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 'No changes' simply repeats the structured safety profile. The description adds no behavioral context such as whether results are paginated, what a digest preference contains, or tenant scoping effects.

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 and front-loaded, but 'through the existing tenant application' is filler that consumes space without adding meaning, and the remaining sentence is redundant with annotations.

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 paginated list-style read tool with two undocumented parameters and no output schema, the description should at minimum explain paging and result shape. It covers neither, so an agent cannot call it confidently.

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 neither limit nor offset is documented anywhere. The description makes no attempt to explain paging semantics or defaults, leaving the agent to infer them from the schema's constraints alone.

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 names a verb (Read) and the resource (notification digest preferences), so the subject matter is identifiable. However, it largely restates the tool name and title without clarifying scope, and it does not distinguish this from close siblings like get_employee_notification_preferences or get_organization_notification_preferences.

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 the employee- and organization-level notification preference tools, nor any stated prerequisites or exclusions. An agent must guess which preference scope it needs.

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