Motorways around Hamburg: jams, closures, roadworks

get_roads
Read-only

Current traffic jams (with delay in minutes), closures and roadworks on the motorways around Hamburg (A1, A7 incl. Elbtunnel, A23, A24, A25, A26, A39, A253, A255, A261) from the official Autobahn GmbH open data, refreshed every 10 minutes. Use it to answer questions like 'Is there a jam at the Elbtunnel right now?'. City roads such as Köhlbrandbrücke are not included.

A4.7/5.0
Behavior5/5

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

Adds substantial context beyond the readOnly/openWorld annotations: official Autobahn GmbH source, 10-minute refresh cadence, delay in minutes, and the exact road coverage. The exclusion note also prevents misuse for city roads.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads what the tool returns and its scope, then adds source/freshness and an example. Two sentences plus a short exclusion note, with no wasted text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter read-only query with no output schema, the description is complete: it covers content, source, refresh interval, supported roads, example use, and exclusions. Nothing essential for correct invocation is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the 'road' parameter is already documented. The description still adds useful semantics by listing the supported motorways (A1, A7 incl. Elbtunnel, etc.), which clarifies valid values beyond the schema's 'e.g. A7'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific resource and verb-like operation: current traffic jams, closures, and roadworks on motorways around Hamburg. It names the exact motorway set and explicitly excludes city roads such as Köhlbrandbrücke, so an agent can distinguish this from unrelated sibling tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a clear usage example ('Is there a jam at the Elbtunnel right now?') and explicitly excludes city roads. It does not name a sibling alternative for bridges or city roads, but the when-to-use condition is clear.

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