m8811_set_list_step

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

The description discloses the readback behavior ('read back'), adding value beyond annotations which are all false. It does not detail side effects, error handling, or persistence, but for an instrument control tool the on-the-wire behavior is somewhat evident.

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?

A single sentence that is front-loaded with the verb and resource, with no wasted words. The sentence is well-structured and immediately informative.

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 no annotation support and an output schema present, the description covers the basic purpose but omits details like step indexing, units, or behavior on invalid input. It is adequate for a simple set/readback operation but not richly contextual.

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. It names 'voltage, current, or delay' which maps to voltage_v, current_a, and width_ms, giving semantic meaning. It does not explicitly map each parameter, nor discuss defaults, but the added context helps beyond bare schema.

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 clearly states the verb 'Set and read back' and the resource 'voltage, current, or delay for one LIST step', identifying a specific action on a specific object. It distinguishes from siblings like m8811_set_voltage or m8811_set_current by scoping to a single LIST step.

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?

Usage is implied: the description conveys that it targets one LIST step, so the agent understands it is for modifying a specific step's parameters. However, no explicit when-to-use vs alternatives are given, nor any exclusions.

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