run_script

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

No annotations are provided, so the description carries the full behavioral burden. "From the top" adds one useful execution detail, but it does not disclose whether the call blocks, what happens if no script is stored, or how execution interacts with stop_script.

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 front-loaded sentence with no wasted words. The key action and starting point are stated immediately.

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?

The output schema can cover return values, and the zero-parameter schema is simple. However, for an action tool with no annotations, the description omits prerequisites, error behavior, and how it relates to upload_script or stop_script, leaving meaningful operational context missing.

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 tool has zero parameters and the schema is empty with 100% description coverage, so there are no parameter semantics to explain. Baseline 4 is appropriate for a parameterless tool.

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, "Start," and names the resource, "the stored script," plus scope, "from the top." It is clearly distinguishable from stop_script and script_status, though it does not explicitly name siblings or prerequisites.

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 implies the tool executes a stored script, but gives no when-to-use guidance, no when-not-to-use guidance, and no prerequisites such as whether upload_script must run first. The relationship to stop_script and script_status is left for the agent to infer.

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