marketplace_allowlist_user

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

With no annotations, the description carries full behavioral burden. It only mentions the owner restriction and optional permissions, omitting side effects, prerequisites, or consequences of allowlisting a user. The mutation side is implied but not disclosed.

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?

Single sentence, front-loaded, zero filler. Comprehensible at a glance, though more detail would be welcome elsewhere.

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?

Given the tool's moderate complexity (5 params, nested object, no output schema) and lack of annotations, the description is too sparse. It doesn't explain what allowlisting accomplishes, what 'special permissions' do, or how this fits into the broader marketplace access-control workflow.

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 is 3. The description's phrase 'optional special permissions' vaguely hints at the customRateLimit parameter but doesn't add concrete meaning beyond the schema's own descriptions.

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?

Description clearly states the action ('Add a user to the allowlist') and the resource, and notes the 'tool owner only' restriction. It distinguishes itself from block/unblock siblings, but doesn't elaborate on what 'special permissions' means, leaving some ambiguity about its exact scope.

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 explicit when-to-use guidance or alternatives are provided. The only hint is 'tool owner only', which restricts who can call it but doesn't explain under what circumstances to use it versus other access-management tools.

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