Create an environment

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

The description adds valuable behavioral context beyond annotations: request body size limit (30MB), handling of 411 error, default workspace selection, and the limitation on modifying only shared variable values. These details help the agent understand side effects and constraints without contradicting the readOnlyHint=false annotation.

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 main description is concise, and the note is structured with bullet points. However, the note about shared variables is lengthy and could be trimmed, though it is relevant. Overall, it is not excessively verbose.

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?

The description covers operational details like size limits and error handling, but it does not mention the success return value or any prerequisites. The workspace parameter discrepancy (optional in description vs required in schema) leaves some ambiguity. Given the tool's complexity and lack of output schema, more detail on creation outcomes would be helpful.

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 is 3. The description adds meaningful semantics for the workspace parameter (defaults to oldest personal Internal workspace when omitted) and for the values parameter (only shared variable values can be modified via API). However, there is a contradiction: the schema marks workspace as required, while the description implies it is optional, which could confuse the agent.

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 starts with 'Creates an environment.' which clearly states a specific verb and resource. It distinguishes from sibling tools like createCollection and createWorkspace by specifically targeting 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 description provides context about default workspace behavior and error handling, but does not explicitly state when to use this tool versus alternatives (e.g., updateEnvironment). There is no mention of exclusions or comparison with sibling create tools.

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