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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is fully covered by structured data. The description adds nothing behavioral beyond that – no mention of pagination, filters, result shape, or scoping for a list-like GET endpoint.

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 first sentence is duplicated verbatim, wasting half the description, and the operation ID is low-value metadata for an agent. No useful information is front-loaded because there is effectively no content beyond the path.

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 GET endpoint with nested-object parameters, 0% schema coverage, and no output schema, the description should clarify at least what the templates are and what the query object can filter on. The only bridge offered is a reference to describe_operation, leaving the agent with gaps that must be resolved by calling another tool first.

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 (a free-form 'query' object and an empty 'params' object) are undocumented, so the description carries the full burden. It only says describe_operation provides native request schemas, which is a pointer for discovery but does not explain what keys the query object accepts or how they shape the response.

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 raw HTTP path repeated twice ('GET /api/notification-settings/templates'), which essentially restates the title and operation ID rather than stating what a notification settings template is or what the call returns. It does not distinguish this tool from siblings such as get_notifications_templates, get_notification_settings_f43b492a9011960665a90046, or get_notification_settings_preview_59e19ca6c60eef03384ccc16.

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 the many other notification-related sibling tools. The only actionable hint is that describe_operation provides native request schemas, which is a schema-discovery pointer rather than usage context, and no prerequisites or exclusions are stated.

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