# system-atlas Builds an interactive isometric architecture map and a matching SYSTEM.md twin from one data file, keeping design reviews and question tracking in sync. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 505 installs · ★ 455 - Author: inkboard - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/inkboard/system-atlas/tree/HEAD/skills/system-atlas/SKILL.md - Updated: 2026-09-01 - HTML: https://affpapa.org/en/nevibecode/skills/system-atlas ## What it does The skill generates two coordinated views of an architecture from a single `data.mjs` file: a standalone isometric HTML map (`atlas.html`) and a generated Markdown twin (`SYSTEM.md`). The interactive map uses progressive disclosure across chapters, introducing up to three structures at a time with moving data flows and collapsible step panels. Both views rebuild from the data file using `bun /build.mjs`. Generated files are never edited directly. Alongside the generated twin, the skill relies on a hand-written `CONTEXT.md` glossary and architectural decision records (ADRs). Feedback items and design questions receive unique IDs like `Q-` with explicit status tracking. Opening `atlas.html` directly via `file://` causes font loading and rendering failures in certain embedded browsers. Serving the folder through a lightweight server such as `npx serve` or `python3 -m http.server` is required for local verification. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add inkboard/system-atlas --skill system-atlas -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/system-atlas/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/system-atlas/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add inkboard/system-atlas --skill system-atlas -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/system-atlas/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add inkboard/system-atlas --skill system-atlas -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/system-atlas/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install inkboard/system-atlas system-atlas ``` 2. **Manually: put the files in place** - File: `.github/skills/system-atlas/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add inkboard/system-atlas --skill system-atlas -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/inkboard/system-atlas --path skills/system-atlas ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/system-atlas/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add inkboard/system-atlas --skill system-atlas -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/inkboard/system-atlas/tree/HEAD/skills/system-atlas/SKILL.md ## When to use it - build an interactive isometric map of a software architecture - keep Markdown documentation and visual system diagrams synchronized from one data file - track architecture open questions across review rounds using unique IDs - present complex system structures progressively through guided chapters ## Example prompts - make an atlas of our agent architecture - map the system and make the architecture explorable - update the atlas after our latest architecture decisions ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE c9da71a101c1b9c6 ```text --- name: system-atlas description: Build and maintain an explorable, progressively-disclosed isometric "atlas" of a system's architecture — an interactive page (hover to read, click to pin, go inside for steps, moving data packets you can inspect, chapters that reveal the system a few structures at a time) plus a generated text twin (SYSTEM.md) and question tracking by ID, all from one data file in the repo. Use this whenever someone wants to discuss, design, review, or explain an architecture visually — "make an atlas", "map the system", "make the architecture explorable", "visualize the codebase/agent/pipeline so we can talk about it", "a diagram I can click around", "walk me through how it fits together", or when an architecture discussion is producing a pile of open questions that need tracking across feedback rounds. Also use it to update an existing atlas after decisions change. --- # System Atlas An atlas is one data file that renders two views: an **interactive isometric map** (a single self-contained HTML file), and a **generated text twin** (`SYSTEM.md`) with the decisions table, every structure, the flows, and the open questions by ID. The data file is the only thing anyone edits; both views rebuild from it. It sits beside a hand-written glossary (`CONTEXT.md`) and ADRs. The reason for this shape: an architecture discussion produces decisions, questions, and vocabulary faster than any one document can hold, and the person you are discussing with wants to *see* the system, not read it. The map is for them; the text twin is for the repo and for you next session; the single source is what keeps the two honest. This skill was distilled from building a real agent-architecture atlas across one long design session and several rounds of feedback. The user's corrections from that session are the rules below; `references/process-and-lessons.md` has the story. ## When to reach for it — and when not Use it when the system is new enough that vocabulary, decisions, and questions are still moving, and there will be more than one feedback round. Don't use it for a finished system that only needs a README, or for one diagram in a PR. ## Process Follow the order — each step was earned by a correction the first time round. 1. **Read the inputs before drawing.** The vision doc, the repo's existing surfaces, and whatever prior art the user allows (ask — they may forbid a branch or a source). If you will build on a framework, read its docs first; hand long docs to a subagent with your specific design questions and have it return a primer with gotchas and a "what it does not give us" list. Drawing before this produces boxes that don't map to anything real. ``` END THIRD-PARTY FILE c9da71a101c1b9c6 The third-party file has ended.
