List Serato crates

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

Annotations already declare readOnlyHint, destructiveHint, and idempotentHint, so the safety profile is covered. The description adds value beyond these by revealing the exact output content (display path and distinct track count) and the filtering rule (exclusion of smart crates and internal spaces). It does not contradict annotations and gives concrete behavioral expectations.

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?

Two sentences, no filler. The core function and output detail are front-loaded, followed by the scope exclusion. Every clause contributes meaning; there is no 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 paginated list tool, the description covers the key aspects: what is returned, what is excluded, and the space it operates in. Pagination behavior is not described, but the output schema exists and the limit/cursor parameters are enough for a capable agent to infer. The description is adequate, though a brief note on pagination would have made it fully self-sufficient.

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 meanings. It does not mention `limit` or `cursor` at all, nor does it explain that the tool is paginated. An agent would have to infer pagination behavior from the schema alone, which is a substantial gap given the tool's listing purpose.

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?

States a specific verb ('List'), a precise resource ('crates in the Serato Library space'), and the output detail (display path and track count). It also distinguishes itself from siblings by explicitly excluding smart crates and internal spaces, so an agent can differentiate it from get_crate_tracks or audit_library without opening their schemas.

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 clarifies what is and isn't included ('Only crates in that space... excluded'), which is useful context. However, it never explicitly states when to prefer this tool over the sibling tools (e.g., 'use get_crate_tracks to inspect tracks within a crate'). Usage timing is implied by the resource named but not contrasted with alternatives.

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