Contract Testing: Create Environment

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

Annotations provide no guidance (readOnlyHint=false, etc.), and the description does not disclose behavioral traits such as idempotency, side effects, or authorization requirements. It only states that it creates an environment.

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 concise: one sentence plus a parameter list. The 'Toolset' header adds organizational value without fluff. Every sentence serves a purpose.

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 creation tool, the description covers the basics. However, it does not describe the return value (no output schema) or mention constraints like name uniqueness, leaving some gaps.

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 100%, so the baseline is 3. The description repeats parameter names and short descriptions from the schema but adds no extra meaning beyond the schema.

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 'Create a new deployment environment in PactFlow', which is a specific verb-resource pair. It distinguishes this tool from siblings like list, get, update, and delete environments.

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 tool's purpose as a creation tool makes usage context obvious. However, it does not explicitly state when to use it vs. alternatives or provide any prerequisites or exclusions.

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