get--v3-domain-tag

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Get a tag' implies a read-only operation but doesn't specify permissions, rate limits, error conditions, or response format. It lacks details on what 'tag' refers to in this context (e.g., a label for a domain), making it insufficient for safe and effective use.

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 extremely concise with just three words, making it front-loaded and free of unnecessary details. However, this conciseness comes at the cost of clarity and completeness, but as a standalone assessment of brevity, it earns full marks for efficiency.

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?

Given the tool's complexity (2 required parameters), lack of annotations, 0% schema description coverage, and no output schema, the description is completely inadequate. It doesn't explain the tool's purpose, parameters, behavior, or output, leaving the agent with insufficient information to invoke it correctly in context with sibling 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?

The input schema has 2 parameters (domain and tag) with 0% description coverage, meaning they are entirely undocumented. The description 'Get a tag' adds no semantic information about these parameters—it doesn't explain what 'domain' and 'tag' represent, their expected formats, or how they relate to the operation, failing to compensate for the schema's lack of documentation.

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 'Get a tag' is a tautology that merely restates the tool name without adding meaningful context. While it indicates a retrieval action, it doesn't specify what kind of tag (e.g., email domain tag, metadata tag) or what resource it operates on, making it vague compared to sibling tools like 'get--v3-domain-tags' or 'get--v3-domain-tag-stats'.

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 description provides no guidance on when to use this tool versus alternatives. It doesn't mention any prerequisites, context, or distinctions from sibling tools such as 'get--v3-domain-tags' (which might list tags) or 'get--v3-domain-tag-stats' (which might provide statistics), leaving the agent with no usage direction.

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