v1.17.7Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses that it returns the 'complete article-bearing Stock Market News section set', which tells the agent what to expect. It does not explicitly state read-only nature or return format, but 'List' implies a safe read operation.
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?
Two sentences, front-loaded with the core action and followed by a scoping detail that ties it to a sibling tool. No redundant or filler content.
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 listing tool with no output schema, the description adequately conveys purpose and return content. It stops short of detailing the exact return format (e.g., list of strings vs objects), but that is a minor gap for such a simple tool.
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 takes zero parameters, so there are no parameter semantics to clarify. Baseline is 4 when there are no parameters.
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?
States a specific verb ('List') and resource ('The Motley Fool news sections'), and distinguishes itself by linking to the sibling tool motleyfool_headlines. An agent can tell this lists sections rather than articles or headlines without opening a schema.
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 description says the returned section set is 'accepted by motleyfool_headlines', which clearly signals the tool's role as a companion for that sibling. However, it does not explicitly say when to use this versus other Motley Fool tools or state any exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
