conversations_external_invite_permissions_set

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

No annotations provided, so description carries full burden. Only states it 'sets' permissions without disclosing behavioral traits such as whether changes are immediate, if it requires admin rights, or what the action parameter does. Lacks crucial transparency.

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?

Single sentence of 9 words is concise, but at the cost of missing essential details. While not verbose, it is too sparse to be fully helpful. Every word is functional, but the description overall is insufficient.

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?

Given the tool has 2 required parameters and many sibling tools, the description is inadequate. It does not explain parameter values, output schema (even though it exists), or when to use this tool. Extremely incomplete.

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 has 0% description coverage, and the description adds no meaning beyond parameter names. Channel and action are unexplained; no enum values, formats, or examples provided. The description fails to compensate for the schema 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?

Clearly states the tool sets external invite permissions for a Slack Connect channel. Verb 'set' and resource 'external invite permissions' are specific, and the tool is distinct from siblings like conversations_invite_shared or conversations_approve_shared_invite.

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 guidance on when to use this tool versus alternatives. Does not mention prerequisites, required scopes, or context where this tool is appropriate compared to sibling tools like conversations_invite_shared.

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