v1.17.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must carry the full burden of behavioral disclosure. It does indicate the tool returns public data ('public Business Insider editorial section inventory'), which implies a read-only operation, but it does not explicitly state that there are no side effects, auth requirements, or rate limits. For a simple getter this is adequate but not comprehensive.
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 consists of two short sentences with no redundant content. The first sentence front-loads the action and resource, and the second adds a clarifying detail about the return value. Every sentence earns its place.
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 zero-parameter tool with no output schema, the description sufficiently communicates what the tool does and what it returns (a section inventory). It could go slightly further in describing the inventory structure, but the basic call is fully supported. An agent can correctly invoke this tool with the information provided.
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 and the schema is an empty object with 100% coverage. Per the baseline for zero-parameter tools, the description is not required to add parameter semantics. It correctly avoids discussing parameters that do not exist, leaving no ambiguity about how to invoke the tool.
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 states a clear verb ('Get') and a specific resource ('Business Insider sections'), and adds that it returns the public editorial section inventory. This is distinct from other Business Insider tools like headlines or news, though it does not name them explicitly. The purpose is unambiguous and specific enough for an agent to select it correctly.
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 is provided on when to use this tool versus alternatives such as businessinsider_headlines, businessinsider_news, or other publication section tools. The description only states what the tool does, not when it should be chosen over siblings. This leaves the agent to infer usage context from the tool name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
