TDQS

C2.1/5.0
Behavior1/5

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

With no annotations provided, the description carries full burden but fails to disclose behavioral traits. It doesn't mention whether this is a read-only operation, potential rate limits, authentication needs, error handling, or what 'fetch' entails (e.g., returns historical data, current status). This leaves critical behavioral aspects unspecified.

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 extremely concise with a single phrase, 'Fetch digital currency weekly', which is front-loaded and wastes no words. While it may be under-specified, it earns full marks for brevity and structure.

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

Completeness1/5

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

Given the complexity of a financial data tool with 2 parameters, no annotations, and no output schema, the description is incomplete. It doesn't cover parameter meanings, behavioral aspects, or expected outputs, making it insufficient for an agent to use the tool effectively.

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

Parameters1/5

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

The input schema has 0% description coverage, with two required parameters ('symbol' and 'market') undocumented. The description adds no meaning beyond the schema, failing to explain what these parameters represent (e.g., currency symbol like BTC, market like USD) or their expected formats, which is inadequate given the low schema coverage.

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

Purpose3/5

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

The description 'Fetch digital currency weekly' states a verb ('fetch') and resource ('digital currency weekly'), making the purpose understandable. However, it's vague about what 'weekly' means (e.g., weekly data, weekly frequency) and doesn't differentiate from siblings like 'digital_currency_daily' or 'digital_currency_monthly', which is a missed opportunity for clarity.

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 guidance is provided on when to use this tool versus alternatives. The description lacks context such as use cases, prerequisites, or comparisons to sibling tools like 'digital_currency_daily' or 'crypto_intraday', leaving the agent without direction on selection.

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