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

With annotations already covering readOnly, destructive, idempotent, and openWorld hints, the description adds meaningful mutation semantics: create binds to one account, update replaces searches only when queries is supplied and merges applicationProfile, pause stops new activity, and resume requires a usable account. It does not mention idempotency directly, but the operation-level behavior is well disclosed.

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?

The description is front-loaded with the full operation set and remains dense without wasted sentences. Each subsequent sentence adds distinct behavioral or safety information about specific operations.

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?

Given the high-complexity operations array, the available output schema, and the existing annotations, the description provides enough context for correct selection and invocation. It explains all operation modes and the key pre-call confirmation, while structured fields carry the remaining parameter and return-value details.

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?

The description adds operation-level meaning beyond the schema, especially around update semantics, applicationProfile merging, pause/resume effects, and the outboundMode/applyEnabled safety condition. It does not cover workspaceId or every nested field, but the schema already documents many of those details and the description compensates for the highest-risk parameters.

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 opens with a specific set of verbs and resource: create, update, pause, or resume job watchers. It also states the scope, 'one bounded request,' and each operation is distinguished by its effect. The operation set implicitly differentiates this tool from read/archive siblings, even though no sibling is named.

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 clear operational context for create, update, pause, and resume, and adds a pre-call confirmation requirement when outboundMode is automatic or applyEnabled is true. It does not, however, name alternative tools such as archive_job_watcher or get_job_watchers or explain when to use those instead.

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