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

Annotations already declare readOnlyHint=true and openWorldHint=false, covering the safety profile. The description adds the observation cadence and the kind of changes captured, which is useful operational context, but it does not discuss filtering defaults, pagination, or return volume.

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?

Two sentences, reasonably front-loaded around the dataset contents. The final chronicle/news line is somewhat promotional but still signals positioning, so it is not wasteful enough to penalize heavily.

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 one-parameter read-only tool, the description covers what content comes back—visit descriptions, changes, prices, radar links—despite no output schema. It leaves out the default behavior when no place id is supplied, so it is not fully 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 100%, so the optional place id is already documented. The description does not explain the place id format or what happens when it is omitted, so it adds little beyond the schema.

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 paints a specific dataset: weekly observations of named Hamburg-area places with visible changes, prices, and radar links, so the agent can tell what get_places returns. It does not use an explicit retrieval verb or name a sibling alternative, but the resource scope is clear.

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?

No explicit when-to-use or when-not-to-use guidance is given, and no sibling tools are named. The closing line implies a use case—slow first-hand chronicle rather than news—but the agent must infer that this is the right tool over get_prices, get_radars, or get_history.

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