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

The description adds substantial behavioral context beyond the annotations: it requires an expectedVersion fence, requires current resolved-action authorization, preserves the confirmed manifest, and retries only eligible unfinished transient work. These details are valuable for a mutating operation with destructiveHint=true. The remaining gap is that it does not explain failure behavior or what exactly is destructive.

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 three dense sentences with no obvious filler, and the exclusion is placed last as a boundary clarification. It could be more front-loaded by naming the resume action directly. The jargon is compact but appropriate for an operator-facing tool.

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 two-parameter mutating tool with annotations and an output schema, the description covers authorization, concurrency fencing, scope preservation, retry scope, and one key exclusion. It is not fully complete because the expectedVersion semantics and the precise when-to-use conditions remain underspecified. Still, it gives enough context to call the tool correctly in most cases.

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 schema documents jobId but leaves expectedVersion without a schema description. The description compensates partially by calling expectedVersion a mandatory fence, which signals its concurrency-control role, but it does not explain how the expected version is obtained or what a mismatch means. With 50% schema coverage, this is adequate but incomplete.

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 identifies the resource as bulk-job work and describes the operation as controlling remaining work by keeping the confirmed manifest and retrying unfinished transient work. It also distinguishes the tool from schedules_resume by explicitly saying it does not resume selected schedules. The verb 'controls' is less precise than 'resumes', but the behavior is clear enough in context.

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?

The description gives one useful boundary: it does not resume selected schedules, which helps route away from schedules_resume. However, it does not explicitly state when to use this tool instead of sibling bulk operations like bulk_pause, bulk_cancel, or bulk_confirm. Usage is therefore implied rather than fully guided.

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