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

No annotations are provided, so the description carries the full burden, and it does well: it discloses billing behavior (1 credit, not billed on miss), the data source (legislatie.just.ro / Ministry of Justice), and an accuracy caveat that consolidated forms are unofficial vs the authentic Monitorul Oficial text. It omits auth requirements and rate limits, hence 4 rather than 5.

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?

Front-loaded with the core operation, then layered with structure, edge-case notation, cost, and provenance; every sentence carries information. It reads as a dense run-on rather than cleanly separated clauses, which costs it the top score.

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 only 2 fully-documented required params and no output schema, the description usefully compensates by describing what the response contains (paragraph/letter structure, dated amendment notes). Cost, source, and authenticity caveats are covered; error/empty-result behavior and auth needs are not spelled out, so not a 5.

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 schema already supplies the same examples (171282, 291/293^1) that the description repeats, so the description adds little beyond the schema. The one marginally new detail is the caret-notation support note, but it is mirrored in the schema, keeping this at the baseline 3.

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 precise verb+resource ('One article in its current consolidated form') and disambiguates scope by giving a concrete example (Codul fiscal 171282 art. 291) plus the richness of the return (paragraph/letter structure, dated amendment notes). Scope 'article' vs the sibling get_legal_act is only implied by the singular noun, not stated explicitly, so it stops short of full sibling differentiation.

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?

No explicit when-to-use guidance versus siblings such as get_legal_act (whole act), get_legal_act_history, or search_legislation. The cost note ('Costs 1 credit; not billed if not found') is useful context, and the singular 'one article' implies a narrow fetch, but the routing decision is left to inference.

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