List environments

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

With no annotations provided, the description must disclose behavioral traits. It only states that the tool requires a project UUID, which is a parameter prerequisite rather than a behavioral detail. It does not mention return values, pagination, permissions, or side effects, leaving the agent with a minimal understanding of the tool's runtime behavior.

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 that is direct and front-loaded. It contains no redundant words and effectively communicates the core purpose and a key prerequisite. It is concise without being under-specified.

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 list tool with one parameter and no output schema, the description is adequate but has gaps. It does not explain what the tool returns (e.g., a list of environment objects) or address the confusion caused by the sibling 'listEnvs'. Including a note about the return type or differentiation 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?

The input schema has one parameter 'uuid' with no description (0% coverage). The description adds meaning by stating that this parameter is the project UUID, clarifying its role. However, it does not provide additional details such as format or validation rules, so the compensation is partial.

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 tool's function: 'List all environments for a project.' It uses a specific verb and resource, and the scope 'for a project' adds clarity. However, it does not differentiate from the sibling tool 'listEnvs', which appears to have an overlapping purpose.

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 no guidance on when to use this tool versus alternatives like 'listEnvs'. It only mentions a required prerequisite (project UUID) but does not discuss context, alternatives, or exclusions. This leaves the agent without decision-making information.

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