install_package

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only says 'Install a Python package using uv'. It does not mention side effects such as modifying the environment, requiring network access, or how conflicts are resolved. The mention of 'uv' adds a detail about the package manager but lacks consequential behavioral context.

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 that immediately communicates the tool's purpose. It contains no unnecessary words or fluff, making it highly concise and well-structured.

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 simple one-parameter tool, the description provides the core action and method, but it lacks usage guidelines and behavioral transparency. Given the absence of annotations, the description is not fully complete, though it covers the basics for a basic install operation.

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 input schema already fully describes the single parameter with 100% coverage, including an example ('pandas'). The description adds no additional semantic value beyond the schema, so the baseline of 3 is appropriate.

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 specific action ('Install') the resource ('a Python package') and the method ('using uv'). It distinguishes itself from sibling tools like execute_python and list_variables by indicating a package installation operation rather than code execution or variable inspection.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention situations such as needing to add a dependency, nor does it exclude using execute_python or list_variables for other tasks. The absence of any usage context or alternative comparisons leaves the agent without clear decision-making support.

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