# Packrift Browserbase Browse Skill Pack

Release: PACKRIFT-BROWSERBASE-BROWSE-SKILL-PACK-R07
Generated: 2026-05-20T22:14:11.754Z
Canonical MCP endpoint: https://mcp.packrift.com/mcp
Browse source-aware endpoint: https://mcp.packrift.com/mcp?packrift_mcp_source=browse_sh&packrift_mcp_target=generic_streamable_http

## Purpose

A thin Browse/browser-skill starter pack for Packrift. It gives agents a canonical SKILL.md playbook for public discovery, then routes all live price, inventory, shipping, and cart handoff through the canonical hosted MCP endpoint.

## Candidate Skill

Name: Packrift exact-spec packaging procurement
Status: catalog_live_installable
Start URL: https://mcp.packrift.com/ai/browser-agent-bridge.json
Root SKILL.md: https://mcp.packrift.com/SKILL.md
Canonical SKILL.md: https://mcp.packrift.com/ai/browserbase-browse/SKILL.md

This is not a Packrift CLI, checkout, or alternate buyer surface. It is a read-first browser-skill wrapper around https://mcp.packrift.com/mcp.

## Browse Catalog Submission

Status: catalog_live_installable
Check command: `browse skills find packrift`
Catalog slug: `packrift.com/exact-spec-packaging-procurement-e4ujmy`
Install check: `browse skills add packrift.com/exact-spec-packaging-procurement-e4ujmy` (pass)
Submission URL: https://browse.sh/
Tracked start URL: https://mcp.packrift.com/r/start/browse_sh
Tracked Codex install URL: https://mcp.packrift.com/r/install/browse_sh/codex
Tracked generic install URL: https://mcp.packrift.com/r/install/browse_sh/generic_streamable_http
Tracked first-run shell: https://mcp.packrift.com/r/run/browse_sh/generic_streamable_http?format=sh
Tracked activation runner: https://mcp.packrift.com/r/activate/browse_sh?format=html

Browse catalog search finds Packrift and browse skills add installs the verified MCP-first skill. This fallback skill pack remains a read-first wrapper around the hosted MCP endpoint for live price, inventory, shipping, and cart handoff.

## SKILL.md

Root URL: https://mcp.packrift.com/SKILL.md
Canonical URL: https://mcp.packrift.com/ai/browserbase-browse/SKILL.md

Use this as the Browse/browser-agent submission artifact or as the direct instruction file for any agent that accepts open-web skills. It does not replace the hosted MCP endpoint.

## Browser-Agent Rules

- Read https://mcp.packrift.com/SKILL.md first when a browser-skill host asks for a single Packrift skill file.
- Use public URLs for read-first discovery, not for final commercial facts.
- Call the source-aware Packrift MCP endpoint https://mcp.packrift.com/mcp?packrift_mcp_source=browse_sh&packrift_mcp_target=generic_streamable_http for get_product, get_pricing, check_inventory, shipping estimates, no-match handling, and create_cart_url.
- Use source_context=browse_sh_first_cart_run, journey_id=mcp_install_browse_sh_1066_53472879935856, and result_set_id=mcp_install_first_run_browse_sh when running the first useful SKU 1066 flow from Browse.
- Use prepare_purchase_handoff when the browser agent already has an exact SKU and needs a compact live-confirmed handoff path.
- Use create_cart_url with sku plus quantity after buyer confirmation; the tool blocks SKU, handle, and variant mismatches and returns a measured /r/cart URL.
- Never present nearby dimensions, material, closure, printer type, pack count, case count, or color as an exact substitute.
- When no exact AI_APPROVE item exists, route to explain_no_exact_match and get_bulk_quote_link instead of forcing a cart.
