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

No annotations provided, so description must disclose behavioral traits. It implies a read operation ('Get') but does not explicitly state read-only, nor does it mention side effects, permissions, rate limits, or data freshness. The description adds no behavioral context beyond the obvious.

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 with two sentences plus parameter list, no wasted words. However, the 'Args:' block is slightly informal and could be integrated more smoothly. Overall, front-loaded and 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 the tool's low complexity (3 params, output schema exists), the description covers purpose and parameters adequately. But it lacks context on what the output contains, authentication needs, or when this tool is preferred over siblings. Output schema may mitigate some completeness needs, but description still falls short.

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?

The input schema lacks descriptions for properties, but the description adds meaningful explanations for all three parameters: account_hash (source), start_date and end_date (optional, date format). This adds value beyond the schema, though schema coverage is reported as 0%.

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 tool retrieves stock loan payments for a Schwab account, using a specific verb ('Get') and resource ('stock loan payments'). The name includes 'schwab' which differentiates it from sibling tool 'stock_loan_payments'.

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 like the generic 'stock_loan_payments' tool. No prerequisites or exclusions mentioned beyond needing an account hash from another tool.

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