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. It implies no execution occurs, but says nothing about what is returned, whether the generated code is displayed, which language/runner is used, or any execution/safety constraints.

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?

It is a single short, front-loaded line with no waste, but the brevity is under-specification rather than genuine conciseness given the sibling ambiguity it needs to resolve.

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 that must be distinguished from generate_and_execute_code, with no output schema and no annotations, the description is far too thin. It leaves the agent unable to confidently decide between the two code-generation siblings.

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 100%, so the baseline is 3 per calibration, but the single parameter's schema description ("Specific parameters for this action.") is itself generic, and the tool description adds no meaning about what "detail" should contain.

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 states a verb+resource ("generate code") and the parenthetical "(runner operator)" hints at scope, and "only" implies no execution. However it never names the obvious alternative interpreter__generate_and_execute_code, so an agent must infer the distinction from the name alone.

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?

There is no explicit when-to-use guidance and no mention of alternatives, despite a sibling (interpreter__generate_and_execute_code) whose behavior overlaps almost entirely. The only signal is the word "only", which is left for the agent to interpret.

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