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

No annotations are provided, so the description carries full burden. It only states that the tool summarizes without recommendations, which is minimal. It does not disclose whether it is read-only, requires special permissions, or has any side effects. For a tool with no annotations, more transparency is needed.

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 a single sentence, which is concise but lacks structure. It front-loads the purpose but omits any additional context. It is not verbose, but it could be improved by adding brief parameter explanation without being lengthy.

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 3 parameters and an output schema, the description is incomplete. It does not explain what the summary contains, how lookback periods affect results, or how to interpret the output. Even with an output schema, the description should provide high-level context about the analysis.

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?

Schema description coverage is 0%, and the tool description does not explain any parameter semantics. It mentions 'valuation and monthly-revenue growth' but does not clarify how revenue_lookback_months or valuation_lookback_days affect the output. The default values are present but undeclared in meaning.

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 summarizes valuation and monthly-revenue growth without investment recommendations, which is a specific verb+resource pair. It distinguishes from sibling tools like analyze_taiwan_stock_technical or get_taiwan_stock_valuation by focusing on a combined summary without recommendations.

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 lacks explicit guidance on when to use this tool versus alternatives. It does not state prerequisites, exclude conditions, or mention sibling tools. For example, it does not clarify whether this should be used instead of get_taiwan_stock_valuation or analyze_taiwan_stock_financial_health.

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