System Atlas

Anatomy is an open-source agent skill for Claude Code, Antigravity, OpenCode, and Codex that explains technical ideas by constructing interactive isometric illustrations of physical machines, instruments, tools, or other mechanisms. It uses a workflow that collects the relevant numbers, invents a physical object for the concept, creates a parts list and geometry, renders parts back to front, adds interaction, and verifies the result with geometry and browser checks. The skill can produce standalone HTML pages, embedded SVG files, or React/Next.js components. Its SVG kit provides isometric solids, round parts, pipes, cables, four-tone shading, animation, cards, and live readouts; optional WebGL layers add effects such as fire, exhaust, water, caustics, light, and glow, while a beta 3D mode re-projects and re-shades moving parts each frame. The repository includes Node build scripts, complete examples, React components, reference guides, and headless Chrome tools for screenshots, scripted interaction, line-end checks, and geometry audits. It uses Node.js built-in modules without npm dependencies for the kit and examples, with React 18+ required for React output and Chrome or Chromium required for browser checks. The project is distributed under the MIT license. Its stated limits include not being a chart library, not targeting people or exact maps, and requiring WebGL for shader effects.

Archify is an open-source agent skill and Node.js rendering and validation system that turns a codebase or system description into searchable, shareable interactive diagrams. It supports architecture, workflow, sequence, data-flow, and lifecycle diagrams and can be used with Cursor, Claude Code, Codex CLI, and OpenCode. Agents produce typed JSON intermediate representations, which Archify deterministically validates and compiles into self-contained HTML and SVG artifacts. The generated viewer supports node search, optional revision-verified source inspection, upstream and downstream reach tracing, route inspection, semantic-role comparisons, guided stories, themes, presets, and finite motion. Archify can compare two validated snapshots as Before, Delta, and After views, identifying added, removed, changed, moved, and rerouted facts. Its exports include PNG, SVG, WebM, and 1200×630 share cards; it can be installed as a global skill with `npx skills add tt-a1i/archify -g`.

Human Atlas is an open-source, browser-based interactive 3D anatomy explorer. It uses selectable BodyParts3D meshes to let users toggle anatomical system layers, search structures, and view exploded arrangements that show how body parts fit together. The video describes it as running locally as a static site without accounts or API keys.

Bot Crossing is a local web application that visualizes coding-agent threads as an astronaut colony. It reads session records from installed agent harnesses on the user's machine, maps repositories to persistent hex zones, and represents sessions as astronauts whose behavior reflects states such as running, waiting, errored, merged, archived, or inactive. Selecting an astronaut or repository opens its associated thread through the owning harness, while the application can also start sessions, reveal folders, mark threads viewed, and archive them. The application uses per-harness adapters to scan local session files and merge them into a common thread model. It currently documents support for Claude Code, Codex, and Cursor, with adapters for other harnesses able to be added under `server/harnesses/`. Astronaut navigation uses a rasterized navigation grid, A* routing, string-pulling, collision handling, and crowd separation. The browser renders the colony with Three.js techniques including instanced GPU-skinned astronauts, shader-based construction progress, procedural terrain and surfaces, and configurable planets, lighting, and quality settings. Bot Crossing runs locally through a Vite development server or a built Node server, binds to loopback by default, and stores the colony layout in `data/colony.json`. It does not upload session data or use an account; it reads harness records and writes only the colony state plus the documented archive field. The repository requires Node 22.13 or newer, supports macOS, Linux, and Windows, and is licensed under MIT. Bundled Kay Lousberg assets are separately covered by CC0, while bundled Material Design Icons use Apache-2.0.

Birdview is an open-source developer tool that makes AI coding agents map a project's architecture before editing. Its Birdview workflow defines modules, responsibilities, file ownership, evidence, relationships, and layout in an architecture JSON file; an agent then declares planned task scope, targets, files, lifecycle phases, and verification records against that map in an activity JSONL stream. Validators check the schemas and cross-record rules before a renderer produces a standalone interactive HTML view with architecture, changes, comparison, module evidence, and activity-history views. Birdview supports automatic or on-demand activation through project-level agent guidance and includes Node.js scripts, JSON Schemas, example maps, and tests. The generated output has no server or network dependency, but the v0.1 implementation is file-based: activity is agent-declared rather than automatically observed, and updates require regenerating the HTML. It is MIT-licensed and is not published to npm.
