Codex Debug: Bug Investigation

This is a reusable natural-language prompt for Codex, not a shell command. Work in the repository at [REPOSITORY_OR_PATH]. Goal: reproduce and isolate a reported defect. Context: [CONTEXT]. Constraints: [CONSTRAINTS]. Definition of done: [ACCEPTANCE_CRITERIA]. Reproduce first, gather evidence, rank hypotheses, and change code only after identifying the likely cause. Read applicable AGENTS.md guidance and use Codex’s inspection, editing, and verification workflow; keep approval boundaries and the user’s working tree intact. First read the repository instructions and relevant framework documentation. Preserve unrelated user changes. State assumptions, cite files and lines for findings, and ask only when a missing decision would materially change the result. Do not invent APIs, commands, flags, test results, or file contents. Deliver: reproduction, hypotheses, root cause, and minimal fix. Run the repository’s relevant formatting, lint, type, test, and build checks when authorized, and report exact results.
