B3.4/5.0
Behavior3/5

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

With no annotations, the description carries the full burden, but it does disclose two useful behavioral facts: the data is 'live' (freshness) and comes from CITA (source/provenance). It does not state read-only nature explicitly, authentication needs, rate limits, or whether results are exhaustive.

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?

A single front-loaded sentence with no wasted words. The scope (Luxembourg motorways) and source (CITA) are packed efficiently without padding.

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

Completeness4/5

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

For a parameterless-required, read-only lookup with no output schema, the description adequately conveys what categories of events come back. Its only real gap is not routing the agent against the adjacent get_traffic sibling.

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

Parameters3/5

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

Schema description coverage is 100% and the single 'road' parameter is documented in the schema ('Optional road filter such as A4 or B40'). The description adds nothing about the filter, so the baseline 3 applies since the schema does all the work.

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

Purpose4/5

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

States a specific verb ('Get') and resource ('traffic events'), then enumerates the exact event types returned (roadworks, lane closures, incidents, equipment faults) and the scope (Luxembourg motorways). This distinguishes it from the sibling get_traffic in substance, but never names that sibling explicitly, so differentiation is left implicit.

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

Usage Guidelines2/5

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

There is no explicit when-to-use guidance and no named alternative. An agent must infer from the event-type list that this covers live disruptions rather than general traffic conditions, which is a meaningful ambiguity given get_traffic exists in the sibling set.

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