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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is partly given. The description still earns credit for disclosing the cascade — that all emails created from the template are also removed — which is not in any structured field. It stops short of covering permission requirements or behavior when the name does not exist.

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, no waste, and the permanent/cascading nature is front-loaded before any implied caveats. Nothing could be cut without losing meaning.

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?

An output schema exists so return values need not be explained, and the destructive cascade is covered. Minor gap: it does not say whether deletion is scoped to the current organization or what an agent should expect if the template name is not found.

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 single 'Name' parameter is already documented with 'Name of the template to delete.' The description's 'by name' only reinforces that; it adds no format, casing, or lookup semantics beyond the schema.

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 ('Permanently delete a template') and adds the blast radius ('removes all emails created using this template'). That is enough for an agent to distinguish it from edit_template/get_template, though no sibling is named explicitly.

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?

The word 'Permanently' hints at the caution needed, but there is no explicit when-to-use guidance, no pointer to edit_template as the non-destructive alternative, and no statement about what to do if the name is wrong. Usage is implied rather than stated.

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