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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the safety profile is covered, but the description adds nothing beyond that: no mention of what uniquely identifies a template, what happens on duplicate alias, or what is returned. For a write operation the description should carry more.

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?

The single short sentence is front-loaded and free of padding, but here brevity reflects under-specification rather than discipline. Nothing is wasted, yet almost nothing is delivered.

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?

With a nested required object at 0% schema coverage, no output schema, and a sibling that reads templates back, the definition is insufficient: the agent cannot determine required field meanings or the expected response. Annotations cover the mutation flag but not the payload contract.

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 0% and the single top-level "body" param wraps six nested fields (type, alias, content, version, email_num, allow_smoothing), four of which are required. The description explains none of them — most critically the distinction between alias, content, and email_num — so an agent must guess at required payload semantics.

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 concrete verb and resource ("Create a writing template"), so the agent knows this is a creation operation on templates. However, "writing template" is left undefined and there is no differentiation from the siblings list_templates, update_template, and delete_template beyond the verb itself.

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 delete_template, nor any prerequisite or context about what a template is used for in this system. The create-verb implies the basic lifecycle position, but nothing in the text states it.

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