Included Skills2

crawl-websites-with-relskills/crawl-websites-with-rel/SKILL.md

Design, implement, diagnose, or operate restartable website crawlers through REL's embedded Chromium sessions. Use for interaction-heavy or difficult sites that require rendered-link discovery, native clicking, page-readiness waits, browser-history Back, named Profiles, HTML and metadata captures, checkpoints, bounded retries, or session recovery. Prefer rel-browser for one-off browsing that does not need a reusable crawl.

rel-browserskills/rel-browser/SKILL.md

Use REL's local MCP server to read web content, inspect service health, reuse persistent embedded Chromium sessions, capture rendered HTML or screenshots, attach to pages, perform browser actions, and select configured proxy aliases. Use when a request explicitly mentions REL or asks the agent to browse through an existing REL session, keep browser state on the local Mac, or automate a page with REL rather than another browser backend.
