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

With no annotations, the description carries the full burden. It does disclose a privilege requirement ('Operators only') and that it removes a privilege level, but it says nothing about failure modes, whether the target must currently be a moderator, or what is returned.

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 short sentences with the action front-loaded and the audience constraint last. The '(#)' notation is slightly cryptic but the whole definition is free of filler.

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 privilege mutation with no annotations and no output schema, the description covers the action, the target, and the permission requirement. It stops short of explaining outcomes or error behavior, which leaves a modest gap.

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 50% — only 'channel' is described in the schema. The description clarifies 'nick' as the target user whose status is removed and implies the channel context via '(#)', but it does not fully compensate for the undocumented nick parameter.

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 uses a specific verb+resource: 'Take moderator (#) status from a nick', which distinguishes it from the operator-oriented sibling 'deop'. It does not explicitly name siblings, but the '#' qualifier signals it is the moderator (half-op) counterpart of a deop.

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' states a precondition, which is useful context. However there is no guidance on when to prefer this over deop or mod, nor when-not to use it, so usage is only implied by the verb.

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