Update environment group

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

Annotations indicate readOnlyHint=false and destructiveHint=false, so the description should explain the mutating behavior. It only notes that it calls a PATCH endpoint, but does not disclose that the 'name' parameter is required (implying a full update of name) or any side effects like whether other attributes remain unchanged. The description adds minimal behavioral insight beyond the annotations.

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 contains three sentences, but the first two are redundant ('Update environment group' and 'Update the attributes of an environment group'). It wastes words without adding substance. A more concise version like 'Updates the name of an environment group' would be more efficient.

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 lack of parameter descriptions, output schema, and the tool's mutating nature, the description fails to provide sufficient context. It does not explain the return value, whether the operation is idempotent, or how to handle errors. The agent would struggle to use this tool correctly without additional documentation.

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 2 parameters with 0% description coverage, and the description does not explain them. It mentions 'attributes' but does not specify that 'name' is the only mutable attribute or that 'envGroupId' is the identifier. This leaves the agent guessing the meaning and usage of these required 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 verb 'Update' and the resource 'environment group', matching the tool name and title. It provides the API endpoint, which adds specificity. However, it does not differentiate from sibling tools like render_update_env_group_env_var or render_update_env_group_secret_file, which update sub-components of an environment group.

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 offers no guidance on when to use this tool versus alternatives. For instance, it does not mention that to update individual environment variables or secret files, one should use the dedicated sibling tools. The agent is left without context for proper selection.

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