Rename the internal gpt-5-4-prompting skill to gpt-5-5-prompting and rewrite its guidance to match OpenAI's published GPT-5.5 prompt guidance and migration guide: - outcome-first prompts instead of process-heavy XML stacks - recommended skeleton (Role / Personality / Collaboration style / Goal / Success criteria / Constraints / Output / Stop rules) - re-evaluated reasoning effort defaults (5.5 needs fewer reasoning tokens at the same level; higher effort can cause overthinking) - what to delete when migrating a 5.4-era prompt - stopping conditions, retrieval budgets, validation defaults, and tool preambles - XML block library and recipes kept but demoted to opt-in modules Update references in agents/codex-rescue.md and skills/codex-cli-runtime/SKILL.md, and adjust tests.

Summary
Renames the internal
gpt-5-4-promptingskill togpt-5-5-promptingand rewrites its guidance to follow OpenAI's published GPT-5.5 prompt guidance and migration guide (developers.openai.com).Motivation
GPT-5.5 reasons more efficiently than GPT-5.4 and pays a real cost for noisy, process-heavy prompts. The current skill still teaches the GPT-5.4-era style (compact XML block stacks by default), which the GPT-5.5 docs explicitly recommend against — carrying a 5.4 prompt stack forward adds noise, narrows the model's search space, and pushes toward mechanical answers. This revives the direction of #301 (closed by its author as local-only) with content checked against the official docs.
