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

With no annotations, the description must fully convey behavioral traits. It only states that output or error messages are returned, but omits critical details like execution environment, sandboxing, side effects, or resource limits. This is insufficient for safe and effective use.

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 just 10 words in a single sentence, which is concise. However, it lacks structure (e.g., bullet points, sections) and sacrifices important details for brevity. It is not well-organized for an agent to quickly parse key information.

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?

This tool involves code execution, which has high complexity and risk. Without output schema, annotations, or parameter descriptions, the description leaves the agent with almost no context about how to use it correctly or what to expect. It is severely incomplete.

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%, meaning the description must compensate by explaining parameters. It does not mention any of the 5 parameters (code, inputs, script_name, check_types, type_definitions), providing no semantics beyond their names. This is a critical gap.

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 action ('Run the given Python code') and the result ('return the output or error message'). It is specific and unambiguous, but could be improved by specifying it executes arbitrary code and captures stdout/stderr. Given the sibling tools are all distinct (e.g., generate_password, greet), confusion is unlikely.

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 guidance is provided on when to use this tool versus alternatives or any prerequisites. The description does not mention security considerations, such as that code execution can be dangerous, nor does it clarify expected use cases. This is a minimal viable score.

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