Deleting the report subscription

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

Annotations already indicate destructiveHint=true, so the description's 'Removes' adds no new behavioral insight. Critically, it fails to disclose the required 'confirm' parameter and the safety net of 'dry_run', which are important behavioral details not captured by annotations.

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?

Extremely short but redundant: two sentences saying essentially the same thing. While concise, the repetition wastes an opportunity to provide useful information.

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 that it's a destructive action with a confirm parameter and dry_run option, the description is inadequate. It does not explain the confirmation step, the effect of dry_run, or what the output schema returns. The description leaves the agent uninformed about safe execution.

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 the schema describes each parameter well (confirm const 'YES', dry_run default true, subscription_id). The description adds no additional semantic value beyond the schema, so baseline 3 is appropriate.

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?

Description states 'Deleting the report subscription. Removes the report subscription.' which clearly indicates the action and resource. However, it does not differentiate from sibling delete tools like 'delete_report' or provide any unique purpose context beyond the name.

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 vs alternatives. Does not mention prerequisites, conditions, or that it should only be used when a subscription is no longer needed. Siblings exist but no contrast provided.

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