Archify

Archify is not a diagram editor but a skill for an agent. One command, `npx skills add tt-a1i/archify -g`, installs it into Claude Code, Cursor, Codex CLI or opencode. From then on the agent understands "draw how our payment flow works" and returns an interactive HTML diagram: dark and light themes, node search, path tracing, export to PNG, SVG, WebM and 1200×630 share cards.

Five types: architecture, workflow, sequence, data flow, lifecycle. Under the hood the agent writes a small typed JSON and the Archify renderer compiles it into SVG deterministically, so the same file always produces the same picture. The difference from "ask a model to draw it" is that nine checks run before delivery, from schema to geometry, and an arrow that cuts through an unrelated node or a label that lands on a neighbouring line never reaches you. The validator returns a rule code and supported fixes, the agent repairs and re-checks.

It can read a repository: architecture nodes may be pinned to files and line ranges at a specific commit, and `compare` shows what was added, removed and moved between two versions of a diagram. As of 4 September 2026 the project has 47,000 stars, 24,000 of them gained in one week, an MIT licence and version 2.17. Needs Node 18 or newer; on our 22.14 everything ran.

What it is not: it reads Mermaid but is not a Mermaid theme, and WYSIWYG editing and hosted sharing are out of scope by design. It is a tool for an agent and a terminal, not a Figma replacement.
