test_tool_local

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

No annotations are provided, so the description carries the full burden. It discloses that the tool performs a direct HTTP GET, runs locally, and bypasses Watson Orchestrate. However, it does not mention what the response looks like, error handling, or any side effects, which is a notable gap for a testing tool.

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 three short sentences, each conveying essential information: purpose, usage triggers, and scope/exclusion. It is front-loaded, with no filler or redundant content, making it efficient and easy to parse.

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 GET testing tool, the description covers the core purpose and usage. However, with no output schema and no annotation, it leaves gaps: the return value is not described, and the 'params' parameter is unexplained. This is adequate but not fully complete for an agent to invoke it with confidence.

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%, so the description must compensate. It implicitly suggests the 'url' parameter by stating 'Test an API endpoint,' but it gives no explanation for the 'params' object. The description adds minimal meaning beyond the bare schema, and the 'params' parameter remains ambiguous in purpose and format.

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 tool's function: 'Test an API endpoint locally (direct HTTP GET).' It identifies a specific verb (test) and resource (API endpoint), and adds the scope 'locally' to distinguish it from orchestrated tools. This is a complete purpose statement that differentiates from siblings like execute_tool.

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?

Explicit usage triggers are provided: 'Use for "run locally" or "test locally".' The phrase 'Does not go through Watson Orchestrate' serves as an implicit when-not, indicating it is not for orchestrated calls. However, it does not name alternative tools explicitly, so it falls short of a 5.

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