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

No annotations are provided, so the description carries the full burden. It discloses cost ($0.80/call via x402, USDC on Base), which is valuable beyond schema. However, it omits other key behavioral traits: output format, synchronicity, rate limits, and whether it invokes external workflows or merely generates text.

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?

Two short sentences, purpose front-loaded, no filler. The price sentence is relevant but the overall brevity leaves gaps that a slightly longer description could fill.

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?

Given no annotations, no output schema, and a crowded sibling set, the description is too sparse. It fails to explain what the assistant returns, how to structure the prompt, or how it differs from workflow_automation, leaving the agent under-informed for correct selection and 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% and the single 'prompt' parameter is fully documented in the schema. The description adds no additional meaning or format guidance for the prompt, so baseline 3 applies.

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?

States the domain ('Temporal workflow orchestration assistant') but not a specific action or output. The sibling 'workflow_automation' creates overlap, and the description does not differentiate or clarify what the assistant actually does with the prompt.

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 when-to-use guidance, no alternatives, no exclusions. The agent must infer usage solely from the name and price, which is insufficient given several sibling workflow-related tools.

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