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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so safety is covered. The description adds one genuine behavioral fact beyond them: results are ordered newest first and limited to 'recent' jobs. It does not disclose the default limit, whether 'recent' is a fixed window, or any pagination behavior, so it remains thin.

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?

A single short sentence with the scoping and ordering information front-loaded and no filler. It is efficiently sized, though as a noun fragment it is arguably under-specified rather than concise.

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?

With no output schema, an undocumented parameter, and twelve sibling tools, the description should carry more weight than one clause. It omits result count defaults, recency window, and any routing to get_job or the other list_* tools.

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 0% and the single 'limit' parameter (1-50) is never mentioned in the description, so the agent gets no explanation of what the limit controls or what the default is. The description does not compensate for the schema gap.

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 fragment 'The account's recent jobs, newest first' identifies the resource and its scope/ordering, but never states a verb or that this is a listing operation with a bounded result set. Against siblings like get_job, list_monitors and list_pipelines it hints at a collection read but does not clearly differentiate itself beyond the tool name.

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?

There is no when-to-use guidance, no mention of the sibling get_job for a single job, and no statement of when listing is preferable to get_job_results or get_events. The agent must infer all routing from the tool name alone.

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