list_album_photos

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

No annotations are provided, so the description carries the burden. It mentions the URL format (1024px static) which is helpful, but fails to disclose pagination behavior (page, per_page), ordering, or any constraints. The description adds some value but lacks important behavioral details.

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 concise sentences: first states purpose, second adds return details. No unnecessary words. Front-loaded with the primary action.

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?

Given 3 parameters with pagination, the description omits pagination details. Output schema exists, so return fields are likely covered, but the description should mention that results are paginated and how to control it. Adequate but not complete.

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 explain parameters. It does not describe 'album_id', 'page', or 'per_page' beyond what the schema provides. The description only covers return values, leaving parameter semantics unclear.

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 'List' and resource 'photos in an album', and specifies the returned fields (id, title, URL). It distinguishes from sibling tools like 'list_albums' (list albums) and 'search_photos' (search).

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?

Usage is implied: use to list photos in an album. No explicit when-to-use, when-not-to-use, or alternative tools mentioned. The description lacks guidance for differentiation from siblings like 'get_photo_info'.

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