Api privacy data transfers retrieve

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description still adds meaningful behavioral context that annotations cannot convey: the response is field-masked according to the caller's authorization. It stops short of explaining what happens on not-found or fully unauthorized access, which is why this is a 4 rather than a 5.

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 short sentence with no filler, and the most important behavioral fact (masking) is stated immediately. It is arguably too terse rather than too long; nothing in it is redundant.

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?

There is no output schema, no parameter description, and the description does not say which object type is returned, what fields exist, or how masking manifests in the payload. For a retrieve-by-id endpoint competing with several near-identical siblings, more context is needed to call it correctly and interpret the result.

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?

There is one required parameter, 'id' (a string), and the schema description coverage is 0%, so neither the schema nor the description explains its format. The description at least implies a single-record lookup keyed by an identifier, which is consistent with the required id field. No added syntax, format, or constraint guidance is provided, so the minimum-viable 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 says it returns 'a single object' but never names the resource (a privacy data transfer), so the reader must rely on the tool name to know what is being fetched. The added detail about unauthorized related fields being masked is genuinely informative, but the core 'retrieve a single data transfer by id' statement is only implied. It also does not distinguish this from the sibling 'privacy_data_transfers_object_retrieve'.

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?

No indication of when to use this versus 'privacy_data_transfers_list', 'privacy_data_transfers_object_retrieve', or 'privacy_data_transfers_cascade_info_retrieve', all of which are plausible alternatives in the sibling list. There is no mention of prerequisites such as needing the record id or of what happens when the caller lacks permission to view certain fields.

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