get_library_sections_by_section_id_cluster

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

The description contradicts the annotations: 'Set' implies a write, while readOnlyHint=true and destructiveHint=false indicate a safe read. The GET endpoint supports read-only, but the description's phrasing is inconsistent. No additional behavioral context (e.g., return format, limitations) is provided.

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 extremely short)Skip and not well-structured. The first sentence 'Set section clusters.' is not only misleading but also cluttered with an unnecessary blank line and a redundant restatement of the endpoint that already appears in the tool name. The args section is minimal at best.

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?

Even though an output schema exists, the description is too sparse to be useful. It does not explain what a 'cluster' represents, what operation the GET performs, or how this relates to sibling tools. The contradiction between 'Set' and the GET endpoint further undermines completeness.

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 description's parameter line 'section_id: Section identifier' merely restates the schema's title 'Section Id' without adding any new meaning. With 0% schema description coverage, the description was expected to explain the parameter more deeply but failed to do so.

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 opens with 'Set section clusters,' which incorrectly implies a mutating operation, while the tool name, endpoint (GET), and annotations all indicate a read-only retrieval. The verb is misleading rather than informative. It does not distinguish this tool from any of the many sibling library section endpoints.

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 call this tool versus any of the dozens of sibling endpoints. The description provides no context, such as what a 'cluster' is or how it differs from 'all', 'albums', or 'collections'. An agent would have no basis to select this tool over alternatives.

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