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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds genuine behavioral context beyond that: the stock-enabled precondition (a gating condition the agent must know) and the fact that returned managements carry a work point and type. It does not mention pagination, but for a simple nomenclature list this is solid added value.

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?

A single compact sentence with the resource and precondition front-loaded, followed by the endpoint for orientation. No filler, though the endpoint reference is marginally redundant for an agent choosing a tool.

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?

No output schema exists, and the description compensates by naming the returned fields (work point and type) and the stock-enabled precondition. Together with a fully documented single parameter and a readOnly annotation, an agent has enough to call this correctly; only return-shape details like count or ordering are absent.

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% for the single required 'cif' parameter, and the schema already explains where CIF comes from (oblio_list_companies) with a format example. The description adds nothing about the parameter, so the baseline 3 for high schema coverage is correct.

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 verb+resource: listing stock managements (gestiuni) for a company, and includes the local Romanian term plus the underlying endpoint GET /api/nomenclature/management. It is clearly distinguishable from all siblings, which cover documents, clients, invoices, webhooks and other nomenclatures, though it does not explicitly name a sibling it differs from.

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 description gives one real precondition — 'works only when stock is enabled' — which tells the agent when the tool is applicable. However, it offers no guidance on alternatives or what to do when stock is disabled, and there is no explicit when-to-use framing beyond that gate.

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