What problem does it solve? Running a 3x-ui proxy panel involves operational knowledge that tool schemas cannot express: the order to perform tasks in, unit pitfalls (milliseconds vs seconds, bytes vs GB), which settings silently break clients, and which destructive calls have no undo. This Skill routes any panel task to the right procedure and carries that hard-won operating knowledge verified against Xray-core and 3x-ui sources. ## Core Features & Use Cases - REALITY inbound setup and repair: Choose and verify a camouflage target with scan tools, generate x25519 keys and shortIds, build the VLESS-REALITY inbound, and fix one that stopped getting through. - Connectivity diagnosis: Work from cheapest cause outward — scope the outage, check the core and logs, the inbound, client limits, routing, and the node — with actual Xray log error strings mapped to causes. - Panel hardening and lifecycle operations: Scoped API tokens, credential rotation, fail2ban, backups, plus client onboarding, bulk renewals, usage reports, and safe cleanup of depleted accounts. - Routing, CDN fronting, and multi-node clusters: Split routing by domain/geo token, provider outbounds (Warp/NordVPN/PIA), WebSocket/gRPC/xhttp behind Cloudflare, port-443 fallbacks, and node management with TLS pinning or mTLS. - Use Case: A user reports "it stopped working." The Skill directs the agent to scope the outage with get_online_clients, inspect get_xray_logs for a rejected template, check the client's expiry and quota fields with correct units, and test routing with test_route — all read-only steps before any change. ## Quick Start Ask the agent to set up a VLESS-REALITY inbound on your 3x-ui panel, or describe the problem such as "this client cannot connect" or "route these domains through Warp," and it will follow the matching procedure.
