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

Annotations already establish readOnlyHint and openWorldHint, so the safety profile is covered. The only added behavioral detail is 'paginated', which is already implied by the page and per_page parameters in the schema, leaving the description with essentially no value beyond structured fields.

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 fragment with no wasted words. It is terse to the point of being thin, but it is structurally clean.

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?

With a rich schema, annotations, and an output schema, the description only needs to orient the agent toward when and how to use the tool. It covers the what but omits sibling differentiation and any usage context, leaving a clear gap for an agent choosing among the many discogs_* tools.

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 100%, and the schema documents the label id, page numbering, and per_page limits. The description adds no syntax, default, or usage detail beyond what the schema already provides, so the baseline of 3 is appropriate.

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 names the resource ('Discogs label catalog') and indicates pagination, which is enough to infer that it lists releases tied to a label. However, it lacks a clear action verb and offers no differentiation from closely named siblings such as discogs_artist_releases or discogs_label.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives. An agent cannot tell from the description alone whether to reach for this tool or for discogs_label when it has a label id.

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