yd_metrika_label_create

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

With no annotations present, the description holds full responsibility for behavioral disclosure. It provides no information about side effects, permissions, limits, or what happens upon successful creation, leaving the agent completely in the dark.

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 (2 words) but at the expense of clarity and completeness. While front-loaded, it fails to convey necessary context, earning a middling score.

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?

Despite the tool's simplicity, the description is critically incomplete. It lacks any context about the label's purpose within Yandex Metrika, expected behavior, or relationship to other Metrika entities, making it insufficient for an agent to use correctly.

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 schema description coverage is 100%, so the baseline is 3. The tool description adds no additional meaning to the 'name' parameter beyond what the schema already provides.

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 'Create a label' is essentially a tautology, restating the tool name without adding specificity about what kind of label or its context. It does not distinguish this tool from sibling label operations like delete, update, or link.

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 usage guidelines are provided. The description does not specify when to use this tool versus other label-related tools, nor does it offer any conditions or alternatives.

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