AGENTS.md

nextjs-migration-plugin AGENTS.md is an instructions file for Codex, OpenCode from Blazity/nextjs-migration-plugin. It costs 1,805 tokens per session, scanned A, original, MIT.

Project instructions for a Claude Code plugin that migrates public websites into Next.js applications. Next.js is a framework for building web applications, and the App Router is its newer page and routing system.

In plain words
What is it for?
Use them to discover, analyze, plan, extract, and build a Next.js migration from a website URL, optional source repository, and migration goal.
Why use it?
They define the migration stages, saved progress, shared-component discovery, build generation, and verification limits of the current pre-release version.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is Blazity/nextjs-migration-plugin's own configuration. It tells Codex and OpenCode how to work on nextjs-migration-plugin itself, so it is not a mod to install elsewhere.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nextjs-migration-plugin AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This file is the canonical prose-rules surface for AI agents working in this repository. Codex, Cursor, Windsurf, and VS Code Copilot read it natively; Claude Code reads it through the @AGENTS.md shim in CLAUDE.md.

Vision

nextjs-migration-plugin is a Claude Code plugin for migrating public websites into production-ready Next.js App Router projects. It turns a source URL, optional source repository, and migration goal into a phased, resumable workflow with persistent .migration/ state, shared component discovery, build generation, and verification gates.

Direction

The current product direction is a pre-release v1 focused on phases 1-5: discover, analyze, plan, extract, and build. Polish phases for visual parity, animation, performance, add-pages, library inspection, runs, and ship workflows are part of the approved design but are not all present in the current repository.

Repository Layout

Path What it is
plugin.json Claude Code plugin manifest, hard dependencies, hooks, command/skill/agent roots.
commands/ Thin slash-command wrappers for /migrate:* commands.
skills/ Project runtime skills, one directory per migration workflow.
agents/ Agent prompt templates used by migration phases.
lib/ TypeScript orchestration, loaders, schemas integration, state helpers, and phase runners.
schemas/ Zod schemas for adapters and migration state artifacts.
scripts/ Vendored extraction, crawl, validation, build, and visual tooling. Preserve vendor policy.
adapters/ Framework/CMS adapter JSON plus the generated schema template.
knowledge/ Shipped runtime knowledge loaded by plugin hooks and phase skills.
docs/ Canonical product docs: specs and ADRs.
.ai/ Shared AI harness: memory, plans, research, and vendored superpowers skills.
test/ and scripts/tests/ Vitest coverage for core library behavior and script helpers.

This is a single-package TypeScript repository using pnpm, Node.js, ESM, and Vitest. It is not a monorepo.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
