make_admin_user

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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the safety profile is covered. The description adds genuine context about the blast radius ('full access to all settings and resources across the account'), but says nothing about reversibility, permission requirements, or side effects on existing sessions.

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 first two sentences say the same thing twice ('Grant user admin privileges' / 'Grant a user admin privileges using its unique identifier'), which is pure repetition. The third sentence about admin scope is the only genuinely additive one.

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 destructive, non-idempotent privilege-escalation mutation with no output schema, the description conveys the effect but omits failure modes, reversibility, and whether repeated calls are meaningful. Annotations carry part of that burden, but gaps remain.

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 reported as 0% for a single nested userId parameter, so the description's phrase 'using its unique identifier' does add some meaning. However, it adds no format, type, or lookup guidance beyond that, so it only partially compensates.

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+resource (grant admin privileges to a user) with a clear scope of impact. The grant/revoke pairing with the sibling remove_admin_user is inferable from the verb, though the sibling is never named explicitly.

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?

No when-to-use guidance, no prerequisites (e.g. the user must already exist), and no mention of the counterpart tool remove_admin_user for reversing the change. Usage must be inferred entirely from the verb.

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