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

No annotations are provided, so the description must disclose behavioral traits. It only says 'create,' which conveys mutation but does not explain side effects, permissions, idempotency, or response behavior. This is insufficient for a write operation without annotation support.

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, clear sentence that is front-loaded with the action and object. Every word contributes meaning, with no redundant or extraneous content.

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 tool with one parameter and no output schema, the description plus schema adequately cover the core purpose and input. The onboarding context adds situational completeness. It does not explain return values or side effects, but the low complexity mitigates the gap.

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 has 100% coverage for the single parameter 'name' with the description 'Agency or business name.' The tool description adds no additional semantic nuance beyond the schema, so the baseline of 3 is appropriate.

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 'Create a new agency/workspace during onboarding,' which uses a specific verb and resource. It clearly distinguishes from sibling tools like create_site or create_collection by focusing on 'agency/workspace' and specifying the onboarding context.

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 phrase 'during onboarding' implies when this tool is appropriate, but there is no explicit mention of when not to use it or alternatives. Unlike the high-calibration example, it does not name a sibling tool for alternative cases, so guidance is only implied.

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