postgrid_get_bank_account

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It usefully reveals that account and routing numbers are masked for security, a behavioral trait not evident from the schema or tool name. This adds meaningful context beyond a simple 'get' statement.

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 short, front-loaded sentences with no redundant phrasing. The first sentence states the action and target, and the second adds a valuable security-relevant behavioral detail. 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?

For a one-parameter read operation with no output schema, the description adequately covers the core purpose and the key behavioral quirk (masking). It does not list response fields or error behavior, but those are less critical for a simple get-by-ID tool, and the schema already handles parameter documentation.

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%, and the single id parameter is fully documented in the schema with an example format. The description's 'by ID' merely restates the parameter's purpose without adding new semantic detail such as ID format constraints or related object types.

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 verb 'Get' with a specific resource 'bank account details' and qualifies it with 'by ID', which distinguishes it from sibling tools like list_bank_accounts. It is direct and unambiguous, though it does not explicitly name sibling alternatives.

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?

'By ID' implicitly conveys when to use this tool: when the agent has a specific bank account identifier. However, there is no explicit comparison to alternatives such as list_bank_accounts or guidance on when not to use it, leaving the usage context somewhat implied rather than stated.

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