openfinance_get_accounts_detail

Read-onlyIdempotent

Returns full account objects including extended creditData (additional cards, limits) per id (GET /accounts/:id). Pass account_ids as an array (1–50). { results, errors } batch shape. May include a provider_incident block when the Open Finance provider has an OPEN incident affecting a connected bank: credit limits and balances may be unreliable (e.g. a limit near 1,00) until the provider recovers. Do not present those values as real.

TDQS

A4.2/5.0
Behavior4/5

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

Annotations indicate read-only, idempotent, non-destructive. Description adds critical context about provider_incident blocks and unreliable data, which goes beyond annotations. Warns against presenting incorrect values.

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?

Concise with front-loaded purpose. Four sentences with no redundancy. Could slightly tighten the provider incident explanation.

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

Completeness5/5

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

Tool has one parameter, no output schema, but description covers return shape, edge cases, and usage constraints. All necessary information for agent invocation is present.

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?

Only parameter account_ids is explained with array size constraint (1–50) and meaning. Schema has 0% description coverage, so description compensates well.

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?

Description clearly states the action: returns full account objects with extended creditData per ID. Specifies the HTTP endpoint and parameter shape. Differentiates from siblings by implying it's the detail endpoint.

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

Usage Guidelines3/5

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

Provides array size limits (1–50) but no explicit comparison to sibling tools like list_accounts. Does not state prerequisites or when to prefer this tool.

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

A3.9/5.0
Disambiguation4/5

The openfinance_* tools are mostly separated by resource (accounts, bills, loans, investments, connections), and the meta tools are distinct. The main ambiguities are openfinance_list_transactions vs openfinance_list_transactions_by_item, and openfinance_get_credit_card_bill vs openfinance_list_credit_card_bills, though their descriptions do clarify different intents.

Naming Consistency3/5

The openfinance_* family follows a consistent verb_noun pattern, and the generic platform tools use bare lowercase names like connect, authenticate, and marketplace. The mixed prefixes and the occasional singular/plural variation (get_credit_card_bill vs list_credit_card_bills) make the overall namespace readable but not fully uniform.

Tool Count3/5

25 tools is at the heavy end and combines two distinct areas: platform/meta tooling and a deep Open Finance adapter. Most openfinance tools are justifed by real endpoints, but the count feels bulky for an agent to browse, and the marketplace tool packs an unusually large number of capabilities into a single entry.

Completeness4/5

The Open Finance surface is unusually complete: accounts, balances, transactions, credit-card bills, loans, investments, connection status, force sync, provider status, category correction, and disconnect are all present. The platform side is also broad via marketplace and toolkit_info, with only minor granularity gaps such as no dedicated get-single-transaction tool or separate marketplace sub-tools.
