codex_import

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

Annotations already declare readOnlyHint=true, and the description adds useful context: the actual write into the user library happens through document_preview and document_apply, not through codex_import itself. This clarifies the side-effect boundary and does not contradict the annotations.

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, front-loaded sentence with no filler. It efficiently conveys the main action and the downstream workflow, though it is a bit telegraphic.

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?

The workflow context and output schema help, but the missing meaning of the sole required parameter leaves the agent unable to invoke the tool correctly. For a one-parameter tool, omitting any explanation of that parameter is a critical completeness gap.

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 only parameter, id, has no schema description and the tool description never explains what id refers to. With 0% schema description coverage, the description needed to compensate, but it provides no semantic guidance for the sole required input.

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 a specific action: prepare a complete Skill or description as a standalone declaration. It gives the tool an identifiable role in the preview/apply workflow, though it does not explicitly differentiate it from siblings like document_import or document_preview.

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 by naming document_preview and document_apply as the downstream tools that write the draft into the user library. However, it does not explicitly state when to choose codex_import over alternative tools or what conditions make it the right choice.

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