Label releases

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

With no annotations, the description carries full burden. It discloses sorting order (newest first), inclusion of artist, and pagination method (cursor). It does not mention error handling, rate limits, or idempotency, but these are common for read-only endpoints.

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 concise sentence that efficiently communicates the core functionality and key behaviors. No unnecessary words.

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 no output schema, the description adequately conveys what the tool does, but it does not specify the output structure. For a simple list endpoint, this is acceptable, but additional details on the response format would improve completeness.

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 only 33% (only 'label_id' has description). The tool description adds no parameter-level detail beyond the schema, leaving 'limit' and 'cursor' unexplained. This is a gap given the low schema coverage.

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 lists a label's releases sorted newest first, including the artist per release, and specifies cursor pagination. This distinguishes it from siblings like 'get_artist_releases' which focuses on a specific artist.

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 implied usage context (label releases, newest first) but does not explicitly state when to use this tool versus alternatives like 'get_artist_releases' or 'search_releases'. However, the purpose is clear enough for an experienced user.

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