v1.3.2Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It does add useful context by noting this is 'live data' and specifying the returned fields, but it does not state whether the operation is read-only, whether there is pagination, or how errors/latency may behave.
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 two sentences with no filler. The primary action and scope are front-loaded, and the follow-up sentence adds value by listing return fields and a use case.
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?
For a simple, parameterless list tool, the description provides all essential context: what it lists, where the data comes from, what fields are returned, and when to use it. No output schema exists, but the description compensates by summarizing the output.
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?
The tool has zero parameters, so parameter semantics are inherently trivial. The baseline for no-parameter tools is 4, and the description adds no misleading or unnecessary parameter information.
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 uses a specific verb ('List all bills') and clearly identifies the resource (bills from Rentvine) and scope. It also enumerates the returned fields, making the tool's purpose unmistakable even among many sibling list tools.
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?
The phrase 'Use this to review outstanding vendor invoices' provides a clear context for when to invoke the tool. It does not explicitly exclude alternatives or mention when not to use it, but for a zero-parameter list tool this context is sufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
