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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the baseline burden is lower. The description adds useful behavioral context: generation is restricted to verified/accepted plans, and STEP is currently not supported. There is no contradiction with the annotations; the word 'generates' can reasonably refer to deterministic, read-only artifact generation.

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 compact sentence with no filler, and the core constraint is front-loaded. The unexplained capitalized terms reduce clarity slightly, so it is not a perfect 5, but it is appropriately concise.

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 output schema and annotations present, safety and return behavior are largely covered, and the precondition is helpful. However, the description lacks parameter semantics, does not name alternatives among the many sibling tools, and leaves 'LIVE' and 'STEP' unexplained, so an agent still has meaningful gaps to resolve.

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%, so the description needed to compensate, but it does not explain solutionId, format, or entitlement. It only gestures at 'formats' generically, leaving the agent to infer parameter meaning from enum names and property schema. That is insufficient for low-coverage schemas.

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 uses a specific verb ('Generates') and the title supplies the resource ('artifact'), while the text scopes the operation to 'LIVE deterministic formats' and 'after plan acceptance and verification.' It also excludes STEP, which distinguishes the tool from a general generate action, though 'LIVE' and 'deterministic formats' remain jargon-heavy and not fully explicit.

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 gives an explicit precondition ('after plan acceptance and verification') and a clear when-not ('STEP remains unavailable'), and the word 'only' narrows the tool's applicability. It does not explicitly name sibling tools or alternative routing, which keeps it just short of the top level.

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