Set Test Case Scenario

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

No annotations are provided, and the description only states 'Replace all steps', implying a destructive write operation. It does not disclose any side effects, permission requirements, rate limits, or return behavior. For a mutation tool, more transparency is expected.

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 conveys the core action without fluff. It is front-loaded with the verb 'Replace', aiding quick comprehension. However, it could be slightly expanded to include minor context without losing conciseness.

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 having nested objects in 'steps' and no output schema, the description provides minimal context. It does not explain what happens after replacement (e.g., no return value) or reference related tools like 'testcase_get_scenario'. While adequate for a simple tool, more completeness would help an AI agent use it correctly.

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 coverage is 100%, with clear descriptions for both parameters ('id' and 'steps'). The tool description adds the context of 'scenario' but does not enhance understanding of parameter semantics beyond what the schema provides. Baseline 3 is appropriate.

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 'Replace all steps in a test case scenario' clearly states the verb ('replace') and resource ('steps in a test case scenario'). It distinguishes from siblings like 'testcase_get_scenario' and 'testcase_update_step' by implying a bulk replace operation. However, it could be more explicit that it replaces the entire scenario, not just some steps.

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 usage guidelines are provided. The description does not mention when to use this tool versus alternatives (e.g., 'testcase_update_step' for individual step edits). There is no context on prerequisites or scenarios where this tool is not appropriate.

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