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

The annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds meaningful behavioral context by stating it returns the parent shop and only a first page of live/upcoming and past/replay shows, which tells the agent about return scope and pagination limits.

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 that efficiently communicates the resource and its returned contents. There is no filler or redundancy.

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?

For a simple read-only detail tool with a fully described single parameter and an output schema, the description is largely complete because it explains the key returned content. It does not cover authentication, rate limits, or deeper pagination semantics, but those are secondary here.

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%, and the single id parameter is already fully documented in the schema, including its UUID format and likely source. The description adds no additional parameter syntax or constraints beyond what the schema provides, so the 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?

The description clearly identifies the resource as a Fanatics Live channel detail page and specifies it returns the parent shop plus a first page of live/upcoming and past/replay shows. It does not use an explicit retrieval verb and does not name sibling tools, but an agent can still distinguish this from show- or shop-specific tools by the channel-level scope.

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 explicit guidance on when to use this tool versus alternatives such as fanaticslive_show, fanaticslive_shop, or fanaticslive_shop_shows. The description implies it is for channel detail lookups, but it provides no usage conditions, prerequisites, or exclusions.

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