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

Read-only and destructive hints are already provided by annotations, so the description only needs to add context. It proactively mentions the required permission and the fact that this is a create operation, which is useful behavioral information.

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 two short sentences with no redundant or filler content. It front-loads the primary purpose and then provides key usage details efficiently.

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?

The description is adequate for the simple create operation and covers permission and key parameters. It does not describe return values, but no output schema is present and this is not essential for deciding when or how to call the tool.

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?

Every parameter has a schema description, and the tool description adds practical meaning: name is required for creation, sort_order is optional and controls display order, and action is fixed to 'create'. This clarifies how to actually invoke the tool.

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 tool creates a workspace tag, using a specific verb and resource. This distinguishes it from tag-read and other write tools for different resources.

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 specifies required inputs (name) and the required permission (tag-management). It does not explicitly differentiate from tag-read, but the create action and resource make the primary use case clear.

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