Get home catalog settings

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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint, covering safety and side-effect behavior. The description adds minimal behavioral context beyond restating the purpose (reading catalog settings), which is already in the name. It doesn't describe return format or potential limitations, but the annotations carry the safety burden, so a 3 is appropriate.

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 a single, front-loaded sentence with no filler. It efficiently states the operation and scope without redundancy, making it easy to scan and understand.

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 has no output schema, so the description should explain what the tool returns. It only says it 'reads' the configuration but doesn't describe the structure or content of the returned data. Additionally, it doesn't mention any prerequisites or limitations, leaving the agent without enough information to fully interpret the response or validate the call.

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 for parameter meaning. It mentions 'profile' and 'platform' but doesn't explain what values platform accepts (beyond the default 'tv') or what profile_id refers to (e.g., a user profile). The schema provides min/max and default, but the description fails to add semantic depth about the parameters' roles.

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 uses the specific verb 'Read' and identifies the resource as 'home screen layout/catalog configuration' for a profile on a platform. This clearly distinguishes it from the sibling nuvio_update_home_catalog_settings and other getter tools like nuvio_get_settings, which likely target different 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?

The description provides clear context that this is a read-only operation for catalog settings, which implies when to use it (when you need current catalog configuration). It doesn't explicitly state exclusions or name alternatives, but the sibling set makes the read/update distinction obvious. The guidance is adequate but not explicit about 'use this instead of X'.

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