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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the ordering behavior ('most recent first') and the returned field set, which is genuine value beyond the annotations, but it does not discuss pagination limits, default page size, or result caps at the behavioral level.

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 front-loaded sentences: the first states what is returned and in what order, the second states filters and purpose. No filler or restatement of the title.

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 read-only list tool with full schema coverage and annotations covering safety, the description is nearly sufficient — it explains output fields, ordering, filtering, and pagination, and points at the job_id token needed for follow-up calls. It stops short of naming get_job_status/get_job_results as the next step, which is the one remaining gap.

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 limit, offset, and status are fully documented there, including the enum values. The description adds only what the schema already covers ('filter by status and paginate'). Baseline 3 is appropriate when the schema carries the parameter burden.

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 (list bulk verification jobs) with scope ('the account's'), ordering ('most recent first'), and returned fields (status, progress, summary). It is distinguishable from get_job_status/get_job_results by being the collection-level listing, though it never names those siblings 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?

Provides a purpose clause ('Use this to find past jobs and their job_ids'), which implies when to use it. However, it does not contrast with get_job_status, get_job_results, or how to drill into a specific job — the natural alternatives in this sibling set are left unnamed.

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