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

The description is consistent with annotations: readOnlyHint=true and destructiveHint=false, as validation is a read-only operation. The description adds no new behavioral insights beyond the annotation; it merely restates the command. There is no contradiction, but the description does not enhance understanding of potential side effects or operational nuances.

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 extremely concise: one sentence with no fluff. It is front-loaded with the core purpose. However, it sacrifices essential detail for brevity, making it slightly less useful than it could be. Given the length, it earns a high score for conciseness but not for completeness.

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?

The description lacks essential context for a validation tool: no explanation of its role in the IaC workflow, no parameter descriptions, no return value info, and no prerequisites. While annotations provide some safety context, the description fails to make the tool fully understandable or usable without external knowledge.

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?

With 0% schema description coverage, the description is expected to explain parameter meanings, yet it says nothing about 'files', 'directory', or 'init'. The agent has no clue what these parameters do or how to use them correctly. This is a critical gap for a tool with multiple optional 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's action: 'Validate OpenTofu configuration' with a reference to the underlying command. It specifies the resource (OpenTofu configuration) and aligns with the tool name. However, it does not differentiate itself from sibling validate tools like terraform_validate or packer_validate, which could cause ambiguity in selection.

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. The description solely states the function without any context on prerequisites, typical workflows (e.g., before apply), or exclusions. The agent receives no help in deciding whether this validate tool is appropriate compared to the many other validation tools in the sibling list.

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