TDQS

B3.2/5.0
Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions return components (ISO format, timestamp, last trading day) but fails to disclose idempotency, timezone handling, rate limits, or whether 'last trading day' refers to a specific exchange/market.

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?

Single efficient sentence with no waste. Information is front-loaded with specific formats (ISO, timestamp) and the key trading calendar feature mentioned immediately.

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

Completeness3/5

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

Without an output schema, the description appropriately mentions the three return components (ISO time, timestamp, last trading day). However, given the financial context implied by siblings, it should specify which market's trading calendar is used or if it requires symbol-specific context.

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?

The input schema has zero parameters, establishing baseline 4 per evaluation rules. No parameter description is necessary or expected given the empty schema.

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

Purpose4/5

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

The description clearly states the tool retrieves current time information in ISO format and timestamp, plus trading calendar data (last trading day). This effectively distinguishes it from financial data siblings like get_balance_sheet. However, it lacks specificity about which market's trading calendar or timezone context.

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

Usage Guidelines2/5

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

No explicit guidance on when to use this tool versus alternatives, or prerequisites for invocation. While the financial data focus of sibling tools makes this tool's utility role somewhat implied, there is no discussion of when time/trading day data is needed versus other operations.

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