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

With no annotations, the description carries the full burden and does disclose important behavior: the tool does NOT place orders ('Tool-ul NU inițiază comenzi'), results are capped at a sample (limit max 5) with a webOrderUrl escape hatch, and the most-recent balance-sheet year has partial coverage. It omits auth, rate limits, and what happens on huge result sets, so it is strong but not exhaustive.

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?

The substantive paragraphs are well-ordered and earn their place, but the opening 'Keywords:' block is a long SEO-style term list that adds selection value for a human searcher, not for an agent choosing a tool. That block dilutes the front-loading; the actual purpose statement should come first.

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 35-parameter search tool with a fully documented schema but no output schema, the description adequately covers the return shape (totalCount, sample with CUI and profile URL, webOrderUrl) and the name-lookup workflow. A note about pagination interaction between offset/limit and the >5 cap would close 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?

Schema description coverage is 100%, so the schema already documents all 35 parameters including the {gte,lte,year} shape and the bsYear default warning. The description adds an overview of the filter set and the note that sorting matches the UI, but no syntax or semantics beyond what the schema provides. Baseline 3 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 names a specific verb+resource ('Caută firme românești sau identifică o firmă specifică') and states the scope precisely: the same filter set as /cauta-firme. It also differentiates itself from siblings by routing to get_company for the full profile and list_industries for industry IDs, so an agent can tell it apart from find_prospects or screen_companies.

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?

It gives an explicit when-to-use path ('Pentru a găsi o firmă după denumire, apelează cu name... apoi folosește get_company cu CUI-ul ales') and a when-not-to-use path for full exports (present webOrderUrl instead). It does not, however, distinguish itself from the many overlapping siblings like find_prospects, screen_companies, or get_screening, leaving an agent to infer the boundary.

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