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

No annotations are provided, so the description carries the full burden. It discloses that the tool lists all environments, including built-in ones like '_latest' and '_production' and custom ones, which adds valuable context about what to expect in the return data. However, it does not mention behavioral aspects like pagination, rate limits, or authentication requirements.

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 appropriately sized and front-loaded, with a clear first sentence stating the purpose, followed by bullet points that efficiently provide additional details without unnecessary information. Every sentence earns its place by adding 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?

Given the tool's low complexity (0 parameters, no output schema), the description is mostly complete, covering purpose, parameters, and return content. However, it lacks details on output format (e.g., structure of returned environments) and any error handling, which could be useful for an agent, though not strictly required due to the simplicity.

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 0 parameters with 100% coverage, so the schema fully documents the lack of parameters. The description explicitly states 'No parameters required,' which reinforces this and adds clarity, earning a score above the baseline of 3 for such reinforcement.

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 purpose with a specific verb ('list') and resource ('Translation Hosting environments available in your SimpleLocalize project'), and distinguishes it from sibling tools like 'get_environment_details' by indicating it returns all environments rather than details of a specific one.

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 clear context that this tool lists all environments, implying usage when a comprehensive overview is needed. However, it does not explicitly state when to use this versus alternatives like 'get_environment_details' or mention any exclusions, such as not being suitable for filtering or detailed queries.

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