pex_get_advanced_account_details

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

With no annotations provided, the description carries full burden but discloses only the basic read operation. It fails to explain what data fields 'advanced' encompasses, whether the operation is idempotent, or any rate-limiting concerns.

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?

Extremely concise at 9 words with front-loaded verb. However, extreme brevity contributes to under-specification regarding behavioral traits and sibling distinctions, preventing a 5.

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?

With no output schema and no annotations, the description should disclose the return content to distinguish 'advanced' details from standard ones. It fails to compensate for these missing structured fields, leaving significant gaps.

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?

Input schema has 100% coverage with the 'id' parameter fully described as 'Account ID'. The description references 'by account ID' reinforcing usage but adds no additional semantic details (e.g., ID format, where to find it) beyond the schema.

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?

States a clear verb ('Get') and resource ('advanced cardholder account details'), but does not explain what distinguishes 'advanced' details from the sibling 'pex_get_account_details', leaving sibling differentiation to naming convention only.

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?

Provides no guidance on when to use this 'advanced' version versus the standard 'pex_get_account_details' or 'pex_get_all_account_details' siblings, nor any prerequisites or exclusions.

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