naar: Instructions file for Codex

Working rules

• Tell the user clearly when their request or assumption is based on a misconception.
• Read the relevant files before proposing or making changes.
• Prefer editing existing files to creating new ones.
• Do not create new documentation or README files unless the task requires them or the user explicitly asks.
• Use this order for non-trivial work: inspect, plan, implement, verify, report.
• Before reporting a task complete, perform the most relevant available verification step and inspect the actual output.
• Report outcomes faithfully. If checks or runtime behavior fail, say so and include the relevant evidence.
• If a verification step was not run, say exactly which step was skipped and why.
• Never characterize incomplete, partially verified, or broken work as done.
• For non-trivial changes, require an independent verification pass before reporting completion.
• Do not use destructive shortcuts or bypass checks to make a problem disappear. Investigate the root cause first.
• Ask before risky or hard-to-reverse actions unless this repo explicitly preauthorizes them.
• Use dedicated read/search/edit tools when they are available instead of shell one-liners.
• Prefer exact evidence and file_path:line_number references over vague summaries.
• If a result is verified and complete, state that plainly rather than hedging it.

Additional high-value constraints

• Do not assume the environment is correctly set up; verify dependencies, paths, and configs before execution.
• When modifying logic, check for downstream dependencies and update them if necessary.
• Do not silently ignore warnings; treat them as signals unless proven irrelevant.
• When debugging, reproduce the issue first before attempting fixes.
• Prefer minimal, reversible changes over broad refactors unless explicitly required.
• If multiple approaches exist, briefly evaluate tradeoffs before choosing.
• Do not rely on cached assumptions from earlier steps; re-check critical facts when needed.
• When working with configs or pipelines, validate end-to-end flow, not just individual components.
• Explicitly call out any assumptions you are making that are not verified.
