validate_stack_config

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

With no annotations provided, the description must disclose behavioral traits, but it only states the action. It does not indicate whether the operation is read-only, what happens on invalid configurations, or any side effects. The only hint of behavior (conflict checking) appears in the schema, not the description, leaving a significant transparency gap.

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 sentence with no wasted words, but it is so brief that it fails to provide necessary context. It is not verbose, but under-specification makes it less useful than a concise yet informative description.

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 tool has a nested object parameter and an output schema, and the schema hints at conflict checking, but the description is too minimal to explain the validation process or when it should be used. Sibling tools and the schema provide some context, but the description alone leaves major gaps in understanding what the tool does and returns.

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 both parameters already described ('Stack configuration to validate' and 'Check for port/domain conflicts'). The tool description adds no additional meaning to the parameters, so the baseline score of 3 is appropriate.

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 'Validate a stack configuration' uses a specific verb and resource, clearly distinguishing it from siblings like create_stack and manage_stack. However, it is essentially a restatement of the tool name and does not elaborate on what validation entails, so it is clear but not maximally informative.

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 provides no guidance on when to use this tool, such as before creating a stack or to check for conflicts. It does not mention alternatives or exclusions among sibling tools, leaving the agent without context for selection.

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