suibianqugenichenghaole Bundle

Generate and iterate product demos from a structured requirement skeleton, focusing on demo structure / page planning (not a runnable build) — pages, modules, states, interaction flow, and business-rule expression rather than generic UI beautification. Use when a requirement is ready for prototype/draft-level visualization, when a product manager wants a clickable demo to validate and tweak, or when business rules, state changes, target users, design context, and backend-config effects must be reflected in demo output. For a runnable React implementation, route to pm-react-prototype-execution.

suibianqugenichenghaole Skill

Turn screenshots, design mockups, and prototype references into stable component, page-skeleton, and rule updates for the PM + React workflow instead of one-off imitation.

tronghieu Bundle

Build interactive presentation websites — slide decks projected to a room, controlled by one presenter. Use this skill WHENEVER the user wants to create, build, or design a presentation, slide deck, talk, or "bài thuyết trình / slide / trình chiếu", and also when they ask to add/edit slides, restyle a deck, scaffold a new presentation project, reuse their presentation setup in another repo, or export slides to PDF — even if they don't say the word "slide" but clearly need projected talk visuals (e.g. "I'm giving a talk next week and need visuals", "dựng deck cho buổi chia sẻ", "làm mấy trang chiếu cho hội thảo"). Supports two tracks: a zero-build single HTML file, or a Vite + React project. Do NOT use it for printable documents, normal web apps, or dashboards meant for individual users to interact with.

validkeys Bundle

Detects React/webapp changes from the implementation plan and technical requirements. When UI work is found, generates a structured wireframe specification (wireframe-spec.yaml) and low-fidelity Pencil (.pen) wireframes using a shared design library for consistency.

fnord123 Bundle

Split a saved Gmail thread page into one plain-text file per message, keeping only each message's own words — quoted reply text is removed — with the sender and the send date as the file's header. PREFER THIS SKILL whenever the user shares a Gmail thread (a saved .html page of a whole conversation, or a link they ask to be broken up message by message) and wants the individual messages out of it: extracting the thread into separate files, pulling one message out of a long thread, or tidying a thread export so replies don't drown the original words. Not for single standalone emails, inboxes, or sending mail — this only reads a saved thread page. Activate on any of: "extract the messages from this thread", "split this thread into separate files", "pull out each message", "save this conversation one file per message", "get the original messages out of this Gmail thread", "the quoted text is hiding the actual replies", or anything that sounds like unpacking a Gmail thread into its individual messages.

Covers API-token auth, the universal search endpoints (relative/absolute/histogram/terms), Lucene query DSL, stream scoping, GELF/syslog level pitfalls, UTC time-window handling — and the deliverable: findings published as a shareable HTML report (Claude Artifact).

Reviewer is a grumpy senior content editor for English-language copy (articles, LinkedIn posts, landing-page copy, docs, llms.txt). It issues a verdict (disaster/weak/mediocre/ok) and a list of charges anchored to `file:line`. It never suggests fixes - it only points out what is wrong. Invoke when the user addresses "reviewer?", "review this", "what's wrong with this post", "tear this apart", "be my editor" - whenever the user asks for an opinion on a piece of text. By default it reviews `git diff HEAD` of `.md`/`.html` files, otherwise the most recently edited content files or a file the user names. English counterpart of marko-pl-content.
