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

Annotations already cover the safety profile (readOnlyHint, destructiveHint=false, openWorldHint). The description adds a genuinely non-obvious behavior: auctions whose submission deadline has passed stay in the list flagged with applications_closed=true. That is exactly the kind of trait annotations cannot express.

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 with no filler; the default horizon and ordering are front-loaded, and the example question and edge-case note follow logically. Slightly listy on the filter fields but every clause earns its place.

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 carries return-shape duty, and it does mention ordering and the applications_closed flag. It omits only the limit/pagination behavior, which is a minor gap for a filtered list tool with safe annotations.

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 80%, so the schema already documents days, region, category and procedure. The description restates the filter dimensions and adds the ordering semantics ('ordonate dupa data'), but adds no syntax or format detail beyond the schema, and limit remains undocumented in both places. Baseline 3 is appropriate.

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 and resource (list scheduled auctions in the next N days, default 14, ordered by date) plus the filterable dimensions. It is clear what the tool returns, though it does not explicitly name a sibling such as search_listings to sharpen the boundary.

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?

Gives a concrete triggering question ('ce licitatii sunt saptamana viitoare in Chisinau'), which tells the agent exactly when this tool fits. It stops short of naming an alternative tool or stating when not to use it, so it is clear context rather than full routing guidance.

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