execute

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says the tool delegates to Codex CLI and returns a structured report, without explaining potential filesystem modifications, the meaning of sandbox modes, or safety implications. The sandbox parameter hints at risk but is not elaborated.

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 front-loaded with a single clear purpose sentence followed by a compact, well-organized Args list. Every line provides useful information with no wasted 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 tool's potentially dangerous ability to execute tasks and the presence of several sibling tools, the description lacks usage context and safety notes. However, an output schema exists and the parameter list is complete, making the description minimally viable for basic invocation.

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 schema has no property descriptions (0% coverage), but the description's Args section provides meaningful one-line explanations for all five parameters, including the allowed sandbox values and the default behavior of cwd. This compensates well for the missing schema descriptions, though the explanations are terse.

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 states 'Codex CLI(GPT-5.4)にタスクを委譲' (delegate tasks to Codex CLI) and notes that it returns a structured report, giving a clear verb and resource. However, it does not differentiate this tool from sibling tools like parallel_execute or spawn_codex_agent.

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?

There is no guidance on when to use execute versus alternatives such as parallel_execute, trace_execute, or the codex agent tools. The description only lists parameters and provides no context for tool selection.

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