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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, non-open-world), so the description's added value is the ordering guarantee ('newest first') and the shape of each returned row. It adds real behavioral context beyond the annotations, though it says nothing about result volume, truncation, or default page size.

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?

One sentence, front-loaded with the verb and resource, with the return fields and ordering packed in without a wasted clause. Nothing to trim.

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 read-only listing tool with annotations covering safety and no output schema, the description usefully enumerates returned fields and ordering, which substitutes for the missing output schema. It is only incomplete on the 'limit' parameter's default and behavior when more than 25 sets exist.

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% and the description never mentions the single 'limit' parameter, its default, or the cap of 25. The parameter name and min/max bounds are self-explanatory in the schema, so this is a minor but real gap rather than a fatal one.

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?

Specific verb ('List') plus a bounded resource ('the DJ sets this account scanned on CrateWire') with the returned fields enumerated (title, source, date, status, tracks identified) and an explicit sort order. It does not name or contrast itself with any sibling (e.g. get_set_tracklist), so it falls short of the 5 bar.

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?

Usage is only implied: the 'this account scanned' phrasing scopes it to the caller's own sets, but there is no explicit when-to-use statement, no prerequisites, and no routing to alternatives such as get_set_tracklist or get_my_feed. Adequate but inferential.

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