anaf_nomenclator_localitati

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

Annotations already cover the safe read-only, idempotent profile. The description adds genuinely useful context beyond them: the data is public (no auth) and served from a local mirror, which hints at possible staleness and avoids unnecessary auth attempts.

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 dense sentences front-load the resource and returned fields, then the filtering behavior. Nothing is wasted, though the parenthetical XSD reference makes the opening slightly heavy.

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 no output schema, the description names the returned fields and clarifies locality vs county scope, which is enough for correct invocation. It could be more explicit about sibling choice, but no critical information is missing.

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 coverage is 100%, but the description still adds meaning: it clarifies that q matches by name, is diacritics-insensitive, and gives concrete examples ('sector 6', 'cluj'), which the bare 'Name filter' schema description does not. County parameter semantics are left to the schema, which already has an example.

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 specific resource (locality nomenclator for a county) and names the exact fields returned (cod_localit, SIRUTA, town-hall codes), so its output is identifiable. Sibling differentiation is implicit rather than explicit, but 'locality' versus 'judete' and 'strazi' is clear enough from the name and first clause.

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?

The use case is implied by 'as required by declaration XSDs, e.g. C168 cod_localit_L', which tells the agent when this data is needed. It does not say when to prefer this over anaf_nomenclator_judete or anaf_nomenclator_strazi, so the routing guidance is incomplete.

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