, but does not mention error behavior, read-only nature, or any side effects. The return-value disclosure is partial but present.

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 sentence, front-loaded with the core action ('Full metadata for one image') and a concise enumeration of fields. Every word adds value; no redundancy or filler.

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 one-parameter getter, the description covers the essential context: what the tool returns and the scope. It omits edge cases (e.g., not-found behavior) but is reasonably complete given the tool's simplicity, especially when no output schema is provided.

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 0% description coverage for the only parameter image_id. The description only says 'for one image,' which barely reinforces the parameter's purpose. It does not explain the format, source, or how to obtain the ID, so it fails to compensate for the absent schema documentation.

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 states the verb ('get') and resource ('image'), and specifies the scope ('one image') with a list of metadata fields ('path, EXIF, rating, flag, edit status'). This distinguishes it from siblings like list_images (multiple images) and get_current_image (current image, not specific).

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 description implies usage context: when you need full metadata for a single identified image. However, it does not explicitly mention when to prefer this over list_images or get_current_image, nor does it state any alternative or exclusion.

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