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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the underlying endpoint (GET /bank/accounts) and, importantly given there is no output schema, the shape of each returned record. It does not say whether inactive/closed accounts are included or how pagination defaults behave.

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?

A single compact sentence front-loads the resource and its fields; nothing is redundant. The trailing 'GET /bank/accounts' is mildly useful for debugging but not strictly needed by an agent.

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 paginated read with no output schema, listing the returned fields is the essential contribution and it is present. However, ordering, inclusion of inactive accounts, and the default page size (left entirely to the schema) are unaddressed, leaving some gaps an agent would want filled.

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 schema itself documents page, per_page and the language enum with defaults and limits. The description mentions none of these, which is acceptable at the baseline when the schema carries the full burden.

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 names the specific resource (the company's bank accounts) and enumerates the fields each record carries (alias, bank, IBAN, BIC, currency), so an agent knows exactly what comes back. The 'list' verb is only implied through the name/title, and nothing distinguishes this from siblings like invbg_list_bank_transactions or invbg_list_cashboxes.

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?

There is no explicit guidance on when to use this tool versus alternatives such as invbg_list_cashboxes or invbg_list_bank_transactions, nor any prerequisites (e.g. whether an authenticated firm context is required). Usage is only inferable from the tool name and the listed fields.

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