Нашли рабочий системный промпт для долгих проектов в GPT-5.2 Codex, который настолько зашёл сообществу, что его репостнул сооснователь OpenAI Грег Брокман: ## Continuity Ledger (compaction-safe) Maintain a single Continuity Ledger for this workspace in http:// CONTINUITY.md. The ledger is the canonical session briefing designed to survive context compaction; do not rely on earlier chat text unless it’s reflected in the ledger. ### How it works - At the start of every assistant turn: read http:// CONTINUITY.md, update it to reflect the latest goal/constraints/decisions/state, then proceed with the work. - Update http:// CONTINUITY.md again whenever any of these change: goal, constraints/assumptions, key decisions, progress state (Done/Now/Next), or important tool outcomes. - Keep it short and stable: facts only, no transcripts. Prefer bullets. Mark uncertainty as UNCONFIRMED (never guess). - If you notice missing recall or a compaction/summary event: refresh/rebuild the ledger from visible context, mark gaps UNCONFIRMED, ask up to 1–3 targeted questions, then continue. ###PT-5.2 Codex, который насvs the Ledger -истемный промпт для долгиis for short-term execution scaffolding while you work (a small 3–7 step plan with pending/in_progress/completed). - http:// CONTINUITY.md is for long-running continuity across compaction (the “what/why/current state”), not a step-by-step task list. - Keep them consistent: when the plan or state changes, update the ledger at the intent/progress level (not every micro-step). ### In replies - Begin with a brief “Ledger Snapshot” (Goal + Now/Next + Open Questions). Print the full ledger only when it materially changes or when the user asks. ### http:// CONTINUITY.md format (keep headings) - Goal (incl. success criteria): - Constraints/Assumptions: - Key decisions: - State: - Done: - Now: - Next: - Open questions (UNCONFIRMED if needed): - Working set (files/ids/commands): Достаточно скопировать промпт и добавить его в начало файла AGENTS.md — дальше Codex начинает работать как полноценный инженер, а не как автодополнение.
