A4.3/5.0
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true. The description adds value by specifying the exact information returned (platform and adapter versions), which is beyond what the annotations provide.
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?
The description is a single sentence with 8 words, extremely concise and front-loaded. Every word is necessary and adds value, meeting the criterion that every sentence should earn its place.
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?
For a simple version retrieval tool with no parameters, the description is complete. It fully explains what the tool does, and no output schema is needed as the return value is obvious from the description.
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?
The tool has zero parameters, and according to guidelines, a baseline of 4 is appropriate. The description correctly indicates no input is needed, and the schema coverage is 100%, so no additional parameter information is required.
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 uses a specific verb 'Show' and clearly identifies the resource: 'MCP platform and adapter versions.' It effectively distinguishes from sibling tools which are all about authentication, finance operations, or other functionalities.
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?
No explicit guidance on when to use or not use this tool, but the context makes it obvious. The tool's purpose is self-explanatory, and there are no alternative version tools among siblings, so implicit usage is clear.
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
Most tools have clearly distinct purposes, especially within the openfinance_* family where each targets a different resource or action. A few minor overlaps exist—connect vs toolkit_info both report connection state, and marketplace internally includes report_bug while a top-level report_bug also exists—but these are unlikely to cause serious misselection.
Naming Consistency4/5
The openfinance_* tools follow a consistent snake_case prefix with mostly verb_noun patterns like list_accounts, get_item_status, and force_sync. The general tools are also snake_case but mix verbs (connect, authenticate) with nouns (marketplace, toolkit_info), and openfinance_provider_status breaks the verb_noun pattern slightly.
Tool Count3/5
25 tools is at the upper boundary of a heavy surface, but the Open Finance domain genuinely spans connections, accounts, transactions, bills, loans, investments, categories, and provider health. It feels dense rather than bloated, though a few general utilities like show_version and report_bug could arguably be consolidated.
Completeness4/5
The Open Finance surface is well covered: connection management, account/balance/transaction retrieval, credit card bills, loans, investments, category correction, force sync, and provider status are all present. Minor gaps exist—such as no direct investment position detail endpoint beyond the portfolio list, and payments/initiation are out of scope—but agents can accomplish the core read-only financial workflows without dead ends.
