import_package

Import a Pharo package from a specified file path. Provide the package name and optional path to load it into the environment.

Instructions

Args: package_name: The name of the package to import path: The path to the package file to import (default: /tmp)

Returns: dict: API response with success/error and result - Success: {"success": True, "result": str} - result contains import success message - Error: {"success": False, "error": str} - error contains error message

Behavior3/5

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

Without annotations, the description provides basic behavioral info (imports package, returns success/error dict) but does not disclose side effects, permissions, or limitations (e.g., overwrite behavior).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is structured with Args/Returns sections and is relatively concise, though it repeats schema information slightly, which could be trimmed.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the core functionality and return format, but for a state-modifying tool, it lacks details on edge cases (e.g., path requirements, existing package conflicts).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the description restates parameter names and descriptions, adding minimal new semantic value beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'import' and the resource 'a package from specified path', distinguishing it from siblings like 'export_package' and 'list_packages'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use (when importing a package) but does not explicitly state when to use it over alternatives or any prerequisites. Lacks direct guidance.

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