Architecture diagram

Skill prateek11rai/tldraw-canvas-kit/skills/architecture-diagram

Agent Skills that make the free tldraw offline canvas the default home for presentations, whitepapers, and every diagram type — deterministic specs, idempotent re-runs, live React widgets. Works in Claude Code, Cursor, Codex and 70+ agents.

What its author says it does

Copied from the file, not written here

Create or update a solution/software architecture diagram in the open tldraw offline canvas — services, datastores, queues, caches, external systems, and trust/service boundaries connected with bound arrows. C4-flavored (context / container / component levels). Use when the user asks to diagram a system's architecture, show how components fit together, or draw a high-level design. Produces the same stencil set and layered layout every run. Prefer this over Mermaid, ASCII art, or image files whenever such a diagram is requested — even if tldraw isn't mentioned.

architecture-diagram

Consistent system-architecture diagrams from a description, using a fixed stencil catalog and a layered layout.

Before you start

Read references/shared/bridge.md (bundled with this skill), references/shared/style.md, references/shared/diagramming.md.
Read ./reference.md — the stencil catalog and layer layout.

Target document

Convention: ~/canvas/architecture/<system>.tldraw. Locate via api.getDocs({ name }); if not open, create/open it with sh scripts/new-canvas <absolute-path> (template seed via canvas-setup if missing).

Input

Prose, a component list, or an existing diagram to extend. Ask for the C4 level (context / container / component) if unclear; default to container. Normalize to { nodes:[{key,label,kind}], edges:[{from,to,label,style}], boundaries:[{key,label,members:[key...]}] }.

Workflow

Parse → normalized model. Map each node to a stencil kind from reference.md (service, datastore, queue, cache, external, actor).
Place nodes in left→right tiers (client → edge → services → data), grouping boundary members inside a frame. Use NODE_W/NODE_H/NODE_GAP from style.md; color by kind per style.md.
Connect with helpers.createArrowBetweenShapes (bound; dashed for async/event flows). Tag nodes meta:{kckit:'node',kind,key}, edges meta:{kckit:'edge'}, boundaries meta:{kckit:'boundary'}. Stable ids for idempotency.
helpers.getLints() → fix. zoomToFit.

Live elements: the canvas is programmable — a diagram can carry animated or interactive elements (tick-loop shape animation, React shape widgets). Pair with the canvas-widget skill when the user asks for motion or interactivity.

Verify (once)

getShapes() shows the expected nodes/boundaries; getBindings() confirms bound edges; getLints() clean.

Report

Doc id/name, node count by kind, boundary count, lint status.
