generate_feature_file

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool generates a file but does not cover critical aspects such as file overwriting behavior, error handling, permissions required for saving to 'output_path', or what happens if the path is invalid. This is inadequate for a tool that creates files.

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 a single, efficient sentence that directly states the tool's purpose without redundancy. It is appropriately sized and front-loaded, with no wasted words, making it easy for an agent to parse quickly.

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 complexity of file generation with no annotations or output schema, the description is incomplete. It lacks information on behavioral traits (e.g., file creation/overwrite rules), error conditions, and output details, which are essential for safe and effective tool invocation in a testing context.

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 input schema has 100% description coverage, providing clear details for all 4 parameters. The description adds no additional semantic context beyond implying Gherkin syntax usage, which is already covered in the schema. This meets the baseline of 3 when schema coverage is high.

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 purpose: 'Generate WDIO feature file with Gherkin syntax (Given, When, Then)'. It specifies the verb ('Generate'), resource ('WDIO feature file'), and syntax format ('Gherkin syntax'), but does not explicitly differentiate it from sibling tools like 'generate_component_file' or 'generate_page_file', which prevents a score of 5.

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 provides no guidance on when to use this tool versus alternatives. It does not mention sibling tools like 'generate_steps_file' or 'process_test_scenario', nor does it specify prerequisites, exclusions, or contexts for usage, leaving the agent with insufficient direction.

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