get_group_info

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

As a read-only getter, the description implies no side effects, but with no annotations it doesn't explicitly disclose that or mention error behavior for invalid track indices. It focuses on return values, which is useful but leaves some ambiguity for edge cases.

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 compact and front-loaded with the core purpose, followed by a clear list of return values and an Args section. Every sentence provides needed information without waste.

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 one-parameter getter with an output schema, the description covers the essential return data and parameter semantics. It doesn't address potential errors or prerequisites, but for this straightforward tool, it's sufficiently complete.

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?

With 0% schema description coverage, the description compensates by explaining the only parameter: 'track_index: Zero-based index of the track.' This adds critical semantic meaning (zero-based) that the schema lacks, though it's brief.

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 states the tool's function: 'Get group and fold information for a track.' It enumerates specific outputs (foldable, group membership, fold state, group track name), distinguishing it from sibling tools like get_track_info or fold_track.

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 context implies this tool is for retrieving group/fold status of a track, but it doesn't explicitly state when to use it over alternatives like get_track_info. No exclusions or alternative tool mentions are provided.

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