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

Annotations already declare destructiveHint=true, so the description's job is to say what gets destroyed — and it does, naming the cascading loss of monitors and their results plus the cancellation of scheduled or in-progress maintenance. It stops short of permission requirements or confirmation behavior, which keeps it from a 5.

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 permanence and cascade front-loaded ahead of the secondary maintenance-cancellation effect.

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, two-parameter tool with an output schema and full parameter documentation, the description covers the main side effects an agent needs to warn about. Only auth/permission prerequisites and whether references elsewhere break are unaddressed.

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 both parameters (groupId, projectId) already document their sources (list_status_groups, list_projects) in the schema. The description adds nothing about parameter semantics, 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?

States a specific verb (permanently delete) and resource (status group), plus the cascade scope: monitors and their results go with it. That cascade detail alone separates it from update_status_group and the single-resource delete_status_check/delete_status_maintenance siblings.

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 or when-not-to-use guidance, and no pointer to alternatives such as update_status_group (if the group should be kept) or the individual delete_* tools. The word 'Permanently' hints at caution but the agent must infer when this tool is the right choice.

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