openfinance_list_investment_transactions

Read-onlyIdempotent

Returns the movement history for a specific investment position: BUY / SELL / TAX / INTEREST / AMORTIZATION / TRANSFER. Each row carries quantity, value, amount, netAmount, agreedRate (treasury), brokerageNumber, and itemized expenses (brokerageFee, incomeTax, settlementFee, custodyFee, stockExchangeFee, etc.). Use after openfinance_list_investments to get the investment_id.

Bulk support: accepts investment_ids for batched execution.

TDQS

A4/5.0
Behavior4/5

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

Annotations already indicate read-only and idempotent behavior. Description adds detail about returned fields and bulk execution, providing value beyond structured data.

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

Conciseness5/5

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

Two focused paragraphs with no wasted words, front-loading core functionality and following with usage guidance.

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

Completeness3/5

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

Describes return fields and movement types well, but lacks information on pagination behavior and does not fully cover all parameters.

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

Parameters2/5

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

Schema has 0% description coverage. Only investment_id and investment_ids are explained; page and page_size are undocumented, leaving semantic gaps.

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?

Clearly states it returns movement history for investment positions, listing specific transaction types. Distinguishes from sibling tools like openfinance_list_investments.

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?

Explicitly instructs to use after openfinance_list_investments to obtain investment_id. Mentions bulk execution support, but does not state when to avoid this tool.

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

A4.2/5.0
Disambiguation5/5

Every tool has a clearly distinct purpose: accounts, transactions, credit card bills, loans, investments, connections, sync, categories, provider status, and platform meta-tools are all separable. Even the two transaction tools differ (per-account list vs consolidated analysis) and the two status tools differ (connection vs provider health).

Naming Consistency4/5

The openfinance_* prefix is consistently applied across the financial domain, and most follow a verb_noun pattern (list_accounts, get_balance, update_category). However, there are non-prefixed tools (authenticate, connect, marketplace, toolkit_info) and one outlier like openfinance_provider_status (noun instead of verb) that slightly break the pattern.

Tool Count3/5

25 tools is at the upper boundary of what feels heavy for a single server, even for a comprehensive financial aggregation toolkit. The number is justified by the breadth of domains covered (accounts, credit, loans, investments, connections, platform features), but it requires careful agent selection and might be better split into separate servers.

Completeness5/5

The surface covers the full financial data lifecycle: listing and fetching details for all asset types, updating transaction categories, managing connections (list, sync, disconnect, reauth), checking provider health, and searching connectors. There are no obvious dead ends—every domain has read and appropriate write/update operations.
