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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful behavioral detail beyond that: default window of 7 days with a hard 90-day ceiling, newest-first ordering, and a maximum of 50 results.

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 dense sentence front-loads the resource and time window, then appends the optional filter, returned fields, ordering and cap. No filler, and the result-shape list compensates for the absent output schema.

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 and no annotations covering data shape, the description usefully enumerates returned fields plus ordering and the 50-item cap. It stops short of saying what happens when more than 50 alerts match (truncation vs pagination), which is the one operational ambiguity left.

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 both parameters are already documented, including the maximum of 90 and default of 7. The description restates the same window facts and only clarifies that CUI narrows to a single company, adding little beyond structured fields. Baseline 3 applies.

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 states a specific verb+resource: alerts received from Radar within the last N days, with an optional CUI filter, and enumerates the returned fields (type, title, summary, date, company, publication). This is clear enough to distinguish it from a write/monitoring sibling, but it never contrasts itself with adjacent tools like radar_lista or alerte_surse, which an agent must choose between.

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 context is implied by the phrasing (retrieve recent alerts in a time window), and the optional CUI is framed as 'doar pentru o firma'. However there is no explicit statement of when to prefer this over radar_lista or alerte_surse, nor any exclusion criteria, so the agent must infer routing.

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