get_balance

Retrieve asset balances from your Bitvavo account, showing available and in-order amounts. Optionally include zero balances for a complete overview.

Instructions

List balances per asset on the Bitvavo account. Each entry has symbol, available (free to use), and inOrder (locked in open orders). Zero balances are filtered out unless include_zero=true.

Tool call template

TDQS

A4.5/5.0
Behavior4/5

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

With no annotations provided, the description discloses key behaviors: it lists what each entry contains and explains that zero balances are filtered out unless include_zero=true. It does not mention rate limits or authentication, but for a read-only list tool, the behavior is adequately transparent.

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 two sentences, front-loaded with the primary purpose and followed by output detail and parameter behavior. Every sentence adds value without any filler.

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?

Despite lacking an output schema, the description specifies the output structure (symbol, available, inOrder) and the behavior of the only parameter. For a simple list tool, this is sufficient for an agent to invoke and interpret results correctly.

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 schema has one parameter, include_zero, with no description. The description compensates by explaining its effect: zero balances are filtered out unless include_zero=true. This adds meaning beyond the bare boolean type.

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 'List balances per asset on the Bitvavo account,' specifying the resource and scope. It also details the output fields (symbol, available, inOrder), distinguishing it from sibling tools like get_portfolio_value or get_ticker.

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 clear context for when to use this tool: to retrieve account balances per asset. However, it does not explicitly mention alternatives or when not to use it, so it lacks explicit exclusion guidance.

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