natejswenson Bundle

The one brand system for everything produced in Claude — design tokens, the visual laws, the run-presentation contract, and the universal voice core. Use when composing or restyling any artifact (report, résumé, card, cover, PDF, HTML page, chart), when asked about brand colors, fonts, the accent law or "the PRESS look", when adding a new skill that renders anything, or when a brand value needs to change everywhere at once. Also handles "check the brand is in sync", "why do my colors differ", and onboarding a new consumer repo.

natejswenson Bundle

Write an executive summary of the work actually shipped over a chosen time frame, built from real GitHub contributions and real Claude Code session transcripts, ranked so only what mattered appears, and rendered as a press-styled HTML report. Use when the user says "what did I ship this week", "shipreport", "write my weekly summary", "executive summary of my work", "status report for my manager", "what did I get done last month", "summarize what I shipped in July", or wants their commits, merged PRs, cut releases and coding sessions turned into a report someone who wasn't there can read.

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

dailybothq Bundle

Optional DeepWorkPlan addon that gives a repo with a user-facing interface surface a DESIGN.md (under docs/, indexed from AGENTS.md) — a Markdown design-system file any coding agent reads to generate interface output consistent with the repo's OWN conventions. Covers three profiles detected independently from real files — visual-ui (rendered web/mobile/desktop UI), cli-output (styled terminal output — semantic colors, panels, spinners, prompts, TTY/NO_COLOR degradation), and conversational (chat/email messaging — voice and register, message anatomy, per-platform rendering). Reasons about the repo's ACTUAL design source (CSS custom properties, Tailwind config, token files, component styles, a CLI display/theme module, or message-composition helpers) rather than copying a brand file; checks contrast (WCAG AA), color-is-not-the-only-carrier, plain-text fallbacks, and token integrity. The visual-ui profile is default-on when detected (applied in trust mode, strongly recommended in guided mode); cli-output and con
