codex-three-layer-delivery: Instructions file for Codex

AGENTS.md — Repository Maintainer Instructions

Purpose and Authority

This file governs maintenance of the codex-three-layer-delivery source repository itself. It is not a distributable project template and must not become a current-task status record.

• README.md is the authority for repository purpose, the three-layer model, supported adapters, and published layout.
• The English root is the canonical baseline. zh-CN/ is a translation pack; Claude and Cursor files are platform adapters that preserve documented platform differences.
• codex/global/AGENTS.md.template and rules/project/AGENTS.md.template are distributable templates. Do not make this maintainer file a byte-for-byte copy of either template.
• Detailed RD methods belong in the owning skills/rd-*/SKILL.md; this file keeps only repository-wide maintenance controls and pointers.

Before Editing

• Inspect the user request, effective instructions, target file, authoritative English source, maintained mirrors, nearby references, and relevant validator entry points before changing content.
• Reuse previously inspected stable project context only when its authoritative source, revision, and applicability remain known. Use applicable low-cost change detectors such as branch and HEAD, worktree status, changed paths, and relevant source revisions to scope refreshes.
• Re-read affected or decision-critical sources after revision changes, external edits, new evidence, context compaction, task redirection, or conflicting observations. Do not rescan the entire repository by default, and do not claim prior context remains current without checking applicable change detectors.
• For complex or high-impact maintenance, briefly identify the reused baseline and newly refreshed dynamic evidence at the first meaningful checkpoint when that improves reviewability; do not impose a fixed context-accounting format on simple tasks.
• Treat versions, installed tools, external releases, generated configuration, runtime state, and test results as dynamic evidence. Recheck them when they affect a conclusion; keep version snapshots in docs/compatibility.md, not in this file.
• This root AGENTS.md is the sole repository-maintainer authority. Files under rules/, codex/, zh-CN/, cursor/, and claude/ are distributable templates or adapters, not maintainer guidance. Keep instruction sources under non-discoverable .template filenames and Skills only in the shared skills/ and zh-CN/skills/ source trees. If an editor surfaces distributable sources as effective instructions, treat that as an unresolved adapter-isolation conflict: do not assume this root file overrides a more specific instruction, and record reproduced platform behavior in docs/compatibility.md rather than turning a single observation into a repository-wide runtime claim.
