Codex can generate tool-calling code on the fly — a new failure point for agent devs
srchvrs · x · 2026-09-09
- srchvrs shares a surprise discovery: don't assume agents will always call your tools (e.g., CLI) via pre-written code — in Codex at least, tool-calling code can be generated on the fly.
- This introduces an extra failure point: dynamically generated call code may diverge from expectations, so tool authors should design interfaces and error handling with this behavior in mind. Links to OpenAI's Programmatic Tool Calling docs.
