Create environment

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

Annotations already indicate the tool is not read-only (write operation) and not destructive. The description adds no behavioral context beyond stating the action. Missing details such as whether the tool fails if the environment already exists, what permissions are required, or what the response looks like.

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 sentence with no unnecessary words, front-loading the action. However, it could be slightly more informative without losing conciseness, such as hinting at required fields or typical use cases.

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 creation tool with 3 parameters, no output schema, and many sibling environment tools, the description lacks completeness. It does not mention what constitutes a valid environment, uniqueness constraints, or the result of creation. More context is needed for sufficient guidance.

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?

The input schema covers all 3 parameters with descriptions (100% coverage), so the schema already provides the necessary meaning. The description does not add any extra context for parameters like apiUrl or tlsEnabled beyond what is in the schema, but no additional information is needed given the schema's completeness.

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 the verb ('Create') and resource ('a new Docker environment'). It is specific enough to distinguish from other creation tools (e.g., container, network) in the sibling list. However, it does not explain what an environment conceptually represents in Arcane, leaving minor ambiguity.

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 guidance is provided on when to use this tool vs alternatives such as environment_update, environment_pair_agent, or other creation tools. There is no mention of prerequisites (e.g., Docker host availability) or scenarios where this tool should be avoided.

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