wafeq_bank_accounts_create

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

Beyond the idempotentHint=false annotation, the description explains that 'calling twice creates two records' and explains how passing an idempotency_key makes retries safe. This adds useful practical behavior context without contradicting any annotations.

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 compact and front-loaded with the WRITE badge, resource path, and purpose. There is mild redundancy between 'Create bank account' and 'Endpoint for creating a new bank account,' but the overall structure is efficient and scannable.

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 simple create operation with two parameters and detailed schema descriptions, the definition covers the key endpoint, write behavior, and non-idempotency caveat. It does not explain response shape or prerequisites, but no output schema exists and the annotations plus schema already supply most necessary context.

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 idempotency_key parameter is already thoroughly documented in the schema. The main description does not add meaningful information about the body parameters; it mostly restates idempotency behavior already covered by the parameter schema, so the baseline of 3 applies.

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 explicitly states 'Create bank account' and 'Endpoint for creating a new bank account,' and the header specifies 'Bank Accounts · POST /bank-accounts/'. This clearly identifies both the operation and the resource, making it easy to distinguish from sibling bank-account tools like retrieve, update, or destroy.

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?

The description implies when to use the tool ('creating a new bank account') but does not give explicit usage conditions or alternatives. It lacks guidance on when not to use it or when to prefer a different bank-account operation, though the WRITE marker and endpoint provide some contextual direction.

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