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

The annotations already establish read-only, idempotent, non-destructive, and closed-world behavior. The description adds that this performs validation without publishing or running and expects publication-intent inputs, but it does not describe error behavior, validation depth, or authentication requirements.

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?

It is two sentences, front-loaded with the core action and constraint, with no redundant wording. Every sentence contributes to understanding what the tool does and what it expects.

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?

With no output schema and sparse parameter documentation, the definition leaves open what a validation result contains and how the free-form definition/settings are structured. It gives the essential pre-publication context but is not fully complete for an agent invoking or interpreting 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 description coverage is 0% and the input includes nested free-form objects. The description names definition and settings with useful publication-intent context, but it omits workflow_id entirely and gives no structural or format guidance for any parameter.

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 states a specific verb and resource: validate a workflow draft graph and execution readiness. It also distinguishes the operation from publish and run, though it does not name a specific sibling tool to use instead.

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?

It clearly frames usage as pre-publication validation without publishing or running, and instructs the caller to supply the exact definition and settings intended for publication. It stops short of explicitly naming alternative tools or when-not-to-use conditions.

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