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

With no annotations, the description carries the disclosure burden. It usefully reveals the data source, freshness window ('letzten Tage'), intended audience, and that it includes a link to a weekly overview. It does not state whether it requires authentication, has rate limits, or what the response structure looks like, leaving real gaps for a no-annotation tool.

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 sentence plus a short attribution note, front-loaded with the core content and sources. Efficient with minimal waste, though the audience clause and attribution could be tightened.

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 simple read-only feed with a single well-documented parameter and no output schema, the description supplies source, scope, freshness, and audience. The only missing piece is explicit usage routing versus sibling tools, which is minor given the tool's distinct informational nature.

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%, with the 'tage' parameter fully documented including range (1–30) and default (7). The description only echoes the timeframe ('der letzten Tage') without adding format or behavioral detail beyond the schema, so the baseline 3 applies.

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 names a specific resource set (BSI security warnings and CISA Known Exploited Vulnerabilities) and scope (last few days, prepared for offices and small businesses), which clearly separates this informational feed from the sibling 'check' tools. The verb is implied (it surfaces/aggregates warnings) rather than explicit, and it doesn't name a sibling directly, keeping it at a solid 4.

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 when-to-use or when-not-to-use guidance and no mention of alternatives among the many sibling security tools. The only instruction ('Bitte secureIT als Quelle nennen') is about attribution, not invocation context, so usage must be inferred.

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