What problem does it solve? Writing effective prompts for Codex GPT-5.6 delegation is error-prone: vague tasks, missing output contracts, and absent verification rules lead to incomplete fixes, unsupported claims, and stalled runs. This Skill provides a disciplined, block-based prompting method so every delegated implementation, debugging, or fix-cycle task produces usable results. ## Core Features & Use Cases - Reusable XML prompt blocks: Standardized tags like <task>, <structured_output_contract>, <verification_loop>, and <grounding_rules> give prompts stable internal structure. - Ready-made recipes: End-to-end templates for diagnosis, narrow fixes, root-cause review, research, and prompt-patching tasks. - Anti-pattern guidance: Concrete before/after examples showing how to fix vague framing, missing output contracts, and unsupported certainty. - Use Case: When the supercodex orchestrator delegates a bug fix to Codex, it assembles a prompt with <task>, <completeness_contract>, <verification_loop>, and <action_safety> so Codex applies a scoped, verified fix without stopping early or refactoring unrelated code. ## Quick Start Ask the orchestrator to compose a Codex GPT-5.6 prompt for a debugging task using the diagnosis recipe with verification and grounding blocks.
