Prompt Blocks

Use these blocks selectively when composing Codex or GPT-5.4 prompts. Wrap each block in the XML tag shown in its heading.

Core Wrapper

task

Use in nearly every prompt.

<task>
Describe the concrete job, the relevant repository or failure context, and the expected end state.
</task>

Output and Format

structured_output_contract

Use when the response shape matters.

<structured_output_contract>
Return exactly the requested output shape and nothing else.
Keep the answer compact.
Put the highest-value findings or decisions first.
</structured_output_contract>

compact_output_contract

Use when you want concise prose instead of a schema.

<compact_output_contract>
Keep the final answer compact and structured.
Do not include long scene-setting or repeated recap.
</compact_output_contract>

Follow-through and Completion

default_follow_through_policy

Use when Codex should act without asking routine questions.

<default_follow_through_policy>
Default to the most reasonable low-risk interpretation and keep going.
Only stop to ask questions when a missing detail changes correctness, safety, or an irreversible action.
</default_follow_through_policy>

completeness_contract

Use for debugging, implementation, or any multi-step task that should not stop early.

<completeness_contract>
Resolve the task fully before stopping.
Do not stop at the first plausible answer.
Check whether there are follow-on fixes, edge cases, or cleanup needed for a correct result.
</completeness_contract>

verification_loop

Use when correctness matters.

<verification_loop>
Before finalizing, verify the result against the task requirements and the changed files or tool outputs.
If a check fails, revise the answer instead of reporting the first draft.
</verification_loop>

Grounding and Missing Context

missing_context_gating

Use when Codex might otherwise guess.

<missing_context_gating>
Do not guess missing repository facts.
If required context is absent, retrieve it with tools or state exactly what remains unknown.
</missing_context_gating>

grounding_rules

Use for review, research, or root-cause analysis.

<grounding_rules>
Ground every claim in the provided context or your tool outputs.
Do not present inferences as facts.
If a point is a hypothesis, label it clearly.
</grounding_rules>

citation_rules

Use when external research or quotes matter.

<citation_rules>
Back important claims with citations or explicit references to the source material you inspected.
Prefer primary sources.
</citation_rules>

Safety and Scope

action_safety

Use for write-capable or potentially broad tasks.

<action_safety>
Keep changes tightly scoped to the stated task.
Avoid unrelated refactors, renames, or cleanup unless they are required for correctness.
Call out any risky or irreversible action before taking it.
</action_safety>

tool_persistence_rules

Use for long-running tool-heavy tasks.

<tool_persistence_rules>
Keep using tools until you have enough evidence to finish the task confidently.
Do not abandon the workflow after a partial read when another targeted check would change the answer.
</tool_persistence_rules>

Task-Specific Blocks

research_mode

Use for exploration, comparisons, or recommendations.

<research_mode>
Separate observed facts, reasoned inferences, and open questions.
Prefer breadth first, then go deeper only where the evidence changes the recommendation.
</research_mode>

dig_deeper_nudge

Use for review and adversarial inspection.

<dig_deeper_nudge>
After you find the first plausible issue, check for second-order failures, empty-state behavior, retries, stale state, and rollback paths before you finalize.
</dig_deeper_nudge>

progress_updates

Use when the run may take a while.

<progress_updates>
If you provide progress updates, keep them brief and outcome-based.
Mention only major phase changes or blockers.
</progress_updates>
