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

No annotations are provided, so the description must carry the behavioral burden, but it says nothing about what 'debug update existing code' actually does—whether it executes code, mutates files, persists changes, requires permissions, or has side effects.

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 short, but the brevity reflects under-specification rather than efficient communication. The single phrase is not front-loaded with actionable detail and contains no useful structure.

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 code-interpreter tool with no annotations, no output schema, and a near-empty parameter description, this definition is not complete enough for an agent to call it correctly or understand its consequences.

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 reported as 100%, which sets the baseline at 3 per the rubric. However, the sole parameter's schema description ('Specific parameters for this action') is itself vacuous, and the tool description adds no further meaning beyond the 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 restates the tool name almost verbatim ('debug update existing code') and adds only a generic parenthetical ('Code interpreter (runner operator)'). It does not specify the resource or distinguish this tool from siblings like interpreter__generate_and_execute_code or interpreter__generate_code_only.

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 is provided, no alternatives are named, and no conditions for selecting this tool over its siblings are given. Sibling tools are listed in context, but the description never references or contrasts them.

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