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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds ordering (newest first), the content types included, and the limit default and ceiling, which is meaningful context beyond the structured fields. It stops short of describing pagination or what happens beyond the newest set.

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?

It is one front-loaded sentence covering purpose, ordering, return fields, and the one optional parameter. Every element earns its place; the parenthetical content list is slightly dense but not wasteful.

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?

With no output schema, the description usefully enumerates the returned fields, and with one optional parameter it covers the default and cap. For a simple read-only listing tool this is close to complete, missing only guidance on when to choose it over sibling tools.

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 0% and the schema itself only carries numeric bounds, so the description must compensate. It does so by supplying the default (10) and repeating the maximum (30), which the schema does not state as a default. The meaning of the single parameter is therefore clear.

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 and scope: newest updates on kipode.de, covering KI-Radar and topic-page updates. It also states the return shape (date, category, summary, link), so an agent knows what it gets without opening the schema. It doesn't explicitly contrast itself with siblings like suche or themen, which keeps it below a 5.

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; the agent must infer from the name and siblings that this lists recent items rather than performing keyword search (suche) or browsing categories (themen). Nothing tells the agent to prefer or avoid this tool in overlapping situations.

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