time_expression

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

With no annotations, the description carries full burden. It states the tool times and tracks memory, but does not disclose side effects (e.g., whether it leaves state unchanged), or what happens to the expression after timing. The behavioral context is minimal.

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, concise sentence that front-loads the action. It is efficient but could be slightly more structured to separate the timing and memory aspects. No unnecessary words.

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 the single required param and presence of an output schema, the description is somewhat complete. However, it lacks details on the output format, what 'memory tracking' entails, and the exact behavior. There is room for improvement.

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%, and the tool description does not add meaning to the 'expression' parameter beyond its name and type. It does not clarify what kind of expressions are accepted (e.g., Mathematica code, strings, etc.).

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 tool times the evaluation of an expression with memory tracking. The verb 'time' and resource 'expression' are specific, and it distinguishes itself from sibling tools like 'execute_code' or 'evaluate_cell' by adding timing and memory tracking.

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 implies usage when timing and memory tracking are needed, but does not explicitly tell when to use it versus alternatives like 'evaluate_cell' or 'trace_evaluation'. No when-not-to-use guidance is provided.

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