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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=true, so the safety profile is fully covered. The description adds that the hub forwards the question to the module's own server, which corroborates the open-world behavior but is largely consistent with what annotations already convey; it says nothing about the shape or size of the response.

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 plus a bracketed provenance note, front-loaded with the purpose ('what the database contains and how to cite it') before the itemized scope. No filler.

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 zero-parameter informational tool with no output schema, the description is nearly complete: it tells the agent exactly which facts to expect back (counts, types, price-verification start date, license, citation). A brief note on response format would have closed the remaining gap.

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, so the baseline is 4. The description correctly implies a no-argument informational call and does not waste space on parameters that do not exist.

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 concrete resource (the culture database in Moja Serowarnia) and a concrete scope: what it contains and how to cite it, then enumerates the contents (number of cultures and shops, types, price-verification dates, license). That is far more specific than the title alone, though it never explicitly distinguishes itself from lookup siblings such as serowarnia_szukaj_kultur or from the analogous pasze_o_bazie.

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?

Usage is only implied by the enumerated topics: an agent can infer it should call this when asked about the database's scope, license, or citation format, but there is no explicit when-to-use statement, no exclusion (e.g. 'not for looking up a specific culture'), and no routing to siblings.

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