check_environment

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

With no annotations, the description must compensate. It mentions the tool does not return the secret key, indicating a safe read operation. However, it fails to state whether the tool is read-only, requires authentication, or has any side effects like refreshing environment data.

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, concise sentence with no unnecessary words. However, it lacks structure such as breaking out parameter details or providing bullet points, which would improve readability for an agent.

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?

While the tool has an output schema that may explain the return value, the description neglects parameter guidance and usage context. Given the tool's simplicity (two params, one required), the description is minimally adequate but leaves significant gaps.

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 description coverage is 0%, so the description should explain the parameters. It does not mention the 'environment' parameter (which is required) or the 'refresh' parameter (boolean with default false). The agent is left without any understanding of how to use the parameters.

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 resolves a single Nango environment without exposing its secret key. It effectively distinguishes from sibling tools like list_environments, but uses the vague verb 'resolve' rather than a more specific action like 'fetch' or 'get'.

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 versus alternatives such as list_environments or get_connection. The description does not include any prerequisites, context of use, or warnings about when not to use it.

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