createEnvironment

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

Discloses size limit (30MB) and default workspace behavior, which adds value beyond the input schema. However, with no annotations, it's missing information on mutation effects, permissions, or reversibility. Adequate but not comprehensive.

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?

Two sentences, no fluff. The most important info (creation, size, default) is front-loaded. Every sentence adds value.

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 no output schema, the description covers key constraints but omits what the tool returns (e.g., created environment ID or object). The complexity is moderate, so a bit more detail would improve completeness.

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%, but the description adds useful extra context: 'Max size 30MB' constrains the environment object, and the workspace default clarifies behavior. This helps the agent understand parameter implications 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?

Clearly states 'Creates an environment' with specific details (max size 30MB, workspace default). Distinguishes from sibling tools like createCollection or createWorkspace by focusing on environment creation, though no explicit differentiation.

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 on when to use this tool vs alternatives (e.g., putEnvironment for updates, or when to specify workspace). The description hints at default behavior but doesn't provide context for decision-making.

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