Maintain a CHANGELOG.md following the Keep a Changelog standard. Use after commits, on /commit, when the user asks to update the changelog, or when releasing a version — maps conventional-commit types to Added/Changed/Fixed/Security categories. Archives old releases into per-major files (changelog/CHANGELOG-1.x.md) so the main file stays small no matter how many versions accumulate.

codex-cli

georgekhananaev/claude-skills-vault

Run OpenAI Codex CLI for coding tasks and second-opinion audits. Use when a user asks to run/ask/use Codex, says "codex prompt", or wants Claude to delegate a logic/code review to OpenAI models. Covers direct `codex` CLI invocation (exec, review, resume, apply, doctor, mcp), the six reasoning-effort levels (none/minimal/low/medium/high/xhigh), sandbox + dangerous flags, background execution, rate-limit safety, and when to defer to the official OpenAI Codex Claude Code plugin (`codex:rescue`) instead. Preflights with `codex doctor` to read the current default model + surface available updates; never hardcodes model/effort, letting Codex pick its own current best default unless the user explicitly names one.

Upgrade Next.js

Upgrade the current project to the latest Next.js version following official migration guides.

Instructions

Detect current version: Read package.json to identify the current Next.js version and related dependencies (React, React DOM, etc.)

Fetch the latest upgrade guide: Use WebFetch to get the official upgrade documentation:

Codemods: https://nextjs.org/docs/app/guides/upgrading/codemods
Version-specific guides (adjust version as needed):
- https://nextjs.org/docs/app/guides/upgrading/version-16
- https://nextjs.org/docs/app/guides/upgrading/version-15

Determine upgrade path: Based on current version, identify which migration steps apply. For major version jumps, upgrade incrementally (e.g., 13 → 14 → 15 → 16).

Prefer the automated path first: the official upgrade codemod bumps deps AND runs the right transforms interactively:

npx @next/codemod@latest upgrade latest   # or: upgrade patch|minor|major|<version>
next upgrade                              # built-in self-upgrade command (Next 16.1+)

Fall back to individual codemods when the automated path can't run:

npx @next/codemod@latest <transform> <path>

Common transforms:

next-async-request-api - Updates async Request APIs (v15)
next-request-geo-ip - Migrates geo/ip properties (v15)
next-dynamic-access-named-export - Transforms dynamic imports (v15)
remove-experimental-ppr / remove-unstable-prefix - PPR & unstable_* cleanup (v16)
middleware-to-proxy - middleware.ts → proxy.ts (v16)
next-lint-to-eslint-cli - migrate off next lint (v16)

Update dependencies: Upgrade Next.js and peer dependencies together:

npm install next@latest react@latest react-dom@latest

Review breaking changes: Check the upgrade guide for manual changes needed:

API changes (e.g., async params in v15)
Configuration changes in next.config.js
Deprecated features being removed

Update TypeScript types (if applicable):

npm install @types/react@latest @types/react-dom@latest

Test the upgrade:

ASK the user before running npm run build (builds are slow; some users forbid unprompted builds)
Run npm run dev and test key functionality
