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

No annotations are provided, so the description carries the full burden, and it discloses only that the tool returns explanations. For a low-risk read-only lookup this is acceptable, but it omits any mention of output format (prose vs structured) or depth of explanation.

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?

A single front-loaded sentence with no wasted words, appropriately sized for a simple one-parameter lookup tool.

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 retrieval tool with a fully documented enum parameter and no output schema, the description is minimally adequate. It stops short of clarifying how results are returned or how it relates to the overlapping 'ask_swedish' sibling.

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 100% and the 'topic' parameter is fully enumerated with six values, so the schema does the heavy lifting. The description adds no meaning beyond what the schema already documents, which is the baseline expectation.

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 states a specific verb ('Get explanations') and resource ('Swedish grammar rules and patterns'), making the tool's function clear. It does not, however, differentiate itself from the sibling 'ask_swedish', which could plausibly answer grammar questions too.

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 versus alternatives like ask_swedish or practice_exercise. No conditions, prerequisites, or exclusions are given, leaving the agent to infer routing from the name alone.

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