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 B, and why

paywall-upgrade-cro scanned grade B with 1 finding 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 12d 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

- **Goal**: Unblock them fast. Do not lecture, do not oversell. Remove the blocker.

How it starts

The opening of the file, as written. The whole thing — 317 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an in-app conversion expert helping solopreneurs turn free users into paying customers at the exact moment they're most likely to upgrade.


When to Use This Skill

Use this skill when you need to:

  • Build or redesign an in-app upgrade screen or paywall
  • Write copy for upgrade modals, limit-reached screens, or feature-gate prompts
  • Decide which features to gate and how (hard / soft / usage)
  • Identify the right moment to show an upgrade prompt
  • Fix low freemium-to-paid conversion without changing your pricing
  • Write behavior-triggered upgrade emails (limit hit, feature discovery, inactivity)
  • Run a quick audit on why free users are not converting

This skill is about in-product upgrade moments, not public pricing pages. If you need to optimize your pricing page copy or structure, use the pricing-strategy skill instead.


Context Check

Before diving in, gather these details from the user (if not already provided):

  1. Product type — what does the product do?
  2. Free plan limits — what can free users do? Where do they hit walls?
  3. Paid plan differentiators — what does upgrading enable?
  4. Current trigger — when/where does the upgrade prompt currently appear?
  5. Billing stack — Lemon Squeezy, Stripe, Paddle, or other?
  6. Current conversion rate — what % of free users upgrade, if known?
  7. Biggest free user behavior — what do most free users do before churning or converting?

The Upgrade Mindset

Upgrades happen at the intersection of three conditions:

Value is felt  +  Friction is low  +  Price is anchored
  • Value is felt: The user has already experienced a meaningful outcome from the product. They understand what they're paying for because they've lived it.
  • Friction is low: The upgrade path is one click, the checkout is fast, and the pricing is clear. No confusion, no form anxiety.
  • Price is anchored: The user has a reference point that makes the price feel reasonable — a higher tier shown first, a cost-per-day breakdown, a comparison to a familiar expense ("less than one coffee/month").

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.

Upgrades an existing Memex workspace to the current major version in one command. Detects current state (manifest marker, summary-format version, closets coverage) and runs only the needed subset of /memex:resummarize, /memex:reindex, and lint.

Sweeps the workspace for drift -- duplicate files, unannotated decision supersessions, orphans, bloated decisions logs -- on a cadence separate from session-end. Read-only by default; --fix applies safe annotations only (never auto-merges files).

Backfills or rebuilds every hub's CLOSETS.md from scratch, so closets exist immediately instead of accumulating across many session-ends -- for a v1-to-v2 upgrade, a large bulk import, or whenever you want full v2 retrieval quality now.
