get_stock_analysis

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

No annotations are provided, so the description carries full burden. It indicates the tool fetches data (non-destructive), but does not disclose any potential latency, rate limits, or data freshness. The output schema exists but is not referenced; description could hint at what fields are returned beyond what's in schema.

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 concise at one sentence, front-loading the key output fields. Every phrase adds value, with no waste.

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 one simple parameter and an output schema, the description could be more complete by adding a note about the ticker format or data source. It is adequate but lacks some contextual details like time zone or data provider.

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% (no description for the parameter), so the description must compensate. It does not explain what the ticker parameter expects (e.g., format, examples). However, the parameter has no enums and is simple, so the gap is small. Baseline 3 is appropriate.

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 it fetches real-time stock price, 50-day average, and analyst recommendations. The verb 'fetches' and the specific resources are well-defined, but it does not distinguish itself from sibling tools like get_historical_prices or get_stock_price_chart.

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 implies usage for obtaining current price, average, and recommendations, but provides no explicit guidance on when to use this tool versus alternatives. For instance, it does not mention that get_historical_prices might be for historical data or get_stock_price_chart for chart data.

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