encrypt_setup_atrest

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

With no annotations, the description carries full responsibility for disclosing side effects and behavior, and it provides almost none. It doesn't say whether files are written, services are enabled, keys are created, or whether elevated permissions are required.

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 single sentence is technically concise and front-loaded, but this is under-specification rather than efficient communication. It omits all behavior and parameter context while repeating the tool name's core idea.

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 security setup tool with no output schema and no annotations, the description is far too thin. An agent cannot determine the generated output, target system, side effects, or even what api_key is for, so it cannot reliably invoke this tool.

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 coverage is 50%: directory is described as 'Project directory', but api_key has no description. The description adds no parameter meaning and never explains what api_key is used for or how directory influences the generated setup.

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 names a specific action ('Generate') and resource ('encryption at rest setup'), which separates it from the sibling encrypt_setup_intransit by data posture. However, 'setup' is vague: it does not state what artifact or outcome is produced, so the agent must guess whether this creates config files, modifies cloud settings, or scaffolds code.

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 given for when to choose this tool over related siblings such as encrypt_setup_intransit or encrypt_key_management. The name implies an at-rest vs. in-transit distinction, but the description never makes this explicit or states exclusions.

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