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

Adds real context beyond the readOnlyHint/destructiveHint/openWorldHint annotations: it states that authentication is required despite being non-destructive, that no quote allowance is consumed, that no purchase occurs, and that the response carries configuration, review revision, warnings and a browser link. The only mild tension is 'revise' suggesting a write while readOnlyHint=true — likely because the draft is not persisted, but the description never says so.

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?

Four tight sentences with no filler. Slight weakness is ordering: the product description leads and the actual verb ('Prepare or revise an editable draft') lands second, so the action is not fully front-loaded.

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 values need not be enumerated, yet the description still names the key payload elements. Auth requirements and the no-purchase/no-quote guarantees are covered; the only gap is explicit sibling routing for the eventual pricing step, which matters given the quote_gripper sibling.

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 every nested configuration field already carries a description plus min/max bounds, so the schema does the heavy lifting. The description adds only that omitted fields fall back to Gripper Lab defaults (echoed in the schema) and that lengths are millimetres, so baseline 3 is appropriate.

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?

States a specific resource (compliant gripper kits, two TPU pads / two rigid carriers / two keepers per kit) and a specific action (prepare or revise an editable draft). It partially distinguishes itself from the quote_* siblings via 'no quote allowance' and 'No purchase occurs', but never names quote_gripper as the pricing alternative.

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?

'Prepare or revise an editable draft' implies the create/revise use case, and 'No purchase occurs' plus 'no quote allowance' implies the boundary against quote_gripper and checkout. However the routing is left to inference — no explicit 'use quote_gripper when you need a price' statement.

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