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

No annotations are provided, so the description carries full burden. It states it's a list operation but doesn't disclose behavioral traits like pagination, sorting, rate limits, authentication needs, or what 'all environments' entails (e.g., archived ones). This leaves significant gaps for a tool with potential complexity.

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, efficient sentence that front-loads the core action ('List all environments') and immediately clarifies scope. There is zero waste, and every word earns its place, making it highly concise and well-structured.

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 no annotations and no output schema, the description is incomplete. It doesn't explain return values, error conditions, or behavioral details like filtering logic. For a list tool with potential organizational scope, more context is needed to guide effective use.

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 100%, with the parameter 'projectKey' well-documented in the schema as 'Optional project key to filter environments.' The description adds marginal value by mentioning 'for a project or the entire organization,' which aligns with the schema but doesn't provide additional semantics beyond it.

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 ('List') and resource ('environments') with scope options ('for a project or the entire organization'). It distinguishes from siblings like 'get_environment' (singular) and 'list_features/projects/targets' (different resources). However, it doesn't explicitly differentiate from all list operations, keeping it at 4 rather than 5.

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 implies usage context by mentioning 'for a project or the entire organization,' suggesting when to use the optional projectKey parameter. However, it lacks explicit guidance on when to choose this over alternatives like 'get_environment' or other list tools, and no exclusions are provided.

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