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

No annotations are supplied, so the description carries the full behavioral burden for a destructive operation, and it discloses almost nothing. It does not say whether deletion is permanent/irreversible, whether templates in use by generated documents are protected, what permissions are required, or what the response contains on success or failure.

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?

One short sentence with the resource and key front-loaded and no filler. There is no wasted wording, though the terseness comes at the cost of the behavioral detail noted above rather than being a model of efficient completeness.

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?

The tool is structurally simple (one required string), which lowers the bar, but it is a destructive, irreversible-class operation with zero annotations and no output schema. An agent needs to know about permanence, permission requirements, and failure modes before invoking it, and none of that is present.

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 description coverage is 100% and the single slug parameter is documented in the schema itself as "The template slug to delete." The description's "by its slug" restates rather than extends that, so the baseline of 3 applies — no format examples (e.g., where to find the slug) are added.

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?

"Delete a template by its slug" gives a specific verb (delete) and resource (template) plus the identifying key. It's clearly distinguishable from siblings like create_template, update_template, and get_template via the verb, though the description itself doesn't explicitly name or route to those alternatives.

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 guidance on when to use this versus update_template or get_template, no prerequisites, and no note about what happens if the slug doesn't exist. The agent must infer that this is the removal path purely from the verb.

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