Contract Testing: Create Environment

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

Annotation contradiction: readOnlyHint=true conflicts with description claiming 'Create' (a write operation). Description offers no additional behavioral details like idempotency or side effects beyond contradictory annotations.

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?

Short and front-loaded with clear action. Parameter list is redundant with input schema but not excessive. One sentence for purpose plus structured parameter list. No waste.

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?

No output schema; description fails to mention return value (e.g., the created environment object). Missing info on error conditions or idempotency behavior. Toolset grouping helps but incomplete for a creation 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?

Schema coverage is 100%, so baseline 3. Description lists parameters with minimal enhancements (e.g., example values for name) but adds little beyond schema descriptions. No significant value added.

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?

Clearly states 'Create a new deployment environment in PactFlow' - a specific verb (create) and resource (deployment environment) with system context. Distinguished from sibling tools like update_environment and delete_environment.

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 explicit guidance on when to use this tool vs alternatives (e.g., update_environment). No prerequisites or context provided. The toolset header gives some grouping but no actionable usage direction.

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