python_file

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

With no annotations, the description carries the full burden of disclosure. It only states that it executes a file and returns output, omitting critical information about potential side effects, sandboxing, working directory, error handling, or security implications of running arbitrary code.

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 one sentence and front-loaded, making it easy to scan. However, the phrase 'This function will' is filler; a more direct phrasing like 'Executes a Python file and returns output' would be tighter. The conciseness is good but not maximal.

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 executes arbitrary code, the description is severely under-specified. It lacks details about the execution environment, return format, error behavior, and access to system resources. Given the high-risk nature and absence of annotations or output schema, the description is insufficient for safe and correct use.

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 schema has one required string parameter 'file' with no description. The description adds that it is a Python file, implying it is a path, but does not clarify whether it accepts absolute/relative paths or file content. It provides minimal additional 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 clearly identifies the action (execute) and resource (a python file) and mentions returning output. However, it does not differentiate from the sibling tool python_code, which also executes Python, but the purpose itself is unambiguous.

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 over alternatives like bash or python_code. The description does not mention use cases, prerequisites, or exclusions, leaving the agent without contextual decision-making information.

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