get_bc_balance_tool

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

No annotations are provided. The description does not disclose any behavioral traits such as authentication requirements, rate limits, side effects, or return format. For a read-only tool, the description is minimal and lacks transparency.

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

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

The description is extremely concise: one sentence of 6 words. It efficiently communicates the core purpose. However, it omits necessary context, but for conciseness alone, it is well-structured.

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

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

Given the tool has an output schema (unknown content) and no annotations, the description does not explain return values, possible errors, or the meaning of the result. The parameter is also unexplained. The definition is incomplete for an agent to use confidently.

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

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

Schema description coverage is 0%. The single parameter 'bc_id' is not described at all in the description. The description adds no meaning beyond the schema; it does not explain what a Business Center ID is or how to obtain it.

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

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

The description clearly states the action ('Get') and the resource ('Business Center balance'), adding context of 'available funds'. It is specific enough to distinguish from siblings like 'get_advertiser_balance_tool' which targets advertiser-level balances, though it does not explicitly differentiate.

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

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

No guidance on when to use this tool versus alternatives (e.g., 'get_advertiser_balance_tool' or 'get_bc_account_cost_tool'). No context about prerequisites or scenarios where this tool is appropriate or not.

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