Evolve schemas without downtime: expand/contract (add -> backfill in batches -> switch -> drop) across separate deploys, lock-aware DDL (create indexes CONCURRENTLY, nullable-add-then-validate), reversibility, and ordered versioned migrations.
默认使用会先检查来源的 Prompt；你也可以切换为直接命令，或下载本地副本。
决定是否安装前，请先阅读 SKILL.md，以及 SkillsMP 当前展示的配套文件。
用 Codex 或 Claude 帮你安装 复制这段 Prompt，粘贴到 Codex、Claude 或其他助手里，让它检查 Skill 页面并帮你完成安装。
直接命令不会经过审查 Prompt；运行前请先检查来源。
npx skills add https://github.com/mcorbett51090/RavenClaude --skill safe-schema-migrations命令会保持在同一行。复制前请横向滚动并检查完整内容。

Route everyday, well-defined work (single-file edits, test-writing, summarization, mechanical refactors, boilerplate) to a cheaper coding agent (Grok or Copilot CLI) instead of doing it in the main Claude session, escalating multi-file/architecture/debugging/security work to Claude. Opt-in via the `cheap_lane:` comfort-posture knob.
Authors, validates and packages a claude.ai Organization Skill — the intake questions, the trigger and scope exercises, then lint, pack and verify against measured platform constraints. Reach for this when someone wants to publish a Skill to their organization, or when an upload was rejected and the reason is unclear.
Drafts a reply to an inbound customer email, grounded in the account record and the published help-centre articles rather than in recall. Use when a customer emails about billing, a renewal or an outage, when a reply must cite current policy, or when a teammate asks for a first draft to edit.

Add new (safely) -> backfill in batches -> dual-write/switch reads -> drop old. Across separate deploys. A rename = add-copy-switch-drop, not ALTER RENAME mid-traffic.
Volatile-default add, type change, or SET NOT NULL can lock the table. Use: nullable add + batched backfill + ADD CONSTRAINT ... NOT VALID then VALIDATE; create indexes CONCURRENTLY.
Every migration has a down path / tested rollback. Versioned, ordered, never edit a shipped migration. Sequence with devops-cicd/release-engineer.
