Agent Skills: codex-prompting

Prompt patterns and reusable system-prompt blocks for Codex-tuned GPT-5 models (e.g., gpt-5.3-codex / Codex CLI style). Use when you need to (1) build or tune an agentic coding harness prompt, (2) increase autonomy + persistence without premature stopping, (3) enforce disciplined editing + repo conventions, (4) improve tool usage/parallelism, apply_patch-first workflows, and safe git behavior in dirty worktrees, (5) reduce loggy/preamble noise while keeping useful progress updates, or (6) migrate an existing GPT-5-series prompt to Codex-style prompts.
