Create Codex Terminal From Agent

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

No annotations are provided, so the description carries the full burden. It discloses the fallback behavior for sourceNodeId but does not mention side effects, required permissions, or what 'connected' means. It adds some value beyond the schema but lacks rich behavioral context.

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?

Two short sentences that front-load the primary purpose. Every word earns its place; no redundancy or filler.

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 4 parameters, no output schema, and no annotations, the description provides too little context. It does not explain what a Codex terminal is, how agentPresetId works, or the effects of cwd and addToGrid. Sibling tools exist but no guidance on selection.

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%, so parameters are fully undocumented. The description only explains sourceNodeId's default behavior. No information is given about agentPresetId, cwd, or addToGrid, leaving the agent to infer their meanings from names alone.

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 verb ('Create'), resource ('Codex terminal'), and method ('using an agent preset'). It also mentions the default behavior for sourceNodeId, helping distinguish from siblings like 'create_claude_terminal_from_agent' and 'create_connected_terminal'.

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 context (creating a connected Codex terminal with an agent preset) but provides no explicit guidance on when to use this tool versus siblings, nor when not to use it. No alternatives are mentioned.

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