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

No annotations are provided, so the description carries the full burden. It conveys one behavioral fact — the identity owns contract families separately from employees — but says nothing about permissions, what the agent_key must be, whether creation is irreversible, or what happens on duplicate names. For a creation mutation with zero annotation coverage, this is a substantial gap.

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?

A single well-formed sentence with no filler and the core purpose front-loaded. It is efficient, though slightly abstract in phrasing.

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?

As a mutating creation tool with no annotations and no output schema, the description should say more about side effects, required agent authentication, and the resulting identity's lifecycle. It explains ownership semantics but is not complete enough for an agent to call it confidently.

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 the schema already documents name, billing_email, and agent_key. The description adds no parameter-level detail (e.g., format of agent_key or billing_email semantics), leaving the baseline 3 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?

States a specific verb (create) and resource (organization identity / procurement account), and explains its distinguishing scope: it owns accepted contract families independently of employees. This differentiates it somewhat from the procurement_contract_* siblings, though the connection to them is implied rather than named.

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 explicit when-to-use guidance, no prerequisites, and no named alternative among the many procurement_* siblings. The phrase 'independently of employees' hints at the intended scenario but the agent must infer when a procurement account is needed versus assigning or running a contract.

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