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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description usefully adds that results are ordered newest-first and that each entry carries status and result links, which substitutes for the absent output schema. It says nothing about pagination (there is no cursor parameter, only a limit up to 50) or what happens when more jobs exist than the limit.

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 compact clause with no filler; ordering and payload are front-loaded. It is a sentence fragment rather than a full statement of the action, which slightly reduces clarity but costs nothing in length.

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 simple read-only listing tool this is close to adequate: no output schema exists and the description sketches the return shape. However, with three undocumented parameters and no mention of result-count limits or truncation behavior, an agent cannot confidently predict what it will get back when the account has many jobs.

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% across all three parameters, so the description needed to compensate and does not: it never mentions the kind filter, the status filter, or the limit. The enum values are largely self-explanatory, which softens the gap, but questions like whether the status filter interacts with the newest-first ordering, or whether limit silently truncates the result set, are unanswered.

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 names the resource ("The account's jobs"), the ordering ("newest first"), and the payload ("status and result links"), so an agent knows this is a collection read scoped to the account. It does not explicitly contrast itself with the singular sibling get_job, leaving the list-vs-single distinction to be inferred from the 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 statement of when to call this versus get_job, or versus the generate/create tools whose jobs these presumably are. No prerequisites, no guidance on whether filters should be used to narrow results. The agent is left to infer usage entirely from the tool name.

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