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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful context (it returns raw model geometry in STL/OBJ/3MF and requires an authenticated quote), but says nothing about missing-quote errors, binary/file delivery, or auth failure behavior beyond 'authenticated'.

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?

A single compact sentence with the core action and resource front-loaded and no filler. It is efficient, though it leaves room to say more without becoming verbose.

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?

An output schema exists (so return shape needn't be described) and annotations fully carry the safety profile. What remains useful to state — that this fetches the original model file for an authenticated quote — is present, leaving no critical gap for calling it correctly.

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 quoteId and accessToken are fully documented in the schema (including their source tools). The description adds no parameter-level detail, so the baseline 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?

Specific verb (read) plus a well-defined resource (the original STL/OBJ/3MF file belonging to an authenticated print quote), which is meaningfully different from printing.quotes.get that returns quote metadata. It does not explicitly name or contrast a sibling, so it stops short of 5.

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?

'for the quote review app' gives an implied context for when this is called (rendering a model preview during review). However, there is no explicit when-to-use, when-not, or routing versus siblings like printing.quotes.get, leaving usage to inference.

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