A4/5.0
Behavior3/5

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

No annotations are provided, so the description carries full burden. It discloses the output format and that it returns current date, but lacks details on behavioral traits like timezone handling, freshness guarantees, or error conditions. However, for a simple read-only tool with no parameters, this is minimally adequate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with zero waste—it directly states the tool's purpose and output format. Every word earns its place, making it highly efficient and easy to parse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (0 parameters, no annotations, no output schema), the description is complete enough for a basic date retrieval function. It specifies the exact format, which compensates for the lack of output schema. However, it could slightly improve by mentioning timezone or freshness aspects.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are 0 parameters, and schema description coverage is 100%. The description does not need to add parameter semantics, so it appropriately focuses on output. Baseline for 0 params is 4, as it efficiently describes the tool's function without unnecessary parameter details.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific verb ('Get') and resource ('today's date'), with precise format details ('ISO 8601 format (YYYY-mm-dd.HH:MM:SS.000Z)'). It distinguishes from sibling tools (like create_entities_batch or query_database) by focusing solely on retrieving current date information.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context (when you need today's date in a specific format), but does not explicitly state when to use this tool versus alternatives or any exclusions. No guidance on prerequisites or comparisons with other date/time tools is provided.

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