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

With no annotations, the description carries the full behavioral burden. It does disclose two genuinely useful behavioral facts: a permission restriction ('Operators only') and an immunity rule ('the founder stays an operator'). However, it does not say what happens if the nick is not an operator, whether the call is idempotent, whether the change is announced, or how failures are reported.

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 compact sentences with no padding, and the core action is front-loaded before the restrictions. The terse pidgin phrasing ('from a nick') is slightly awkward but not wasteful.

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?

This is a privileged mutation tool with no annotations, no output schema, and a half-documented parameter set. The description covers the action and one immunity rule but omits caller permission semantics, failure behavior, and the meaning of the channel parameter, which is not enough for an agent 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 description coverage is only 50%: 'channel' is documented in the schema, but 'nick' has no schema description. The description only restates that a nick is the target ('from a nick') and adds nothing about whether the nick must be present in the channel, whether channel defaults when omitted, or how an unknown nick is handled.

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 gives a specific verb and resource: 'Take operator status from a nick' clearly means removing op privileges from a user. It is clear on its own, but it does not differentiate itself from the inverse sibling 'op' or from 'demod', so an agent must infer the distinction from the short names.

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' hints at a prerequisite, but it is ambiguous whether that constrains the caller (must be an operator to invoke) or the target (nick must currently be an operator). No alternatives are named - nothing says to use 'op' to grant status or 'demod' for a different class of privilege - so the agent gets no routing guidance.

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