get_library_sections_by_section_id_arts

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

Annotations declare readOnlyHint=true and destructiveHint=false, but the description explicitly says 'Set section artwork,' contradicting the read-only behavior. No additional behavioral context is provided beyond the annotations, and the contradiction makes the description harmful.

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 short, but its main sentence is misleading and the 'Args' section adds no value beyond the schema. This is under-specification with harmful content, not effective conciseness.

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 the tool is simple with one parameter, the misleading purpose and lack of any usage or behavioral context make it incomplete. The annotations cover safety, but the description fails to explain what this endpoint actually retrieves or when it should be used.

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 compensate, but it merely restates the parameter as 'section_id: Section identifier,' which duplicates the schema's title 'Section Id.' No additional meaning, format, or constraints are provided.

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 begins with 'Set section artwork,' which implies a write operation, but the endpoint line says 'GET /library/sections/{sectionId}/arts,' indicating a read operation. This is actively misleading rather than clarifying. The description does not distinguish this from sibling tools like create_library_metadata_by_id_arts or get_library_sections_by_section_id_settings.

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?

No guidance is given about when to use this tool versus alternatives. There is no mention of context, exclusions, or related sibling tools. The misleading 'Set' verb also creates a wrong assumption about its use.

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