validate

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

With no annotations, the description carries the full behavioral burden and does a good job: it discloses that the operation is read-only unless fix=true, distinguishes issues from findings, and specifies that fixes never consume findings. The cryptic "review dial" reference prevents a higher score.

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?

Three short sentences deliver purpose, safety, and semantic distinctions with no filler. The phrase "Vault health check" is front-loaded, and each subsequent sentence adds behavioral value.

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 one-parameter tool with an output schema, the description covers the key aspects: purpose, safety, fix semantics, and result interpretation. The undefined "review dial" and lack of alternative-tool guidance leave small gaps, but nothing essential for invoking the tool is missing.

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 schema provides only a bare boolean named fix with zero description coverage. The description compensates by explaining that fix=true enables fixes and that default behavior is read-only, adding meaning beyond the schema. More detail on what fixes actually do would be stronger.

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?

"Vault health check" names a clear resource and operation, distinguishing validate from the CRUD and status tools among the siblings. A more explicit verb such as "run" or "perform" would strengthen it, but the intent is unambiguous.

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 phrase "Vault health check" implies when the tool should be used, and "Read-only unless fix=true" hints at how to choose the default mode. However, it never states when to prefer this over alternatives or when fix=true should be set, leaving usage partly implicit.

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