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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds genuine context beyond that: it characterizes the read as a status/inspection call and clarifies that enabling the connection is an out-of-band approval in the app, so this tool cannot perform the connection itself.

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: the first front-loads exactly what the status returns, and the second carries a single, non-redundant operational caveat. No filler, no repetition of the title.

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?

With no output schema, the description carries the burden of describing return content, and it does so by naming the three status areas. It stops short of describing the shape of the response (e.g., booleans vs lists per area), so it is complete at the conceptual level but not fully so.

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?

The tool takes zero parameters, so per the calibration the baseline is 4. There is nothing for the description to disambiguate, and it correctly does not invent parameter-like details.

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 names a specific verb+resource (Slack connection status) and enumerates the three things it reports: workspace connection, channel-to-notification rules, and teammate-to-Slack-user matching. It clearly distinguishes itself from generic siblings like get_setup_status by being Slack-specific, though it never explicitly contrasts itself with them.

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?

There is no explicit when-to-use or when-not guidance. The parenthetical that connecting Slack is an approval done in-app via settings_link implicitly routes the connect flow away from this tool, which is a useful hint, but the agent must infer when to call get_slack_status versus get_setup_status or get_notification_preferences.

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