eval

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

No annotations are provided, so the description must fully disclose behavioral traits. It only describes the return format (success/error dict) but does not warn about potential side effects, risks of arbitrary code execution, or required permissions. This is a significant gap for an evaluation tool.

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 structured with 'Args' and 'Returns' sections, but includes redundant formatting (e.g., 'Returns:' block) that could be more concise. It is not overly long but could be streamlined.

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?

Given that this is an arbitrary code execution tool with no annotations, the description lacks crucial information about side effects, safety considerations, error behavior, and prerequisites. It mentions the return format but omits important context for safe usage.

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 coverage is 100% with a single 'code' parameter described. The description repeats the same text as the schema's description, adding no additional meaning beyond what is already in the input schema. Baseline score 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 'Evaluate a Pharo Smalltalk expression' with a specific verb and resource. It distinguishes from sibling tools that perform different operations like export, import, reading, or searching.

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 purpose is implied by the tool name and description, but there is no explicit guidance on when to use this tool versus alternatives or any exclusions. Sibling tools cover different domains, but no when-not advice is provided.

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