A set of rules for an AI product design workflow with six commands, from creating a project through writing requirements, wireframes, visual design, and a prototype. Each stage uses outputs from the earlier stages.

Use it to set up the /new-project, /prd, /lofi, /midfi, /hifi, and /ui-proto workflow and keep their documents and application files organised.

It gives design work a defined order and shared file locations instead of leaving each step disconnected. It also identifies which role and command handle each stage.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/luiscielak/ai-product-design-rules

Made for: Cursor.

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	$0.01078	$0.01078
Opus 5.5	$0.00431	$0.00431
Sonnet 5.5	$0.00216	$0.00216
Haiku 4.5	$0.00108	$0.00108

Security

Grade A, and why

00-workflow 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 5d 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.

AI product design workflow

Workflow overview

These rules define a structured AI product design workflow with six sequential stages:

Project Setup (/new-project) → 2. PRD (/prd) → 3. Lo-Fi Wireframes (/lofi) → 4. Mid-Fi Wireframes (/midfi) → 5. Hi-Fi Design (/hifi) → 6. Prototype (/ui-proto)

Each stage builds on the previous one. When a command is invoked, check for prerequisite outputs and reference them.

Commands and rule files

When the user types one of these commands, read the matching rule file and follow it.

Command	Role	Rule file	Writes to
`/new-project`	Project Manager	`.cursor/rules/01-new-project.mdc`	`projects/{project_name}/`
`/prd`	Product Owner	`.cursor/rules/02-prd.mdc`	`docs/PRD.md`
`/lofi`	UX Designer	`.cursor/rules/03-lofi.mdc`	`design/wireframes/lofi/`
`/midfi`	Product Designer	`.cursor/rules/04-midfi.mdc`	`design/wireframes/midfi/`
`/hifi`	UI Designer	`.cursor/rules/05-hifi.mdc`	`design/ui-design/`
`/ui-proto`	UI Engineer	`.cursor/rules/06-ui-proto.mdc`	`app/`

Paths in the "Writes to" column are relative to projects/{project_name}/.

Project layout

├── app/                      # Prototype (Next.js by default)

docs/ holds written documents (brief, PRD, presentations). design/ holds design artifacts (wireframes, UI kit).

General guidelines (apply to all commands)

Working directory context

When working within a project directory (projects/{project_name}/), use relative paths:
- docs/PRD.md (not projects/{project_name}/docs/PRD.md)
- design/wireframes/lofi/ (not projects/{project_name}/design/wireframes/lofi/)
- design/ui-design/ (not projects/{project_name}/design/ui-design/)
- app/ (not projects/{project_name}/app/)
Detect current working directory and adjust paths accordingly
If unsure, check if docs/, design/, or app/ directories exist in current location

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.

00-workflow is a cursor rule published in the GitHub repository luiscielak/ai-product-design-rules (4 stars, last pushed 5d ago), licensed MIT. It adds 1,078 tokens to every session, about $0.0043 per session on Opus 5.5. 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 2026-10-28.
