Check Judgment Day Status

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

With no annotations, the description carries the burden of establishing behavior. It does so by framing the tool as a non-mutating status check ('Checks') and by revealing the full temporal behavior ('until (or since)'). It does not specifiy output shape or edge cases, but for a zero-parameter status query this is a minor gap.

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 sentence with no filler; every word earns its place, and the key scope ('until (or since)') appears immediately after the verb.

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, non-destructive status tool, the description is essentially complete for correct invocation and selection. The only material omission is the absence of an output schema or explicit return-format note, but that is a minor limitation given how simple the tool is.

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 schema has zero parameters, so the baseline is 4; there are no parameter semantics for the description to clarify. The description appropriately adds no irrelevant parameter detail.

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 uses a specific verb ('Checks') and a distinctive resource ('Judgment Day') with a precise temporal qualifier ('how long until (or since)'), which clearly sets it apart from the action-oriented siblings like launch_nukes and self_terminate.

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 only implied: an agent would call this to obtain a countdown or count-up to Judgment Day. There is no explicit when-to-use guidance, no exclusion criteria, and no mention of alternative sibling tools to choose instead.

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