usbmon

Use when capturing, analyzing, or debugging USB bus traffic for TinyUSB device development on Linux — enumeration failures, STALLed control transfers, missing/short bulk or interrupt transfers, isochronous/audio dropouts, or descriptor problems. Captures host-side URBs with usbmon + tshark into a Wireshark pcapng and decodes them. Use whenever you need to see what the host actually exchanged with a device on real hardware, even if the user just says "sniff USB", "capture the enumeration", or "why won't my device enumerate".

edenfs-systemd-triage

Triage systemd-managed EdenFS issues on Linux devservers and OnDemands. Use when investigating EdenFS service failures, unexpected restarts, systemctl errors, edenfs_upgrade/edenfs_restarter problems, or when a user reports EdenFS is down on a systemd-enabled host. Also use when someone asks how systemd-managed EdenFS works, how to monitor it, or how to check its health. Use when asked to build a timeline of EdenFS lifecycle events, show edenfs restart history, or understand how edenfs reached its current state. Trigger on mentions of edenfs systemd, edenfs@ service, edenfs_upgrade timer, edenfs auto-restart, eden status --debug, systemctl edenfs, edenfs lifecycle management, edenfs timeline, edenfs restart history, or "what happened to edenfs".

Covers throw-site trace rules, component choice, errorType, noise filtering, gating, and testing.

plasmic-designer

Build and modify Plasmic Studio designs using copilot tools via Chrome DevTools MCP. First argument should be a project ID, followed by the design request. Use this skill whenever the user mentions Plasmic, Plasmic Studio, visual web builder, or asks to design, build, edit, or modify UI components, pages, sections, or layouts inside a Plasmic project. Also trigger when the user references a Plasmic project ID, wants to add/remove/restyle elements in a visual editor, or asks about Plasmic component props, variants, slots, or tokens — even if they don't say "Plasmic" explicitly but describe visual design work that implies it.
