pex_get_account_details

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

No annotations provided, so description carries full burden of behavioral disclosure. It implies read-only via 'Get' but provides no information about what fields/data are returned, error handling for invalid IDs, rate limits, or authentication requirements.

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?

Single sentence is appropriately brief and front-loaded with the verb. However, given the lack of output schema and numerous sibling tools, the extreme brevity under-provides context rather than demonstrating efficient precision.

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?

Inadequate given the tool ecosystem complexity. With no output schema and many similar account-related siblings, the description must clarify what specific data 'details' includes to enable correct tool selection, which it fails to do.

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?

With 100% schema coverage and only one parameter (id), the baseline score is appropriate. The description mentions 'by account ID' which aligns with the schema, adding minimal semantic confirmation but no additional syntax or format guidance 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 specific verb (Get) and resource (cardholder account details) with lookup key (account ID), but fails to distinguish from numerous siblings like pex_get_advanced_account_details, pex_get_all_account_details, and pex_get_account_balance, leaving tool selection ambiguous.

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 tool versus alternatives (e.g., when to use pex_get_account_balance for just balance, or pex_get_advanced_account_details for richer data). No prerequisites or exclusions mentioned.

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