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

Annotations already declare readOnlyHint=true and destructiveHint=false, covering the safety profile. The description adds minimal context ('attributes values', 'on your account') but does not disclose response format, error behavior, or authentication requirements beyond what annotations suggest.

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 sentence that front-loads the action. Though it slightly rephrases the title after the dash, it does add 'attributes values' and 'on your account,' so it is efficient without significant waste.

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 simple retrieve-by-ID operation with strong annotations, the description is adequate as a minimal viable entry. However, it lacks context about what 'attributes values' entail, typical response structure, or how it fits with other tag-related operations, so it is not fully complete.

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 0%, and the description only mentions 'by id,' leaving tagId mapping implicit. The required x-request-id (a UUID) and optional x-trace-id are completely unexplained, failing to compensate for the lack of schema descriptions.

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 clearly states the action ('Get specific tag by id') and resource ('tag'), with the added context of retrieving attribute values. This distinguishes it from sibling tools like retrieveTagList and retrieveTagAuditsList by targeting a single tag by ID.

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: it should be used when a specific tag ID is known. However, there is no explicit guidance on when not to use it or how it differs from the many other retrieve tools in the sibling list.

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