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

With no annotations provided, the description carries full burden for behavioral disclosure. It states what data is returned ('Ort, Richtung und Details' - location, direction, and details) which is helpful, but doesn't mention important behavioral aspects like whether this is real-time or cached data, rate limits, authentication requirements, error conditions, or data freshness. For a public API tool with no annotation coverage, this represents significant gaps.

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 appropriately concise with three sentences that each serve a purpose: stating the tool's function, describing the returned data, and explaining the parameter. It's front-loaded with the core purpose. The only minor inefficiency is the separation of the parameter explanation into an 'Args:' section rather than integrating it more naturally.

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?

Given the tool's moderate complexity (retrieving dynamic construction data), no annotations, no output schema, and 0% schema description coverage, the description is minimally adequate. It covers the core purpose and parameter meaning but lacks important context about data format, freshness, limitations, and error handling. The absence of output schema means the description should ideally describe return values more thoroughly.

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 description adds meaningful context for the single parameter 'autobahn' by explaining it's the highway designation with concrete examples ('A1', 'A7', 'A61'). Since schema description coverage is 0% (the schema only shows title and type without explanation), and there's only one parameter, this compensation is effective. The description doesn't mention the default value 'A1' shown in the schema, but provides the essential semantic understanding.

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 specific action ('abrufen' - retrieve/fetch) and resource ('aktuelle Baustellen auf einer deutschen Autobahn' - current construction sites on a German highway). It distinguishes itself from siblings like 'autobahn_ladestationen' (charging stations) and 'autobahn_sperrungen' (closures) by focusing specifically on construction sites rather than other highway-related data.

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 description provides no guidance on when to use this tool versus alternatives. While it's clear this tool retrieves construction sites, there's no mention of when to use it versus 'autobahn_sperrungen' (which might include construction-related closures) or 'autobahn_warnungen' (which might include construction warnings). No prerequisites, exclusions, or complementary tools are mentioned.

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