Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=true, and the description reinforces read-only behavior with 'List'. It adds context on cursor-based pagination and the status filter (sent as status.in), providing useful behavioral details beyond 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?
Two concise sentences: first states purpose, second adds filtering. No wasted words, front-loaded with key action.
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?
No output schema, but the description is adequate for a list tool. It explains the endpoint and filter but does not detail return format or pagination behavior beyond cursor, which is acceptable for a simple list operation.
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%, so parameters are already well-documented. The description adds a minor detail about the status filter ('sent as status.in') but does not significantly enhance understanding 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?
The description clearly states 'List external (counterparty) bank accounts registered in Increase' with a specific verb and resource, and distinguishes from sibling list tools by focusing on external accounts. It also references the Increase API endpoint.
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 mentions filtering by status but lacks explicit guidance on when to use this tool versus other list tools. No alternatives or exclusions are provided, leaving usage context implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct resource type (account, account number, ACH transfer, etc.) with clear verb_noun naming, making them easily distinguishable.
All tools follow a consistent `increase_verb_noun` pattern in snake_case, with verbs like create, get, list, lookup.
18 tools is slightly above the typical 3-15 range, but the scope of banking operations (accounts, transfers, transactions, cards, entities) justifies the count.
The server is heavily read-only with only one mutation (create_external_account). Missing create/update/delete for accounts, transfers, cards, etc., which limits its usefulness for full banking workflows.
