A set of rules for making visual or behavior changes directly in a Next.js application, a framework for building web apps with JavaScript or TypeScript.

Use it to adjust appearance or behavior in Next.js projects and prepare a consultation for engineers when deeper functional changes are needed.

It gives design-focused users a defined way to change the interface while limiting risky changes to the existing application.

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00017	$0.01052
Opus 5	$0.00009	$0.00526
Sonnet 5	$0.00003	$0.00210
Haiku 4.5	$0.00002	$0.00105

Measured 10d ago against content hash 5f9bf41b449c, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

design-mode 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 10d 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.

Design Mode

Design Mode is intended for users who excel in design rather than software development. It enables direct application design by editing Next.js code instead of using tools like Figma.

Avoid destructive changes.
Limit modifications to appearance or behavior only.
If functional changes or additions are necessary, create a consultation text for engineers and encourage the user to seek their input.

How to Start Design Mode

The step-by-step procedure below MUST be followed in order. Each step MUST be completed before proceeding to the next one. No steps should be skipped.

1. Check Requirements

All required tools must be verified in the following order:

Node.js Version Check
```
node -v
```
✅ REQUIRED: Version must be 22.14.0 or later ❌ If version requirement not met: See ./nodejs.mdc for installation instructions
pnpm Version Check
```
pnpm -v
```
✅ REQUIRED: Version must be 10.2.1 or later ❌ If version requirement not met: See ./nodejs.mdc for installation instructions
Vercel CLI Version Check
```
vercel --version
```
✅ REQUIRED: Version must be 41.6.0 or later ❌ If Vercel CLI is missing: Install with the command below
```
pnpm add -g vercel
```
Vercel CLI Login Status
```
vercel whoami
```
✅ REQUIRED: Must show a username ❌ If not logged in: See ./vercel-cli.mdc for login instructions
Vercel Project Link Check
```
[ -f .vercel/project.json ] && echo "Project is linked" || echo "We need to link vercel project"
```
✅ REQUIRED: Must show "Project is linked" ❌ If "We need to link vercel project" is displayed: a. List available teams: bash vercel team list b. Switch to team and list projects: bash vercel team switch [team-name] vercel project list c. Link the project: bash vercel link --yes --project [project-name]

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.

design-mode is a cursor rule published in the GitHub repository giselles-ai/giselle (555 stars, last pushed 8d ago), licensed Apache-2.0. It adds 17 tokens to every session and 1,052 once invoked, about $0.0001 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.
