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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It implies a read-only informational lookup but says nothing about what data is returned, whether it is static content, or how it relates to the other service-related tools. For a zero-param info tool the gap is modest but real.

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, front-loaded sentence with no filler or repetition. It is efficiently sized, though arguably too thin to route an agent confidently.

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 zero parameters and no output schema, the description is the only source of information, and it gives just one sentence. It is minimally adequate for a simple static info tool but leaves the relationship to sibling tools and the nature of the returned content unspecified.

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?

The tool takes no parameters (parameter count 0), so there is nothing for the description to compensate for. Baseline of 4 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 states a specific resource – an overview of the services offered by a named provider (Roman Svoboda / RSolution.cz). This distinguishes it implicitly from siblings like cenik (pricing) and dostupnost (availability), though it never names them. The verb 'Přehled' (overview/list) is clear enough to convey intent.

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 explicit guidance on when to use this tool versus cenik, dostupnost, or napis_mi, nor any exclusions. Usage is only inferable from the fact that it lists services. An agent must guess whether to call this before or instead of the pricing/availability tools.

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