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

No annotations are provided, so the description carries full behavioral burden. It discloses that this is a mutation ('lift a ban') and that it is restricted to operators, but it does not explain side effects, idempotency, what happens if no ban exists, error behavior, or the response format.

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 description is two short sentences, front-loaded with the core action and followed by the key permission constraint. There is no wasted wording, and the structure is easy to parse quickly.

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 two-parameter moderation tool with no output schema, the description provides the essential action and permission requirement. However, it leaves notable gaps around parameter semantics (especially nick format) and behavioral details like error handling, which an agent would need to invoke 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 coverage is only 50%: the channel parameter has a brief description, while the nick parameter is undocumented. The description adds no meaning to either parameter, leaving the format and purpose of 'nick' unclear and failing to compensate for the coverage gap.

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 verb and resource with 'Lift a ban,' which is clear and distinguishable from the sibling 'ban' tool by its inverse action. However, it does not explicitly name or differentiate from siblings, keeping it from a 5.

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?

'Operators only' provides a clear permission constraint that implies who should use it, but there is no guidance on when to use it versus alternatives, no prerequisites beyond operator status, and no exclusions or context about when not to use it.

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