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

No annotations are provided, so the description must carry the full behavioral burden. It does not state that nothing is executed, whether the output is text or a file, any side effects, or permission requirements — all of which are especially important for a tool whose sibling actually runs 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?

Very short and front-loaded, which is good, but the single sentence is cryptic and the 'runner operator' parenthetical adds no usable information rather than earning its place.

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?

With no annotations, no output schema, and a trivial parameter schema, the description is the only source of information and it is inadequate: an agent cannot tell what the tool returns, whether anything executes, or why it should pick this over generate_and_execute_code.

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 100% for the single 'detail' parameter, so the schema already documents it. The description adds no meaning about what 'detail' should contain, so this sits at the baseline for fully-covered params.

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 phrase 'generate code only' implies a verb+resource and hints at the key distinction from the sibling generate_and_execute_code (generation without execution). However, it never explicitly says the code is returned rather than run, and the parenthetical 'code interpreter (runner operator)' muddies rather than clarifies the purpose.

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 explicit when-to-use or when-not guidance. The word 'only' faintly implies a contrast with generate_and_execute_code, but the agent must infer that comparison on its own; there is no stated condition for choosing this tool over its three siblings.

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