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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the agent knows this is a safe read operation. The description adds that it returns a JSON object and specifies required parameters, which is useful but does not significantly extend beyond annotations. No contradiction.

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?

Description is two concise sentences plus a line with API details. It is front-loaded with the main purpose and required parameters. Every sentence adds value, though the API endpoint line is more for developer context.

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?

No output schema exists, so the description should describe return values more thoroughly, but it only says 'Returns a JSON object describing the requested Photos.' It does not explain pagination parameters (page, per_page) or when to use them. Given the large number of sibling tools, more context on differentiation would be beneficial.

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?

Input schema has 100% description coverage for all 4 parameters, so the schema already documents them well. The description mentions required parameters (id, project_id) and the API endpoint, but does not add new meaning beyond what the schema provides. Baseline of 3 is appropriate.

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?

Description clearly states the action ('Return detail information') and the resource ('Photo Album (Image Category)'). It also specifies required parameters and API endpoint, making the purpose explicit. However, it does not differentiate from sibling tools like list_image_categories or update_image_category.

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 provides a use case ('fetch the full details of a specific Photos'), but does not mention when not to use this tool or suggest alternative tools for different needs. No exclusions or comparisons are given.

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