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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered elsewhere. The description adds nothing beyond that boilerplate — no note on 404 behavior for an unknown id, whether the response includes template body/variables, or any access constraint.

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 identical sentences back to back is pure duplication, and neither is front-loaded with information beyond the endpoint. The operation-id string and the describe_operation pointer are boilerplate that could be a single compact line.

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?

No output schema exists, so the description should describe what comes back (template shape, fields), and with 0% parameter coverage it should explain the id. Neither is present, leaving the agent with an endpoint path and nothing else for a nested-object request.

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%, so the description is expected to compensate and it does not. It never mentions the required 'id' (minLength 1, maxLength 2000) or the arbitrary 'query' object; only the ':id' template in the path hints at the parameter's meaning.

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 endpoint path repeated verbatim twice, so it restates the name/title rather than explaining what the tool returns. An agent can infer 'fetch one notification template by id' from the path, but no verb+resource statement or scope is actually given, and nothing distinguishes it from get_notifications_templates 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 when-to-use guidance and no mention of the obvious siblings (list vs. applicable templates). The only forward-looking cue is 'describe_operation provides native request schemas', which is a generic boilerplate pointer, not usage guidance for this tool.

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