openfinance_list_connections

Read-onlyIdempotent

Returns the saved bank connections for this install: connector_id, item_id, bank name, a per-connection reconnect_url, and an add_connection_url to link additional banks via the Open Finance widget. The reconnect_url reopens the widget in UPDATE mode for that EXISTING connection (user re-enters credentials / MFA token and the data refreshes in place) — use it when a connection needs re-authentication (MFA connectors, LOGIN_ERROR, stale non-Open-Finance data). It does NOT consume a connection slot and does NOT require disconnecting first.

A4.5/5.0
Behavior5/5

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

Annotations already indicate readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds transparency by detailing the reconnect_url behavior (no disconnection needed, does not consume slot) and confirming the tool is a read-only listing operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, somewhat long sentence. It front-loads the main purpose ('Returns the saved bank connections for this install') but could be more concise by splitting into shorter sentences. Still, it conveys essential information without excess.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description lists several return fields and explains the reconnect_url's purpose. It does not cover potential pagination, limits, or ordering, but for a simple list tool with no parameters, it is fairly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are no parameters, so schema coverage is trivially 100%. The description adds no param-specific meaning but provides context about what the returned data contains. This meets the baseline of 4 for zero-parameter tools.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool returns saved bank connections and enumerates specific fields (connector_id, item_id, bank name, reconnect_url, add_connection_url). It distinguishes from sibling tools by focusing on listing connections rather than accounts or transactions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides context for using the reconnect_url (re-authentication, stale data) and notes it does not consume a slot. However, it does not explicitly guide when to use this list tool versus alternatives like list_accounts or list_transactions, leaving implicit that it's for connection-level info.

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

A4.3/5.0
Disambiguation4/5

The openfinance_* tools are cleanly separated by resource and action (accounts, transactions, bills, investments, loans, connections), and the list-versus-get patterns are distinguishable. The main weak spots are the broad 'marketplace' tool, which bundles many sub-actions, and mild overlap between list_accounts/get_account_balance and list_transactions/list_transactions_by_item.

Naming Consistency4/5

The banking tools follow a consistent openfinance_<verb>_<noun> convention, with list_/get_ prefixes used predictably. A few deviations like 'provider_status' (missing a verb) and non-prefixed platform tools (authenticate, connect, marketplace, toolkit_info) keep it from being perfectly uniform.

Tool Count4/5

25 tools is on the heavy side, but the Open Finance domain justifies a wide surface: balances, transactions, bills, investments, loans, connections, sync, and provider health each need their own entry points. The platform/meta tools add some bulk but are individually useful.

Completeness5/5

The Open Finance surface covers the full read lifecycle: discover/search connectors, connect via URLs, list and inspect connections, force sync, check provider/connection status, and read accounts, balances, transactions, credit card bills, investments, and loans. It also supports the one clearly expected write operation (transaction category correction), leaving no obvious dead ends in the core domain.
