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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds genuinely useful behavioral context beyond that: it discloses the 403 failure mode when seller settings are missing and that the tool explains the error, which helps an agent interpret a failure.

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, front-loaded with the core function and followed by the failure condition. Efficient overall, though the odd leading indentation and the trailing 'this tool explains that' phrasing are slightly awkward.

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 single-parameter read with no output schema, the description covers both what is returned (price per condition grade) and the key gotcha (the 403 for accounts without seller settings). The main gap is that it never addresses the release_id input.

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 release_id parameter, its expected format, or what value to supply. With a required input entirely undocumented in both the schema and the description, semantics rest only on the self-explanatory parameter name.

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+resource: it returns suggested sale prices per condition grade sourced from Discogs sales history. The purpose is clear and unambiguous, though it does not differentiate itself from any sibling (no competing pricing tool exists in the list, so differentiation is less critical).

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 implied rather than stated: an agent can infer it should call this when it wants pricing for a specific release. There is no explicit 'when to use' vs. 'when not to use' guidance and no named alternative, so the guidance remains implicit.

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