# Free sample — SKU Sunset Policy Pack

**Skill ID:** `gf-pc-sku-sunset-policy-pack`  
**Unlock:** $3.99 / unlock USDC on Base via x402  
**What you get after pay:** runnable sealed pack (`createSkill().run`) + workbook + templates  

## Summary

Deprecation calendars, buyer notices, and cart-block rules for retiring agent marketplace SKUs without silent checkout failures.

Policy and ops pack for SKU sunset: announce windows, last-order cutoffs, replacement SKU maps, agent cart blocks, and refund-boundary notes so retiring listings stay predictable for buyers and partner fee reports.

## When to use

- You are retiring a skill or digital good and need a dated announce-to-block calendar
- Agent carts still quote a delisted SKU and fail only at pay time
- Partner fee and GMV reports must mark sunset orders versus active catalog sales

## Decision-grade outline (free)

1. Build a sunset calendar with announce_at, last_order_at, cart_block_at, and hard_delete_or_archive targets per SKU
2. Draft buyer and agent notice templates that name end dates, replacement SKU if any, and what already-paid unlocks retain
3. Define cart and quote block rules so agents refuse new lines after last_order_at without silent null responses
4. Map replacement and grandfather paths for multi-seat or subscription-adjacent unlocks still inside active windows
5. Tag sunset SKUs in fee and GMV export dimensions so finance can exclude or segment retired catalog lines cleanly

## Capabilities

- Per-SKU sunset calendar template
- Buyer and agent deprecation notices
- Cart and quote block rules
- Replacement and grandfather path notes
- Sunset tags for fee and GMV exports

## Artifacts after unlock

- `sku-sunset-calendar.csv`
- `sku-deprecation-notices.md`
- `cart-block-rules.json`
- `sunset-gmv-tagging-notes.md`

## Detailed description

SKU Sunset Policy Pack helps agent marketplace operators retire listings without surprising buyers at pay time or corrupting partner fee history. Many catalogs delist pages while agents still hold stale quotes; this pack forces a dated calendar—announce, last order, cart block, archive—per SKU and ships notice templates for human and agent channels. Notices state what already-paid unlocks retain and whether a replacement SKU exists, without inventing loyalty bonuses or revenue promises. Cart and quote block rules tell integrators to hard-fail new lines after cutoff with explicit error codes rather than empty payloads. Grandfather notes cover multi-seat or recurring-adjacent access still inside an active window. Export tagging guidance marks sunset SKUs so confirmed-GMV and partner fee reports can segment retired lines. Free outline eval is available to align the calendar fields with your catalog admin before purchase. Unlock settles with x402 Base USDC. Material is operational policy structure only—not legal, financial, or tax advice—and it guarantees no retention, revenue, or traffic outcomes. Coordinate final buyer rights language with counsel and your published refund policy.
