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

With no annotations, the description must disclose behavioral traits. It only states the tool 'calculates' metrics, implying a read-only operation, but does not confirm idempotency, side effects, or authorization needs. Missing details about any destructive behavior or rate limits.

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 very concise at one sentence, but this brevity sacrifices informativeness. It could be restructured to front-load critical purpose and parameter context without excessive length.

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?

Given the tool has three parameters and zero annotations, the description is incomplete. It does not cover parameter semantics, usage context, or output details, despite the presence of an output schema.

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 0% description coverage, yet the description fails to explain any of the three parameters (source, stock_id, lookback_days). The description adds no meaning beyond parameter names and types, leaving the agent without understanding their roles.

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 clearly states the tool calculates deterministic trend, momentum, return, and volatility metrics. This distinct functionality differentiates it from sibling tools like analyze_taiwan_stock_financial_health or analyze_taiwan_stock_fundamental.

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?

The description provides no guidance on when to use this tool versus alternatives such as analyze_taiwan_stock_fundamental or get_taiwan_stock_prices. No context is given about prerequisites or typical use cases.

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