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

The annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds value by naming the fields returned (Kind, Thema, Bausteine, Fortschritt, Link), but it says nothing about ordering, pagination, or result size.

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 description is a single, front-loaded sentence with no wasted words. It efficiently covers the resource, scope, and returned fields.

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 simple two-parameter list tool with no output schema, the description usefully names the fields returned. However, it leaves the 'class_id' parameter ambiguous and provides no routing guidance relative to closely related sibling tools, so it is only adequate rather than complete.

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 coverage is only 50%: the 'class' parameter has a description, but 'class_id' is undocumented in both the schema and the description. The description mentions filtering by class but does not clarify the relationship between 'class' and 'class_id', so it does not compensate for the coverage 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 clearly states the resource (Lernpakete/Förderung) and scope (all packages or those of one class), so an agent knows what is being retrieved. It does not, however, distinguish this tool from related siblings like list_student_packages or get_support_progress, leaving the agent to infer the boundary.

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?

The phrase 'alle oder die einer Klasse' implies you can list everything or filter by class, which gives some usage context. But there is no explicit guidance on when to choose this tool over list_student_packages or get_support_progress, nor any exclusions or prerequisites.

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