slack_set_status

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

With no annotations, the description carries the behavioral disclosure burden. It reveals the core write effect and clear behavior, but does not mention overwriting an existing status, permission requirements, or how expiration interacts with clearing. This is adequate for a low-risk setter but not deeply informative.

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 carry the core action and the important clearing exception with zero fluff. The most relevant information is front-loaded.

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?

Combined with the detailed schema, an agent knows the required parameter, optional parameters, and the clear-status behavior. Missing output schema and annotation context leave a small gap, but this is minor for such a straightforward status-setting tool.

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 100% and every parameter already has a meaningful description (e.g., empty string to clear, omit to clear emoji). The description restates the empty-text clearing behavior but adds little beyond the schema, so the baseline 3 applies.

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 states a specific action ('Set your Slack status') with the resource and content type ('emoji + text') and even covers the clearing use case. It is unambiguous against the sibling tools, none of which perform status updates.

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?

'Use empty text to clear status' gives parameter-level usage guidance, but the description does not explain when to choose this tool over alternatives or when not to use it. The when-to-use case is only implied by the tool's purpose and name.

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