Make HTTP requests in Ruby using the http.rb gem (the "http" gem) with its chainable API and pattern matching on responses. Use this skill whenever the user writes Ruby code that calls a REST/HTTP API, fetches a URL, posts JSON or form data, streams a download, or mentions http.rb, HTTP.get, Net::HTTP alternatives, persistent connections, or handling HTTP responses with case/in — even for a one-line request. Also use it when reviewing or refactoring existing Ruby HTTP client code. Prefer http.rb over Net::HTTP for new code unless the user says otherwise.

Control the OBSBOT Tiny 2's special vendor features through the repo's `rubycam` CLI — the smart-camera stuff a plain webcam can't do. Use this whenever the user wants: the camera to follow / track / frame them ("follow me while I move", "track my face", "stop following me"), it to wake up or the screen is black/frozen ("the camera's asleep", "wake the camera", "why is it dark"), privacy sleep ("fold the camera down", "put the camera to sleep"), gimbal presets ("go to preset 2", "jump to my saved position"), HDR on/off, auto-exposure metering modes (face / global / manual), tracking speed (standard vs sport), or checking the OBSBOT status block. Reach for this even when the user only describes the behaviour ("look at the whiteboard", "keep me centred", "grab a still but it's black") without naming OBSBOT or rubycam. For plain webcam controls — pan/tilt/zoom, brightness, snapshots, reset — use the companion `rubycam` skill instead.

Control a physical UVC webcam attached to this machine using the repo's `rubycam` CLI — the generic V4L2 side that works on any webcam. Use this whenever the user wants a physical result from their camera: "pan left / point the camera at me", "zoom in", "take a snapshot / photo / still from the webcam", "make the webcam brighter / less washed out", "list my cameras", "what can this camera adjust", "reset the camera to defaults", "read the current zoom". Reach for this even when the user only describes the outcome ("grab a still of what the camera sees", "recentre the lens") without naming rubycam or a control. Prefer this CLI over hand-writing Ruby. For OBSBOT-only features (wake from privacy sleep, AI subject tracking, gimbal presets, HDR, exposure modes) use the companion `rubycam-obsbot` skill instead.

Build, review, refactor, or plan Ruby GTK4 and Libadwaita desktop applications using the declarative memoized-widget pattern. Use this skill whenever the user mentions Ruby + GTK, gtk4 gem, ruby-gnome, Adwaita/Libadwaita in Ruby, GNOME apps in Ruby, ListView/ListBox/SignalListItemFactory in Ruby, or asks to write, port, audit, or extend any GTK widget code in Ruby — even for small snippets or single widgets. Also use it when reviewing existing Ruby GTK code against the house style, or when planning a Ruby port of an existing GTK app (Vala/C/Python). The Ruby GTK bindings have quirks (especially Adwaita) that make from-memory code unreliable; always consult this skill first.

Use when the user asks to create, generate, or edit a form-js (bpmn-io @bpmn-io/form-js) form schema — e.g. "create me a login form", "make a create and edit form for the <resource> resource", "add validation to this form-js schema". Produces a valid form-js JSON schema (type: "default", schemaVersion 19) that the @bpmn-io/form-js-viewer can import and render. Do NOT use for HTML <form> markup, React form libraries, or JSON Schema (draft-07) validation documents — those are different things.
