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

Beyond annotations that already mark this as destructive, non-idempotent, and open-world, the description adds critical operational caveats: starting respects approvals, failed or uncertain writes are never retried, and resume requires explicit user intent. It also warns that provider record text is untrusted data, which is important behavioral context for an agent.

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 front-loaded with the core action and then adds only relevant operational constraints, documentation pointers, and safety warnings. It is appropriately sized for a destructive workflow-control tool with no wasted sentences.

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?

It covers the key behavioral risks and usage constraints for a destructive workflow-control tool, and an output schema exists so return values need not be explained. The main gap is that jobId provenance and its relationship to sibling status/list tools are not clarified.

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 has 0% description coverage, so the description must compensate for two required parameters. It explains the action semantics reasonably well through the start/pause/resume/cancel prose, but it does not explain what jobId is, its format, or how to obtain it.

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 specific verbs and the exact resource: start, pause, resume, or cancel a saved workflow in this conversation. This clearly distinguishes it from creation, status, and generic write tools among the siblings.

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?

It gives clear usage conditions: only when requested by the user, resume only when the user explicitly says to continue, and uncertain outcomes require human reconciliation. It does not explicitly name alternative tools such as workflow_status, so it falls short of full when/when-not/alternatives guidance.

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