get_daily_fundamentals

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

No annotations provided, so description bears full burden. It does not disclose rate limits, data freshness, authentication needs, or that it's a read-only operation. Only the purpose is stated, not behavioral traits.

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?

Description is two lines plus Args block, no fluff, front-loaded. The Args section adds value but is slightly redundant with schema. Still concise.

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 3 parameters, no annotations, but has output schema, the description covers basic purpose and parameter formats. Lacks usage guidelines and behavioral transparency, making it adequate but not fully 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 coverage is 0%, but description adds format examples (e.g., YYYY-MM-DD) and an example ticker (AAPL). However, it does not explain constraints like date ordering or allowed values beyond the schema defaults.

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 'Get daily fundamental metrics for a stock (market cap, P/E ratio, etc.)' with specific verb and resource, and distinguishes from siblings like get_fundamentals_definitions and get_financial_statements.

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 from the sibling list (e.g., get_stock_prices vs fundamental metrics). Lacks prerequisites, exclusions, or context about when this tool is appropriate.

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