product-design

product-design is a skill for Codex from evoelsewhere/evoflux. It costs 89 tokens per session (573 once invoked), scanned A, original, Apache-2.0.

A coordinated set of workflows for product and user-experience design. It covers research, design ideas, evidence-based reviews, prototype building, design checks, and handoff.

In plain words
What is it for?
Use it to research a product, design or rebuild an interface, create a prototype from a reference, review an experience, or prepare design work for handoff.
Why use it?
It provides a defined route for design tasks instead of treating every request as the same kind of work. It helps choose the relevant workflow and sequence for the requested deliverable.

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

product-design 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.

The scan reads SKILL.md. This mod also ships 2 executable files (references/workflows/user-context/scripts/init_user_context.py, references/workflows/user-context/scripts/user_context_preflight.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 34 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Product Design

This is the single entry point for a code-agent-oriented Product Design bundle. The original workflow instructions are under references/workflows/, with shared guidance under references/. The bundled React/Vite prototype template and package metadata are intentionally excluded.

Route the request

  1. Read references/workflows/index/SKILL.md completely. Treat it as the authoritative plugin-level scope, routing, sequencing, and browser-choice policy.
  2. Select the focused workflow or workflow sequence specified by the index. Read every selected workflow's SKILL.md completely before acting.
  3. Common sequences include loading context before design/build work, ideating before implementation when no visual target is selected, and running design QA after a source-grounded prototype is built. Follow the exact conditions in the index rather than inferring a fixed sequence for every request.
  4. Resolve relative links from the file that contains the link. Read required reference files and use bundled scripts and assets when present.
  5. Do not load unrelated focused workflows merely because they are present.

Bundled capabilities

Focused workflows live in references/workflows/: user-context, get-context, research, audit, ideate, url-to-code, image-to-code, design-qa, and share.

Shared reusable guidance lives in references/. Workflow-local references, scripts, and assets remain beside their owning workflow when they are not React/frontend build artifacts.

Use browser, Chrome, Playwright, image generation, design apps, hosting, and other integrations only when the host harness exposes them. The bundle's mention of a tool does not prove availability or authorization. Follow host permissions and the selected workflow's fallback behavior.

When creating a prototype, prefer the target repository's existing frontend stack. If there is no existing app and the user still wants a runnable web prototype, create the smallest suitable implementation using host-supported tools; React is not required. Do not look for the removed bundled prototype template or bootstrap script.

What ships with it

29 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
