anaf_nomenclator_judete

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

Annotations already declare readOnly/idempotent/non-destructive, so the bar is lower, and the description still adds genuinely useful behavior: it is served from Storno's local mirror (implying cached/possibly non-live data) and is public with no account needed. Missing only whether the mirror has a refresh cadence or staleness caveat.

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 tight sentences: the first front-loads the resource and its two content axes with illustrative codes; the second covers sourcing and access. No filler, no restatement of the tool name.

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-param lookup with no output schema, the description covers what is returned (county codes and their fiscal offices) and access conditions. It is slightly thin on return shape (flat list of counties with nested office arrays?) and on whether the whole nomenclator is returned at once.

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 zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The description correctly does not invent parameters and instead explains the shape of the returned data.

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 the resource precisely and glosses the Romanian term ('cod judet as used in declaration XSDs'), plus concretely illustrates the payload with '40 = Municipiul Bucuresti, 13 = Constanta'. It also states the second content axis, fiscal offices (organe fiscale, ufisc codes). It does not differentiate from closely named siblings like anaf_nomenclator_localitati or anaf_nomenclator_strazi, so it stops short of 5.

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?

'as used in declaration XSDs' implies the use case (filling county/office codes in declarations), and 'no account needed' removes a prerequisite. But there is no explicit when-to-use statement, no when-not, and no routing to the localitati/strazi nomenclators it sits beside in the sibling list.

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