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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe-read profile is covered. The description adds only that a single record is returned, and says nothing about data freshness, auth, or rate limits; with annotations carrying the burden this is a modest but adequate contribution.

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?

A single, front-loaded sentence with no wasted words. It is efficient, though its brevity borders on under-specification rather than maximal information density.

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 low-complexity, one-parameter lookup with 100% schema coverage, an output schema present, and safety annotations, the description is sufficient to call the tool. It nonetheless omits any routing context relative to the search/facets siblings, leaving a small gap.

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 coverage is 100% and the sole product_id parameter is fully documented in the schema (including an example id format). The description merely restates product_id, adding no syntax or format detail beyond what the schema already provides, so the baseline 3 applies.

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 (retrieves) and resource (PlayStation games dataset record) scoped to a single item via product_id. It is clear this is a single-record lookup rather than a search/list, though it does not name its siblings (datasets_playstation_games_search, datasets_playstation_games_facets) to disambiguate explicitly.

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 phrase 'record by product_id' implies usage (call it when you already have a product id), but there is no explicit when-to-use guidance and no mention of the search/facets alternatives. Usage must be inferred from the tool name and schema.

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