Skill for generating cheatsheet PDF optimized for the reMarkable eink A developer created an agent skill that generates bookmarked PDF cheatsheets optimized for reMarkable e-ink tablets, turning them into desktop reference screens. The skill supports device-tuned presets, clickable subject indexes, and optional cloud sync via rmapi, enabling users to quickly create and update one-page reference guides for commands, APIs, or workflows. An agent skill for building bookmarked PDF cheatsheets and quick-reference guides for the reMarkable tablet. The reMarkable is good for long-form reading and writing. It is much less good at quick lookup: opening a manual, finding the right section then flipping back again is enough friction that I usually stop doing it This project turns the tablet into a desktop reference screen. The output is a bookmarked PDF where one subject gets one page . By default commands, keys, or API calls are placed at the top; workflows in the middle; gotchas near the bottom; and a blank scratch zone for pen notes The main interface is the agent skill in .agents/skills/cheatsheet/SKILL.md . You can still run the shell scripts by hand but the intended workflow is to ask an agent to create, update, build, preview and optionally sync the cheatsheet for you Device-tuned PDFs - presets for reMarkable Paper Pro 180 x 240mm and reMarkable 2 157 x 209mm , with readable body text Bookmarked subjects - each sheet becomes a clickable PDF outline entry A generated cover index - the first page links to the included sheets Return-to-index button - each page has a small top-right link back to the index, so you can jump home without swiping through pages Scratch space - each page reserves a bottom writing zone for pen notes Agent-guided sheet creation - the skill asks for scope, sources, preset, PDF name, preview and sync choices before editing files Optional preview and sync - render PNG previews with poppler and upload to the reMarkable cloud with rmapi Point your coding agent at this repository and ask it to use the skill file: Use .agents/skills/cheatsheet/SKILL.md and add a cheatsheet page for Zellij. Use official docs, keep the existing library PDF, build a preview and do not push If your agent supports slash commands or local skills, invoke the skill directly: /cheatsheet For a concrete task, give the subject and sources up front: /cheatsheet add a sheet for Codex using https://developers.openai.com/codex/ The skill guides the agent through these decisions: Focused PDF or library PDF - include only the new sheet, or keep all existing sheets and add the new one Device preset - Paper Pro default, Paper Pro dense, reMarkable 2 comfortable, or high contrast Index depth - sheet titles only, or sheet titles plus section entries. PDF name - use a suggested content-based name or provide your own Preview - build one PNG per page for quick inspection Push - upload to the reMarkable cloud via rmapi when configured Use the cheatsheet skill. Add a Docker Compose sheet from the official docs, keep the existing sheets, use paper-pro-dense, build with preview and report the output path and page count Use the cheatsheet skill. Switch this project to rm2-comfortable and show me a side-by-side preview diff before rebuilding the PDF Use the cheatsheet skill. Build the current library, suggest a better PDF filename from the included sheets, but ask before changing cheatsheet.toml For new sheets, prefer official documentation or reputable primary sources The skill should stay conservative: do not invent commands, keybindings, API details, or game mechanics just to fill a page. If the subject is broad, narrow it first: for example, Python packaging is a better sheet target than all of Python | Preset | Page | Body | Scratch | Borders | When to use | |---|---|---|---|---|---| paper-pro-default | 180x240mm | 11pt | 40mm | 0.4pt gray | Default. Balanced for Paper Pro. | paper-pro-dense | 180x240mm | 10pt | 30mm | 0.4pt gray | Fit more commands per page. | rm2-comfortable | 157x209mm | 12pt | 50mm | 0.4pt gray | reMarkable 2. Bigger text, more pen room. | high-contrast | 180x240mm | 11pt | 40mm | 0.8pt black | Frontlight / sunlight / low-vision. | You can override individual values in cheatsheet.toml : preset = "paper-pro-default" scratch zone mm = 55 pdf name = "dev cheatsheet" index depth = 1 The full config schema is in references/config.md /Deca/remarkable-cheatsheet/blob/main/references/config.md . If you want to build without an agent: echo 'preset = "paper-pro-default"' cheatsheet.toml bash scripts/build.sh --preview That writes the PDF to output/
