TDQS

D1.7/5.0
Behavior1/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Ultimate Oscillator' reveals nothing about whether this is a read-only operation, what data source it uses (Alpha Vantage), what permissions are required, rate limits, or what the output looks like. For a financial data tool with no annotation coverage, this is completely inadequate.

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

Conciseness2/5

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

While technically concise with just two words, this is a case of under-specification rather than effective conciseness. The description fails to provide any meaningful information that would help an AI agent understand or use the tool. Every sentence should earn its place, but here there's essentially no useful content to evaluate.

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 financial technical indicators, no annotations, no output schema, and a completely inadequate description, this is severely incomplete. The description doesn't explain what the Ultimate Oscillator is, how it's calculated, what it measures, or what the output represents. For a tool that presumably returns complex financial analysis data, this description is completely inadequate.

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

Parameters3/5

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

Schema description coverage is 100%, meaning all parameters are documented in the input schema. The description adds no parameter information beyond what's already in the structured schema. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no param info in the description.

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

Purpose2/5

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

The description 'Ultimate Oscillator' is a tautology that restates the tool name without explaining what it does. It doesn't specify the action (e.g., 'calculate', 'retrieve', or 'analyze') or clarify that this is a technical indicator for financial analysis. While the name suggests it's related to technical indicators, the description adds no meaningful clarification beyond the name itself.

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

Usage Guidelines1/5

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

The description provides no guidance on when to use this tool versus alternatives. With many sibling tools in the technicalIndicators category (like sma, ema, bbands, etc.), there's no indication of what makes the Ultimate Oscillator unique or when it should be preferred over other technical indicators. The description offers zero usage context.

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