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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the parenthetical 'schreibt nie' largely restates structured data. It does add one genuinely new fact — that only the text of an approved ('freigegebenen') file is returned, implying a visibility restriction — but nothing about missing-file behavior or return shape.

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?

Two short sentences, front-loaded with the action and resolution method. The read-only parenthetical partly duplicates the annotations, which is slight waste but keeps the safety framing visible.

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 one-parameter read tool with full annotation coverage and no output schema, the definition covers what the tool does, how the target is identified, and that text is returned from approved files only. Missing only edge-case behavior for unknown names.

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 description coverage is 100% and the single 'name' parameter already documents alias examples, so the description's own example list ('kosten', 'faq', 'zuschuss.md') is redundant. Baseline 3 applies since the schema carries the parameter burden.

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?

States a specific verb+resource ('Liest eine Datei des Hubs') plus the resolution mechanism ('per Name oder Alias') with concrete alias examples. It does not name or rule out the sibling tools list_content/search_content, 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.

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

The lookup-by-name/alias framing implies the use case (fetch one known file), but there is no explicit guidance on when to prefer this over search_content or list_content, nor any stated prerequisite such as the file having to be approved.

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