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

Annotations already declare that this is a non-read-only, idempotent, non-destructive, closed-world operation. The description adds useful domain context about the created identity owning accepted contract families independently of employees, but it does not explain permissions, side effects, billing implications, or what is returned.

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 definition is a single front-loaded sentence with no redundant or wasted text. It states the action and the conceptual result 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?

For a simple three-parameter creation tool with rich annotations and full schema coverage, the description covers the core purpose. However, it omits when-to-use guidance, return-value expectations, and any operational caveats beyond what the annotations already state.

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 100%, so name, billing_email, and agent_key are already documented in the schema. The description adds no parameter-specific meaning beyond that structured documentation, so the baseline score of 3 applies.

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 gives a specific verb and resource: "Create an organization identity" that can "own accepted contract families independently of employees." This is clearer than a tautology, but it does not explicitly distinguish the tool from nearby procurement or agent-registration siblings.

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?

It provides no guidance on when to use this tool versus alternatives such as procurement_contract_assign, procurement_contract_run, or agent_register. There are no stated prerequisites or exclusions beyond the implied creation context.

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