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

With destructiveHint=true already set, the description adds meaningful behavior the annotation cannot convey: a date change may fail with shortage details, and a shortage warning is only overridable via a retry with confirm_shortage. It still omits whether updates are partial, merge or replace semantics for tags, and permission requirements.

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?

Three tight sentences, front-loaded with what changes and the risky interaction, followed by the endpoint reference. The trailing 'Booqable: PUT /api/4/orders/{id}.' restates the resource without adding agent-relevant detail, a minor inefficiency.

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 an 8-parameter mutation tool with no output schema, the definition covers the mutable fields and the one non-obvious failure mode well. It would be stronger if it said whether the response returns the updated order and whether unsupplied fields are left untouched.

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 coverage is 100%, so the baseline is 3; however, the description goes beyond the schema by explaining the failure/retry relationship that gives confirm_shortage its meaning, and by grouping the parameters into editable facets (period, customer, locations, tags).

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 states a specific verb (Change) and resource (an order) and enumerates the mutable facets: rental period, customer, locations, tags. This implicitly separates it from booqable_create_order and booqable_transition_order_status, which handles status, though no sibling is named explicitly.

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?

It gives a concrete usage condition: moving dates can trigger a shortage, in which case the call fails with details and can be accepted by retrying with confirm_shortage: true. That is real when-to-use guidance, but it offers no explicit alternatives or exclusions versus related tools such as update_customer or transition_order_status.

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