Create Bank Account

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

Annotations indicate readOnlyHint=false and destructiveHint=false, but the description adds no behavioral context such as whether the operation is reversible, requires specific permissions, or triggers side effects like notifications or recalculations.

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 extremely short but ineffective. It merely restates the tool's name, wasting the opportunity to convey meaningful information. True conciseness balances brevity with informativeness.

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 5 parameters (2 required), no output schema, and many siblings, the description fails to explain return values, scope of creation, or any constraints. It leaves the agent guessing about the tool's overall behavior.

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 coverage is 100% with descriptions for all 5 parameters, so the description does not need to add parameter details. It neither contradicts nor supplements the schema, meeting the baseline but adding no extra value.

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 'Create a bank account' is a tautology of the name and title. It provides no additional detail about what creating entails, such as what fields or constraints apply, and does not distinguish it from sibling tools like get_bank_account, update_bank_account, or delete_bank_account.

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 is given on when to use this tool versus alternatives like update_bank_account or list_bank_accounts. There is no mention of prerequisites, required data, or context for invocation.

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