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

The annotations are all false and provide little positive safety information, so the description carries the burden. It discloses key behavior: the user does not keep anything running, notifications only fire when results change, a workspace token is needed for later management, and capacity limits apply. This goes well beyond the schema.

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 a dense paragraph but front-loads the core behavior and organizes kinds clearly. The cost/subsidy sentence is peripheral but brief and useful context, so the length is justified without being bloated.

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 an output schema present, return-value detail is not required. The description plus schema covers parameters, prerequisites, scheduling behavior, and notification semantics. A minor gap is that pipeline input is only implied through a reference to create_pipeline, but the overall picture is still sufficient for correct invocation.

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%, so the baseline is 3. The description adds real meaning by explaining each kind, clarifying the input as a URL or research question, and explaining when notify_url matters. It does not fully elaborate the pipeline input, but the schema plus create_pipeline reference cover most needs.

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 uses a specific verb ('Create') and a clearly named resource ('a task that runs on a schedule in our cloud'), then enumerates the four supported kinds. This leaves no doubt that this is the creation tool among siblings like delete_task, list_tasks, and get_task_runs.

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 clear usage context: use this when you want a background scheduled task, especially change-triggered watching or recurring research, and it calls out the workspace-token prerequisite. It does not explicitly enumerate when-not-to-use cases, but the four kinds and the cloud-scheduled framing make the intended use clear.

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