get_stock_snapshot

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

No annotations provided, so description carries full burden. It discloses data source (Alpha Vantage) and content (last quote, fundamentals, OHLCV), but omits rate limits, data freshness, or error behavior. Adequate for a simple read tool.

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?

Two sentences: first states purpose and content, second adds usage note. No redundant words, front-loaded, highly efficient.

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, the description adequately lists return elements (meta, quote, fundamentals, OHLCV). Lacks details on response format but sufficient for a simple snapshot. No critical gaps identified.

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 coverage is 100%, so schema already describes both parameters (symbol and history_days). Description does not add extra parameter meaning beyond the usage disclaimer.

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?

Description clearly states the tool returns a stock snapshot from Alpha Vantage, including specific data types (meta info, quote, fundamentals, OHLCV). Verb 'Return' and resource are explicit, and there are no sibling tools to 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?

The description includes a clear usage constraint: 'Educational / demo use only.' This implies when to use and cautions against production use, though no explicit alternative tools are mentioned (none provided).

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