wb_tag_update

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only indicates a mutating update operation and lists fields, but does not describe side effects, failure behavior, idempotency, or whether the operation fully replaces existing tag data.

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 very short and front-loaded, immediately identifying the operation and affected fields. The Russian gloss is redundant but not harmful, and no unnecessary sentences are present.

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 no annotations, no output schema, and zero parameter coverage, the description is too thin to fully support correct invocation. It lacks guidance on the required identifier, expected value formats, response behavior, and how this update relates to tag lifecycle operations.

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 description coverage is 0%, so the description must compensate by explaining parameters. It mentions 'name' and 'color', but omits the required 'tag_id' parameter and provides no format or semantic details for the color value beyond the bare schema property names.

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 states a clear verb ('Update') and resource ('a tag'), and names the mutable fields ('name, color'). It does not explicitly differentiate from sibling tools like wb_tag_create or wb_tag_delete, but the verb alone makes the core purpose evident.

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?

There is no guidance about when to use this tool versus alternatives such as wb_tag_create or wb_tag_delete. The description does not mention prerequisites, whether all fields must be provided, or any conditions under which updating would be appropriate.

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