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

Annotations already declare destructiveHint=true, idempotentHint=false, and readOnlyHint=false, so the safety profile is largely covered by structured data. The description adds the useful side-effect that list also returns accessible workspaces, but it never warns that update can overwrite project fields (e.g. tags replacing the full list) despite carrying the destructive hint.

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, front-loaded with the verb+resource, then the identifier workflow, then the list-return detail. No sentence is redundant and nothing is buried.

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?

Given 12 parameters, 100% schema coverage, and no output schema, the description adequately covers how to obtain and use projectId and what list returns. It omits any hint about destructive update behavior or create prerequisites, but the annotations and schema fill most of that gap.

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%, so the baseline is 3, and the description goes beyond it by explaining the projectId lifecycle (obtain via list, then reuse for update and other project-scoped tools). It adds workflow meaning but no additional format or constraint detail for the remaining 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 states specific verbs and a clear resource ('List, create, or update AdKit projects'), so the agent immediately knows this is the CRUD entry point for projects. It does not explicitly contrast itself with siblings like adkit_manage or adkit_setup, but the resource-level specificity is strong.

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 gives real workflow guidance: use a projectId from list for update, note that list returns accessible workspaces, and (in the schema) that action defaults to list and create is for when no project exists. There is no explicit when-not guidance or named alternative sibling, which keeps it short of a 5.

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