The pipeline, documented at v2.17.0-dev.1 with integrations for Cursor, Claude Code, Codex CLI, and OpenCode, is designed to catch LLM-hallucinated dependencies and layout errors that monolithic visual generators hide. The developer argues diagrams should be verifiable against authored topology rather than trusted as polished but unverified assets.", "body_md": "It is 3:00 AM, database connections are dropping, and the on-call engineer is staring at a diagram routing traffic through a cluster decommissioned six months ago. The diagram looked immaculate in Notion, passed review without objection, and actively lied about production topology.\n\nDrawing boxes is cheap. Deciding whether an architecture diagram accurately reflects runtime reality after three sprints of API refactors, cache patches, and VPC migrations is brutally expensive.\n\nWhen AI coding assistants entered the pipeline, drift accelerated. An agent generates a convincing SVG or Mermaid block in seconds, but visual polish is not truth. Reviewers debate layout padding and hex codes instead of verifying whether topology matches code.\n\nI evaluated `tt-a1i/archify` as an external developer seeking a verifiable pipeline for AI-assisted architecture mapping. Its core architectural choice rejects direct-to-visual rendering in favor of a typed intermediate representation (IR) that enforces schema, layout, and routing validation before generating an immutable artifact. The current repository (`v2.17.0-dev.1`) documents integration across Cursor, Claude Code, Codex CLI, and OpenCode.[1]\n\nThe compilation pipeline enforces explicit operational boundaries:\n\n```\nAgent prompt or repository analysis\n              |\n              v\n      Typed JSON intermediate form\n              |\n              v\n Schema + layout + route validation\n              |\n              v\n Deterministic HTML/SVG artifact\n              |\n              v\n PNG, SVG, WebM, or share-card export\n```\n\nDecoupling topology generation from visual presentation isolates distinct failure modes. If an LLM hallucinates a dependency, the schema gate fails. If a layout engine overlaps labels, the layout gate catches it. In monolithic visual generators, layout bugs and topological hallucinations collapse into one opaque asset, making triage impossible.\n\nToy tutorials stop once an agent dumps Mermaid into markdown. In production systems, reality breaks immediately:\n\nArchify attacks this by treating authored nodes and edges as strict invariants. Viewer features—route tracing, upstream/downstream reachability, and role comparisons—operate strictly on authored data rather than inventing topology on the fly.[1]\n\nA diagramming tool should make declared architecture inspectable. It must never fabricate runtime safety or guess network reachability.\n\nFor a global Cursor configuration:\n\n```\nnpx -y skills add tt-a1i/archify \\\n  --skill archify \\\n  --agent cursor \\\n  --global \\\n  --copy \\\n  --yes\n```\n\nFor project-level discipline, commit the skill into the repository and store generated JSON alongside source code. A minimal configuration handles visual styles without mutating underlying topology:\n\n```\n{\n  \"meta\": {\n    \"locale\": \"en\",\n    \"animation\": \"trace\",\n    \"visual_preset\": \"signal-flow\"\n  }\n}\n```\n\nThe `meta` block configures presentation. It does not dictate system topology. Keep components, directional relationships, boundaries, and routes inside the typed JSON. The compiler guarantees deterministic output for identical inputs.\n\nWhen prompting Cursor, constrain the model's blast radius:\n\n```\nAnalyze this repository, then use archify to create a runtime architecture diagram.\n\nInclude:\n- 8-12 core components\n- one primary request path\n- cache fallback behavior\n- external dependencies\n- trust boundaries\n\nUse authored relationships only. Put secondary detail in component cards.\nDo not infer runtime impact or merge safety.\n```\n\nNever inspect an unverified artifact. Validate through the compiler toolchain:\n\n```\nnode archify/bin/archify.mjs doctor\n\nnode archify/bin/archify.mjs validate \\\n  architecture \\\n  examples/web-app.json \\\n  --quality showcase \\\n  --json\n\nnode archify/bin/archify.mjs deliver \\\n  architecture \\\n  examples/web-app.json \\\n  /tmp/web-app.html \\\n  --quality showcase \\\n  --json\n```\n\nArchify runs multi-stage validation checks across JSON schema, layout geometry, HTML/SVG emission, route continuity, and label clearance.[1] The `deliver` command writes to the target only after every gate passes. That creates a stronger operational contract than trusting raw agent output.\n\nFile watchers that reload on every disk write introduce severe friction: an editor saving intermediate syntax wipes out working diagrams during live reviews.\n\nArchify binds a loopback HTTP server to watch the source JSON, refreshing the rendered view only when candidate syntax passes full validation. Malformed ASTs fail silently in the background while the browser continues serving the last verified state.[1]\n\n```\nnode archify/bin/archify.mjs preview \\\n  architecture \\\n  examples/web-app.json \\\n  /tmp/web-app-preview.html \\\n  --quality showcase \\\n  --no-open\n```\n\nFor pull request reviews, comparing raw diagram screenshots is useless. Archify provides structured topology diffing:\n\n```\nnode archify/bin/archify.mjs compare \\\n  architecture \\\n  base.json \\\n  head.json \\\n  architecture-delta.html \\\n  --json\n```\n\nThe delta compiler isolates added, removed, mutated, and rerouted edges directly in the visual DOM.[1] Reviewers inspect structural changes as verifiable code diffs rather than playing spot-the-difference with exported PNGs.\n\nArchify is not an unconstrained whiteboarding canvas. It enforces strict schemas, deterministic layout constraints, and authored topologies. That adds friction when you simply want to scribble a napkin sketch. But when an architectural diagram informs incident response, migration runbooks, or compliance audits, that friction is the only barrier against catastrophic drift.\n\nThe hardest operational dilemma in architecture documentation has never been how to draw components; it is whether an engineering team is willing to treat system topology as a compile-time invariant or continue accepting unverified visual folklore.\n\nHow does your team ensure production diagrams reflect live infrastructure rather than outdated design docs?
