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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds behavioral context beyond annotations: it returns only object IDs (not full metadata), supports pagination, and notes CC0 public domain. It also funnels subsequent calls to met.details. No contradictions found.

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?

Three sentences with each earning its place: first defines the operation, second explains return type and downstream workflow, third notes licensing and adds example context. No redundant words or filler. Well-structured and front-loaded.

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 3 parametersaging. The description covers the core behavior (browse, paginate, return IDs), gives the next step (met.details), and references met.departments for valid IDs. Given annotations and the presence of an output schema, it is sufficient for an agent to invoke correctly. Minor omission: no explicit discussion of edge cases like invalid department_id or pagination limits beyond schema defaults, but these are not critical for basic use.

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 100%, with each parameter (department_id, page, per_page) well-documented. The description reinforces department_id usage by mentioning met.departments and giving example IDs, but these examples already appear in the schema. It adds little beyond what the schema already provides, meeting the baseline for full schema coverage.

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 specific verb ('Browse'), a clear resource ('all artworks in a Met Museum department'), and a key parameter ('by department ID') plus pagination. It also explicitly differentiates from siblings by directing to met.details for metadata and met.departments for IDs, making it unambiguous what this tool does.

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 clearly tells when to use the tool: to browse all artworks in a department. It explicitly names the related tools met.details (for metadata) and met.departments (for IDs), showing the workflow. It does not explicitly mention when NOT to use it (e.g., compared to met.art.search), but the browsing purpose and sibling reference cover the main alternatives.

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