Create User

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

With no annotations, the description carries the burden of behavioral disclosure. It adds one useful behavioral detail ('Disabled in read-only mode') and clearly implies a mutating operation via 'Grant', but it does not disclose permissions required, side effects, idempotency, or whether existing user access is replaced or appended.

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?

Two sentences, no filler, and the primary purpose is stated first. The read-only constraint earns its place as a compact but important behavioral warning.

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 schema covers parameters and an output schema exists, so structural invocation details are largely complete. Still, the description omits authorization context, side-effect details, and usage routing relative to similar sibling tools, leaving the definition minimally viable but not thorough.

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 baseline applies; both parameters are already described in the schema. The description adds no parameter-specific meaning beyond the schema's own documentation, but it does reinforce the roles of developer_id and user as the target account and the granted user.

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 specific action ('Grant a user access') and a specific resource ('a developer account'), making the tool's core purpose clear. It is implicitly distinguishable from sibling tools like list_users or create_grant, though it does not explicitly differentiate itself from similar grant-related operations.

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 'Disabled in read-only mode' line provides an explicit when-not condition, which is useful for tool selection in read-only contexts. However, the description gives no guidance on when to prefer this tool over related siblings such as create_grant or update_user.

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