get_group_children

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

No annotations are provided, so the description carries full burden. It states it lists tracks, implying a read-only operation. No destructive or side effects are mentioned, which is accurate. However, it does not disclose any limitations, such as whether nested groups are included or if there is a maximum number of children returned. The description is basic but not misleading.

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 extraneous words. It efficiently conveys the core purpose. However, it could be slightly more informative (e.g., mention that it returns track details) without significant bloat, so it does not achieve a perfect 5.

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?

Given the presence of an output schema (not shown), the description need not detail return values. However, it does not address nesting depth (direct vs. recursive children) or special cases like empty groups. For a simple list tool, this is adequate but leaves some ambiguity.

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% – the schema provides no description for the 'group_index' parameter. The tool description does not explain what 'group_index' means, how to obtain it, or what valid values are. The parameter name is somewhat self-explanatory, but the description fails to add meaningful guidance beyond the schema.

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 'List all tracks that belong to a group track' clearly states the action (list) and the resource (tracks belonging to a group). It distinguishes from sibling tools like 'get_group' (which likely returns group properties) and 'list_tracks' (which returns all tracks). The verb-resource pair is specific and unambiguous.

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 implies usage when one needs children of a specific group, but it does not provide explicit when-to-use or when-not-to-use guidance. For example, it does not mention that to list all tracks one should use 'list_tracks' instead. No exclusions or alternatives are stated.

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