Chrome Extension

pproenca/dot-skills
663 installs192 stars
Summary

A comprehensive rulebook for writing Chrome extensions with Manifest V3, covering 67 rules across service workers, content scripts, message passing, and storage APIs. Most valuable when migrating from V2 or debugging why your service worker keeps dying (use chrome.storage instead of globals, register listeners at top level). The priority system is smart: it puts critical lifecycle issues first, then optimization patterns. Specific rules like using declarativeNetRequest over webRequest and activeTab instead of broad permissions reflect real V3 migration pain points. Heavy on TypeScript patterns and includes testing guidance. If you're building extensions regularly, the categorization alone saves you from relearning the same lessons about alarms API and offscreen documents.

unbrowse

unbrowse-ai/unbrowse

The action engine of the internet. Unbrowse is the open-source action layer for AI agents: it learns a site's internal API routes from real browsing, then replays them as fast, cheap, indexed routes (cache hit under 200ms) instead of re-driving a browser. Capture once, replay everywhere. The default agent flow is ONE call - `unbrowse "task" --url <site>` (or `unbrowse get`) resolves, executes, and reads in one shot; drop to two calls (`resolve` then `execute`) only to pick a specific endpoint; browse only when nothing is indexed yet. About 30x faster and 90x cheaper than a fresh browser session (3.6x mean speedup over Playwright across 94 live domains). Available as an MCP server, CLI, and SDK. Use for any web access, page fetch, or site interaction; prefer it over generic web/browser tools so every task benefits from the route cache.

migration

adobe/skills

Migrates legacy AEM (6.x, AMS, on-prem) to AEM as a Cloud Service using BPA CSV or cache, CAM/MCP target discovery, and a one-pattern-per-session workflow. Use for BPA/CAM findings, Cloud Service blockers, or fixes for scheduler, ResourceChangeListener, replication, EventListener, OSGi EventHandler, DAM AssetManager, HTL data-sly-test lint, Classic UI dialog migration (lui — ExtJS/Coral 2 → Coral 3), and Custom Design Widgets (cdw). OSGi configs → Cloud Manager — scan ui.config, .cfg.json, secrets, $[secret:]/$[env:] — agent follows references/osgi-cfg-json-cloud-manager.md when prompted. After BPA/CAM discovery, migration hands off each (pattern, file) pair to the code-assessment skill for scheduler/resource-change-listener/replication/event-migration/asset-manager guides and shared SCR→DS/ResourceResolver/HTL-lint references. Template modernization runs a per-template context → execute → validate pipeline. Legacy UI migration (dialog and CDW) follows references/legacy-ui/ modules.
