stock_quote

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

No annotations provided, so the description carries full burden. It discloses the real-time nature but omits details like rate limits, data freshness, authentication requirements beyond the api_key parameter, or any limitations.

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?

Single sentence, no fluff, but too terse for a tool with multiple parameters and no explanations. The structure is straightforward but insufficiently informative.

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 no output schema and missing annotations, the description should cover expected output format, error handling, and parameter constraints. It does not, leaving the agent underspecified for autonomous use.

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%. The description adds no meaning to the parameters 'symbol' and 'api_key' beyond their names; the agent is left to infer that 'symbol' is a stock ticker and 'api_key' is for authentication.

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 action 'Get', the resource 'real-time stock quote', and the source 'Alpha Vantage'. It distinguishes from sibling tools like stock_daily (historical daily data) and stock_search (search for symbols) by specifying 'real-time', but does not explicitly differentiate.

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?

No guidance on when to use this tool versus alternatives such as stock_daily or stock_intraday. Lacks information about prerequisites, e.g., needing an Alpha Vantage API key.

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