Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01839 | $0.01839 |
| Opus 5 | $0.00920 | $0.00920 |
| Sonnet 5 | $0.00368 | $0.00368 |
| Haiku 4.5 | $0.00184 | $0.00184 |
Grade A, and why
nextarter-tailwind 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Next.js: ALWAYS read docs before coding
Before any Next.js work, find and read the relevant doc in node_modules/next/dist/docs/. Your training data is outdated — the docs are the source of truth.
AI Agent Guidance: nextarter-tailwind
This file provides context and instructions for AI agents (Cursor, Antigravity, Zed, Windsurf) to effectively navigate and modify this repository.
1. Mental Model for Agents
Implementation Delegation
The most important pattern to understand is that src/app is just a shell.
- To modify a page's content, look in
src/lib/pages/[page-name]. - To modify the site-wide layout, look in
src/lib/layout. - Do NOT add heavy logic or massive JSX blocks directly into
src/app.
Tooling Strategy
- Linter: We use Biome. Do not suggest adding ESLint or Prettier config.
- Package Manager: pnpm. Use
pnpmfor all commands. - Styles: Tailwind CSS v4. Use standard utility classes.
2. Module Blueprint
| Directory | Content Type | Change Frequency | Risk Level |
|---|---|---|---|
src/app |
Routing/Next.js glue | Low | High (Affects routing) |
src/lib/pages |
Feature implementation | High | Low |
src/lib/layout |
Shared UI shell | Medium | Medium |
src/lib/components |
Atomic components | Medium | Low |
src/lib/styles |
Design System/Global CSS | Low | High |
3. Recommended Prompts for LLMs
- Adding a Page: "I want to add a new page
/about. Create a new directorysrc/lib/pages/about, implement the component there, and then createsrc/app/about/page.tsxthat exports it." - Adding a Shared Component: "Create a new atomic component
Buttoninsrc/lib/components/button.tsx. Follow the kebab-case naming convention and use named exports." - Refactoring Styles: "Review the Tailwind classes in
src/lib/pages/home/index.tsxand suggest optimizations or consistency improvements based on the existing design tokens inglobals.css."
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.

nextarter-tailwind AGENTS.md is an instructions file published in the GitHub repository agustinusnathaniel/nextarter-tailwind (125 stars, last pushed 3d ago), licensed MIT. It adds 1,839 tokens to every session, about $0.0092 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
