Codex Prompt Anti-Patterns

Avoid these when prompting Codex or GPT-5.4.

Vague task framing

Bad:

Take a look at this and let me know what you think.

Better:

<task>
Review this change for material correctness and regression risks.
</task>

Missing output contract

Bad:

Investigate and report back.

Better:

<structured_output_contract>
Return:
1. root cause
2. evidence
3. smallest safe next step
</structured_output_contract>

No follow-through default

Bad:

Debug this failure.

Better:

<default_follow_through_policy>
Keep going until you have enough evidence to identify the root cause confidently.
</default_follow_through_policy>

Asking for more reasoning instead of a better contract

Bad:

Think harder and be very smart.

Better:

<verification_loop>
Before finalizing, verify that the answer matches the observed evidence and task requirements.
</verification_loop>

Mixing unrelated jobs into one run

Bad:

Review this diff, fix the bug you find, update the docs, and suggest a roadmap.

Better:

  • Run review first.
  • Run a separate fix prompt if needed.
  • Use a third run for docs or roadmap work.

Unsupported certainty

Bad:

Tell me exactly why production failed.

Better:

<grounding_rules>
Ground every claim in the provided context or tool outputs.
If a point is an inference, label it clearly.
</grounding_rules>
