remove_user_from_channel_via_name_or_id

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

With no annotations at all, the description does do real work by flagging the operation as destructive and disclosing a confirmation requirement — meaningful for a mutation tool. However, it omits permission requirements, reversibility (a removed user can presumably be re-added), and error behavior when the user is not a member; it also says "confirmation code" while the schema's `confirmationToken` is optional and only `confirm: true` is required, an ambiguity left unaddressed.

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 sentences, zero filler, with the destructive nature front-loaded immediately after the purpose. Every clause carries information an agent needs before invoking a delete-style operation.

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, four-parameter mutation with no annotations and no output schema, the description covers the safety headline but leaves gaps: it does not say whether the removal is reversible, what scope of permission the caller needs, or what the tool returns on success or failure. The rich schema compensates for the identifier parameters, so the definition is workable but thin on the destructive-operation context.

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 four parameters (including the MUST-ASK/DO-NOT-GUESS guidance) are fully documented in the schema; baseline is 3. The description adds only the loose nod that a confirmation token exists, which the schema already explains more precisely.

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?

Specific verb + resource ("Remove a user from a channel") that is unmistakable against the sibling `add_users_to_channel_via_name_or_id`. It stops short of the 5 bar because it never explicitly contrasts itself with siblings or clarifies that this removes membership rather than the user account itself.

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 / when-not-to-use guidance and no named alternatives. The only contextual cue is "requires confirmation code," which is a prerequisite, not usage guidance — an agent gets no help deciding between this and other channel-membership tools.

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