createEnvironment

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

Annotations are consistent (non-readOnly, non-destructive, non-idempotent). The description adds significant behavioral details beyond annotations: maximum request body size of 30MB, Content-Length header requirement on certain errors, and default workspace assignment. This fully informs the agent of important runtime constraints.

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 highly concise: a single clear sentence followed by bullet-point notes. Every sentence adds necessary information without redundancy, and the main purpose is front-loaded.

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 absence of an output schema, the description covers creation behavior, error conditions, and default workspace logic. It is fairly complete, though it does not explicitly state the response format (e.g., returning the created environment object), which is a minor gap.

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 baseline is 3. The description adds value by explaining the default behavior of the workspace parameter when omitted, which is not evident from the schema alone. This enriches the parameter semantics.

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 'Creates an environment' uses a specific verb and resource, immediately clarifying the tool's function. Among sibling tools like getEnvironment, putEnvironment, and getEnvironments, it uniquely identifies the creation action, effectively distinguishing itself.

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 practical notes about request body size limits, error handling for HTTP 411, and default workspace behavior. While these offer clear context for usage, it does not explicitly contrast with alternatives like putEnvironment (update), leaving some guidance implicit.

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