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

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only a pointer to describe_operation and does not mention authentication, return shape, or any behavior beyond what annotations already provide.

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 endpoint string is repeated verbatim twice, which is pure waste, and the operation ID is unlikely to help an agent select or invoke the tool. The relevant information is front-loaded but under-specified rather than concisely informative.

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?

This is a read-only by-id retrieval tool, so annotations handle safety, but the description never says what a notification rule is, what the response contains, or how the id is used. With no output schema and zero schema parameter descriptions, the description should carry more context than it does.

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 only required parameter is 'id'. The path template ':id' weakly signals that id is a path parameter, but the description does not explain what id identifies, nor does it mention the 'query' object parameter at all. With two parameters and no schema descriptions, this leaves meaningful gaps.

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 restates the HTTP endpoint 'GET /api/notifications/rules/:id', which does identify a specific verb and resource with an id. However, it is essentially a duplicate of the tool name/title and never states in plain language that this retrieves a single notification rule, nor how that differs from the sibling list tool get_notifications_rules.

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 tool instead of get_notifications_rules, get_notification_settings, or other notification-related siblings. The only directive is to use describe_operation for native request schemas, which is schema discovery, not usage context.

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