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

With readOnlyHint already declaring the safety profile, the description still adds real behavioural context: the default 7-day window, the 90-day ceiling, the 50-result cap, and newest-first ordering. These constraints materially affect how an agent calls and interprets the tool, though pagination/truncation behaviour at the 50 cap is not spelled out.

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 tight sentence that leads with the resource and window, then the optional filter, the returned fields, and the ordering/limit. Nothing is padded and the most important constraint comes first.

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?

There is no output schema, so the description correctly compensates by listing the returned fields, and it covers defaults, caps, and sort order. It is essentially complete for a simple read tool; only behaviour at the result cap and the meaning of the CUI filter for non-matching firms is left open.

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%, so the baseline is 3. The description restates the 1-90 range and default 7 for 'zile' and reiterates the CUI filter, adding no format, matching, or semantic detail beyond what the schema properties already say.

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: alerts received from Radar within a bounded time window, and enumerates the returned fields (type, title, summary, date, company, publication). It is unambiguous on its own, but it never names or contrasts the near neighbours (alerte_surse, radar_lista, alerte_opreste/alerte_porneste), so the agent must infer the boundary from the name alone.

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?

Usage is only implied: the description tells you the tool works for a CUI-filtered or unfiltered recent window, which hints at when it fits, but there is no explicit when-to-use/when-not statement and no routing to a sibling for a different view of alerts.

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