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

With no annotations provided, the description carries the disclosure burden alone; 'aktueller Verfügbarkeitsstatus' implies a live, read-only lookup and defines the unfiltered default scope. However, it says nothing about data freshness, whether results are cached, or any auth/rate-limit behavior for a monitoring endpoint.

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 lines with no padding: the purpose leads, and the parameter note follows. Front-loading is good, though the bare two-block layout without a marker for the parameter line is slightly rough.

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-optional-parameter read tool with an output schema (which handles return-value documentation), the description covers purpose, filter semantics, and default behavior adequately. Gaps are limited to freshness/auth context, which is minor at this complexity.

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 0%, so the description must compensate, and it does: it explains that 'name' is an optional substring matched against service name or slug, supplies a concrete example, and states the default (all services when omitted). Only the matching case-sensitivity/partial-match rules remain unstated.

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 states a specific resource and scope: the current availability status of monitored services ('Aktueller Verfügbarkeitsstatus der überwachten Dienste'). An agent can tell this is a status-lookup tool, though it never explicitly contrasts itself with the siblings new_servers or recent_changes.

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 statement of when to reach for this tool versus the sibling tools, nor any prerequisites or exclusions. The only contextual hint ('Ohne Angabe: alle Dienste') is parameter behavior rather than usage guidance.

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