Create a PowerOffice general ledger account

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

Adds meaningful behavior beyond the annotations by identifying the HTTP POST endpoint and, more importantly, the consent gate: confirm=true must only be set after explicit user approval. This is consistent with readOnlyHint=false and adds a practical safety constraint not present in the structured fields.

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 sentences carry the endpoint, a required-field rule, and a confirmation safeguard. Every sentence earns its place, and the most important operational constraint is front-loaded.

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 nested-object creation tool, the description covers the critical details needed to invoke it: endpoint, required VatCode/VatCodeId, and the confirmation gate. Output schema handles return values, and the remaining gaps are minor relative to the annotation coverage.

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 only 50%, and the description partly compensates by adding the external requirement that VatCode or VatCodeId be provided. However, the many nested account fields still lack explanatory context, so the description does not fully bridge the gap between the schema and the API's actual requirements.

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 the operation explicitly: 'Create one general ledger account with POST /GeneralLedgerAccounts.' The endpoint and resource make it clear which action is performed and distinguish it from siblings like poweroffice_list_general_ledger_accounts and poweroffice_update_general_ledger_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?

Provides clear usage context: VatCode or VatCodeId is required, and confirm=true is only allowed after explicit user approval of the exact account data. It does not explicitly name alternative tools or when-not-to-use conditions, so it stops short of a 5.

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