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

With no annotations, the description carries the full burden, and it discloses almost nothing behavioral. The word 'Free' hints at an access/tier model across the server, which is a useful — if cryptic — trait beyond the schema, but it says nothing about ordering, pagination, rate limits, or response shape for a list operation.

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 short sentence with the scope statement front-loaded, which is appropriate for a no-arg list tool. The leading 'Free:' token is odd filler that spends words on pricing rather than behavior, slightly diluting an otherwise tight sentence.

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 zero-parameter list tool with no output schema and no annotations, the description is minimally adequate: it tells the agent what is returned (elections with date and status). It omits ordering, whether the result is complete/paginated, and how to drill into a specific election, leaving avoidable gaps.

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?

The tool takes zero parameters, so per the baseline there is no parameter semantics to explain; the schema is trivially complete at 100% coverage. The description cannot add or subtract parameter meaning here.

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 says the tool covers 'all German elections ... with date and status,' which conveys scope and return fields, but never states a verb — the listing action is only implied by the tool name. The sibling set contains many list_* and get_election* tools, and nothing here distinguishes this one beyond the word 'German.' It is more marketing copy ('Free:') than a specific verb+resource statement.

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 indication of when to use this versus get_election, get_election_statistics, or the other list_* siblings. No prerequisites or exclusions are given. The only implicit signal is that it returns everything, but the agent must infer that from scattered context.

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