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

Annotations already flag destructive=true, idempotentHint=false and openWorldHint=true; the description adds almost nothing beyond restating the name. It omits whether the change notifies the customer, whether it is reversible, whether custom statuses must pre-exist, and what happens on failure. For a declared-destructive mutation this is a real gap.

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 no waste, front-loaded with the action. It is concise but arguably under-specified rather than dense with useful information.

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?

A destructive, non-idempotent mutation with no output schema needs more than one sentence: what the response looks like, consequences of the status change, and any state preconditions are all absent.

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% and the status enum values are fully enumerated in the schema, so the description's mention of 'built-in or custom statuses' adds no new detail. Baseline 3 applies since 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?

Specific verb (set) plus resource (a job's status) and scope (built-in or custom statuses). Enough to distinguish from get_job/list_jobs/create_job, 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?

No indication of when to use this versus other job tools, no prerequisites (e.g., whether the job must exist or be in a particular state), and no mention of side effects or follow-up steps.

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