get_stock_snapshot

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

No annotations are provided, so the description carries the transparency burden. It discloses the data contents but does not mention operational behaviors such as rate limits, authentication, or feed selection behavior (which is left to the schema). The description does provide a clear picture of what data is returned, but lacks behavioral depth.

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, well-structured sentence that front-loads the purpose and lists the data components without any filler. Every word earns its place.

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's moderate complexity (3 params, one enum) and the presence of an output schema, the description adequately covers what the tool returns. It could further explain that it consolidates multiple data types in one call, positioning it against individual sibling endpoints, but it is still reasonably complete.

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 100%, with each parameter (feed, symbols, currency) already having detailed descriptions including enum values and defaults. The tool description adds no extra parameter-level meaning, so the baseline score of 3 applies.

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 ('Retrieves'), the resource ('snapshots of stock symbols'), and enumerates the included data components (latest trade, quote, minute bar, daily bar, previous daily bar). This distinguishes it from sibling tools like get_stock_bars, get_stock_quotes, and get_stock_trades.

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 this is the comprehensive snapshot option, suggesting it consolidates data that individual sibling tools provide. However, it does not explicitly state when to use this tool over alternatives or mention any exclusions, so it stops short of full guidance.

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