Build inline interactive HTML widgets with show_widget — charts, diagrams, dashboards, sliders, side-by-side comparisons, or any visual explainer. Load before non-trivial widget work for design rules and scenario skeletons.
Use when the user asks to create, scaffold, or edit Jupyter notebooks (`.ipynb`) for experiments, explorations, or tutorials; prefer the bundled templates and run the helper script `new_notebook.py` to generate a clean starting notebook.
Prepare and publish cubeplex releases across backend, frontend, sandbox, Helm, Docker Compose, Git tags, and container registries. Use when cutting a release, bumping release versions, publishing Docker images, promoting image digests, updating deployment values, or troubleshooting release ordering.
Use when writing internal communications such as status reports, leadership updates, 3P updates, company newsletters, FAQs, incident reports, and project updates.
Use this skill when visual quality and design identity matter for a PDF. CREATE (generate from scratch): "make a PDF", "generate a report", "write a proposal", "create a resume", "beautiful PDF", "professional document", "cover page", "polished PDF", "client-ready document". FILL (complete form fields): "fill in the form", "fill out this PDF", "complete the form fields", "write values into PDF", "what fields does this PDF have". REFORMAT (apply design to an existing doc): "reformat this document", "apply our style", "convert this Markdown/text to PDF", "make this doc look good", "re-style this PDF". This skill uses a token-based design system: color, typography, and spacing are derived from the document type and flow through every page. The output is print-ready. Prefer this skill when appearance matters, not just when any PDF output is needed.
Open, create, read, analyze, edit, or validate Excel/spreadsheet files (.xlsx, .xlsm, .csv, .tsv). Use when the user asks to create, build, modify, analyze, read, validate, or format any Excel spreadsheet, financial model, pivot table, or tabular data file. Covers: creating new xlsx from scratch, reading and analyzing existing files, editing existing xlsx with zero format loss, formula recalculation and validation, and applying professional financial formatting standards. Triggers on 'spreadsheet', 'Excel', '.xlsx', '.csv', 'pivot table', 'financial model', 'formula', or any request to produce tabular data in Excel format.
Use at the START of a large, unclear, or multi-subsystem cubeplex feature — before writing code — to isolate work, resolve the design, and write a spec/plan under docs/dev. Clearly specified, small, single-concern tasks skip spec, plan, clarification, and review and execute directly. Covers worktree provisioning (./scripts/new-worktree), reading .worktree.env for allocated ports/DBs, brainstorming requirements, and one-concern-per-PR planning. Triggers on phrases like "做个新功能", "开个 worktree", "先写 spec/plan", "怎么开始这个 feature", "plan before code", "brainstorm 一下需求".
Create polished, fully-editable Word (.docx) documents end to end — research or read the source, outline the structure, pick a style set, build native editable content (cover / headings / body / lists / three-line tables / figures / quote / TOC / page numbers), then self-check before delivering. Handles English and Chinese (including 公文 / GB-T 9704 layout). Use whenever the user wants a report, paper, proposal, letter, memo, contract draft, or any Word document. Free fonts + open libraries only.
