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

No annotations are provided, so the description carries the full behavioral burden for a 51-parameter mutation. It says nothing about what happens on failure, whether a payment method is required, idempotency, confirmation semantics, or the effect of bookIfPaymentOnFile. "Authenticated customer" is the only auth hint offered.

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?

Two sentences, zero waste, with the core action front-loaded and the prerequisite sequencing following immediately. Nothing redundant or padded.

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 tool with 51 parameters, nested objects, no annotations, and no output schema, the description is thin. It omits how the many optional fields relate to category/serviceType, what the call returns, and what confirmation behavior to expect, leaving the agent under-informed for a write operation.

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 only 16%, so the description must compensate and largely does not. It adds a useful note about durationHours coming from calculate_quote, but that is already in the schema, and the dozens of optional booleans/numbers (edging, garage, yardSize, windowPanes, etc.) go unexplained.

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 verb and resource ("Create a service order") and scopes it to "the authenticated customer." It also distinguishes itself from the calculate_quote sibling by establishing the create-after-quote relationship, so an agent can place it in the workflow without opening the schema.

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?

Gives an explicit prerequisite and ordering: call calculate_quote first for price and durationHours, then call this once the customer agrees. It names the alternative tool and the triggering condition. It does not cover when-not-to-use (e.g. reschedule_job/cancel_job for changes), 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.
