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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, covering the safety profile. The description adds context about the domain (SWPC) and the inclusion of warnings, but does not describe return format, pagination, or what 'current' means (e.g., active alerts at this moment vs. a recent time window). No contradiction with annotations.

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?

The description is a single, front-loaded phrase with no filler. It efficiently conveys the tool's purpose in four words, earning its place without redundancy.

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?

For a zero-parameter tool with an output schema and strong annotations, the description is mostly sufficient. It clearly states the resource and the fact that it provides current data. However, it could be slightly more explicit about what 'current' means (e.g., a snapshot of active alerts) and how it relates to 'recent_alerts' to fully complete the picture.

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?

The tool has zero parameters, so the baseline is 4. There is no parameter semantics to explain; the description need not compensate for any schema gaps, as the schema is empty and coverage is 100%.

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 clearly identifies the resource (SWPC alerts/warnings) and implies a read-only retrieval action. It implicitly distinguishes from the sibling 'recent_alerts' through the word 'current', but lacks an explicit verb such as 'retrieve' or 'list'.

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?

No guidance is provided on when to use this tool versus alternatives like 'recent_alerts'. The word 'current' hints at a time-scoped use case, but the description does not state when to choose this tool instead of others, nor does it mention any prerequisites or exclusions.

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