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

Annotations already cover the safety profile (readOnly, non-destructive, closed-world), and the description adds real value on top: authentication is required but consumes no quote allowance, no purchase occurs, simulation is unavailable, and the return payload (configuration, review revision, warnings, browser link) is sketched. This is meaningful context beyond the structured fields.

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?

Six short sentences, front-loaded with the core action and followed by scoping constraints; nearly every clause carries information. The telegraphic fragments ('Simulation is not exposed', 'No purchase occurs') are terse but not wasteful.

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 draft-preparation tool with a full output schema, the description covers the essentials: auth model, absence of quoting/purchase, simulation exclusion, and return contents. It stops short of naming sibling alternatives or revision semantics, but nothing critical for a correct invocation 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?

Schema description coverage is 100% and an output schema exists, so the schema already documents the seven inputs, including the artwork mask format and normalized geometry note. The description adds no per-parameter semantics of its own, so the baseline of 3 applies.

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 first sentence states a specific verb+resource (prepare matched lower/upper stamping dies via the approved print process) and the scoping notes ('Simulation is not exposed', 'no quote allowance') help separate it from quote_stamping. The phrasing 'Matched lower and upper stamping dies' is grammatically awkward and reads like a fragment, but the intent is recoverable.

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 implies usage ('Prepare or revise an editable draft') and scopes out simulation, quoting and purchase, but never explicitly says when to pick this over quote_stamping or the other prepare_* siblings. It is enough to place the tool in the draft-vs-quote workflow, but no exclusions or alternatives are named.

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