slack_kick_from_channel

DestructiveIdempotent

Removes a Slack member from a channel via the project-governed connector, with idempotency and approval support for controlled write actions.

Instructions

Slack connector operation kick_from_channel (platform tool slack.kick_from_channel).

Routes only through the exact project/account governed connector authority.

Args: arguments: JSON string of arguments for the connector operation. project_id: Authenticated Project UUID. project_ref: Exact project correlation reference. connector_account_ref: Project-bound connector account alias. idempotency_key: Stable business-action identity. effect: Claimed read or write effect; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

B3.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=false and destructiveHint=true. The description adds useful behavioral context by disclosing the governed routing constraint, explaining that `effect` is verified by Spring, and noting that `approval_ref` is needed when resuming a write. This goes beyond what the annotations provide and helps the agent understand the write-approval flow.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and organized, front-loading the tool identity and routing constraint before listing parameters. The initial sentence is slightly redundant with the tool name, but the overall structure is scannable and free of unnecessary filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Even with annotations and an output schema, the description is incomplete for correct invocation. It does not explain what `kick_from_channel` does at the Slack level, what fields the `arguments` JSON must contain, or how to obtain/provide the approval reference for writes. An agent would likely struggle to call this tool correctly without additional knowledge.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, but it only gives terse generic labels for wrapper fields. The critical `arguments` parameter is described merely as 'JSON string of arguments for the connector operation' with no indication of the Slack-specific payload needed (e.g., channel and user identifiers). The other parameters receive minimal definition but do not help construct a correct invocation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description identifies the tool as a Slack connector operation for `kick_from_channel`, which clearly names the action and resource. It does not restate the name as a tautology, but it also does not explain in natural language that this removes a member from a Slack channel. The purpose is reasonably clear from the name and platform-tool reference, though sibling differentiation is not explicitly addressed.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only usage-related statement is the routing constraint: 'Routes only through the exact project/account governed connector authority.' There is no guidance on when to use this tool versus alternatives like `slack_invite_to_channel`, `slack_join_channel`, or `slack_archive_channel`. The description gives no when/when-not context beyond a governance restriction.

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