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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds the meaningful behavioral trait that the default (no confirm) is a non-destructive preview rather than a partial delete, which is the most likely failure mode for an agent. It does not say whether the deletion is permanent or recoverable.

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, zero filler, with the destructive action stated first and the safety condition second. Nothing could be removed without losing 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?

For a two-parameter destructive tool with no output schema, the definition covers the essential mechanics: what it removes and the confirmation gate. It omits whether the operation is reversible or permission-restricted, which is the one remaining gap for a destructive call.

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 50%: confirm is fully documented in the schema, and the description merely restates it in shorter form. viewId has no description in either place; the phrase 'one of the user's saved views' hints at its role but supplies no ID format or source. Baseline 3 for partial coverage with the schema doing most of the work.

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 and resource ('Deletes one of the user's saved views'), which is unambiguous against the many sibling delete_* tools since the resource differs. It does not explicitly differentiate itself from siblings like delete_board or delete_list, but the resource naming carries that work.

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?

Gives a concrete invocation condition: confirm: true is needed or the call degrades to a preview. That is a genuine how-to-use rule rather than a when-to-use rule, and no alternative tool or exclusion is named, so it falls short of a 5.

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