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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and a closed world, so safety is covered. The description adds nothing beyond that: no mention of return shape, pagination, filtering, or what a 'template' contains.

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?

It is short, but the first sentence is duplicated verbatim, which is pure waste. The only substantive content (operation ID and the describe_operation pointer) is boilerplate rather than front-loaded 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?

For a two-parameter list endpoint with no output schema and no described parameters, the description should explain what is returned and how to filter. Instead it supplies only an operation ID and a pointer to another tool, leaving the agent unable to call it meaningfully without a second lookup.

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 both parameters ('query' and 'params') are untyped open objects. The description does not explain either one; it only redirects to describe_operation for the native request schema, which is minimal compensation for a total documentation gap.

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?

The description is the HTTP endpoint repeated verbatim twice ('GET /api/notifications/templates. GET /api/notifications/templates.'), which essentially restates the tool name and title. An agent can infer it lists notification templates, but nothing distinguishes it from close siblings such as get_notifications_templates_by_id or get_notifications_templates_applicable.

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 statement of when to use this versus the several sibling template-listing tools. The only actionable sentence points to describe_operation for request schemas, which is a schema-discovery hint rather than selection guidance.

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