product-proof-saas is a skill for Codex from devinilabs/pro-skill. It costs 63 tokens per session (886 once invoked), scanned A, a copy of product-proof-saas, MIT.

A landing-page approach for SaaS and AI products that uses a real workflow or interface as evidence of how the product works. It explains the path from input through processing, editing, approval, and publishing.

In plain words
What is it for?
It helps create or redesign product pages with interface-led heroes, sample workflows, audience sections, feature modules, pricing comparisons, and FAQ handoffs.
Why use it?
Marketing claims are easier to judge when visitors can see the product mechanism and a clearly labelled example. The structure also addresses audiences, pricing limits, objections, and common questions.

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-proof-saas 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.

How it starts

The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Product Proof SaaS

Show the product mechanism before making broad claims. Make the interface the evidence, not decoration.

Establish the Story

  1. Name the user friction in one sentence.
  2. Put a real, deterministic, or clearly labeled sample workflow in the hero.
  3. Explain the mechanism as input, processing, draft, edit, approval, and publish states.
  4. Organize features around user outcomes and audiences.
  5. Keep pricing limits and objections in one continuous decision path.

Replace source brands, outputs, customers, metrics, prices, screenshots, and claims. Never fake generation speed or output quality.

Build the Visual System

  • Use white-to-pale-blue surfaces, near-black text, soft gray grid lines, and one cool signal color.
  • Pair a high-x-height grotesk with compact mono labels.
  • Use 12-column product grids, 12–16px radii, thin borders, and honest UI screenshots.
  • Keep product panels denser than the marketing copy around them.
  • Use black primary actions and reserve the signal color for active state, progress, selection, and focus.
  • Avoid decorative AI particles, constant floating, and vague glowing orbs.

Compose the Page

  • Header: keep product routes compact and the primary trial or demo action obvious.
  • Hero: pair the value proposition with a product stage that demonstrates one complete outcome.
  • Friction proof: show a before/after, time breakdown, or concrete workflow constraint.
  • Feature modules: use small icons and focused copy around real capabilities.
  • Workflow: explain state changes and human control, not a magical one-click promise.
  • Audience tabs: preserve content in the DOM and deep-link when useful.
  • Proof: use verified examples, customer evidence, or clearly labeled samples.
  • Pricing: align comparable limits, usage units, and footnotes.
  • FAQ: deep-link ambiguous plan terms from the comparison table.
  • Footer: resolve trust, documentation, and legal routes against a pale-blue fade.

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.
