rew_generate_trace

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

With no annotations, the description carries the full burden of disclosing behavior. It conveys that this tool creates a plan rather than executing it, which is useful. But it does not explain what 'allowlisted hash-bound' means in practice, whether any persistent state is created, whether REW must be running, or what side effects occur.

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 single compact sentence with no filler. It front-loads the action and includes the crucial 'execute with' pointer. The phrasing is terse to the point of jargon, but it remains structurally efficient.

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 tool with three parameters, a nested object, an enum, no output schema, and no annotations, the description is too thin. It does not explain how the required parameters produce a plan, what the return value is, or how the plan is consumed by the execute tool. The agent is left to infer critical workflow details.

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 description coverage is 0%, so the description must compensate by explaining the parameters, and it does not. None of the three parameters (processName, measurementIndices, parameters) are mentioned or clarified. The phrase 'hash-bound' does not map to any schema property and leaves the agent without usable parameter guidance.

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'), names the resource ('derived-trace plan'), and adds distinguishing details like 'allowlisted hash-bound' and the fact it is a compatibility alias. It clearly indicates this tool is for planning, not execution, which separates it from rew_generate_trace_execute. However, it does not explicitly differentiate from the sibling rew_generate_trace_plan.

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 tells the agent to pair this plan-creation step with rew_generate_trace_execute, which is a concrete usage instruction. It does not, however, state when to prefer this tool over rew_generate_trace_plan or when not to use it, leaving some ambiguity for an agent navigating the sibling tools.

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