Drawio AWS Reference

Produce AWS architecture diagrams as editable .drawio files using the AWS 2026 shape set (mxgraph.aws4 stencils), with verified stencil names and a validator. Use this whenever an AWS architecture diagram is requested, revised, or reviewed, including when the user only says "draw the architecture", "diagram this", "make me a schema", "hazme un diagrama", or hands over a design document that needs a visual. Also use it when converting a Mermaid sketch into a real draw.io file. Do not use it for non-AWS diagrams.

# AWS architecture diagrams in draw.io

The goal is to hand over a `.drawio` file the user can open and adjust without
rebuilding nodes. Most rework comes from four mechanical mistakes, and all four
are avoidable by following this spec literally.

Mermaid is fine for iterating on the logic inside the conversation. The
deliverable is always `.drawio`.

## Source of truth

When the user supplies both a prose description and a Mermaid sketch, **the
prose wins.** Mermaid is a convenience for reading the shape of the system, and
it drops detail: a flow mentioned in the description but missing from the
diagram is still a flow.

Read both, then check for **orphans**: any resource with no edge in or out. A
bucket nothing writes to, a queue nothing reads, a database nobody queries. An
orphan is almost always a gap in the source description rather than a real dead
end. Ask before drawing it, and say which flow you think is missing.

## Required workflow

1. Settle the logic of the diagram in text or Mermaid, and confirm it with the
   user before writing any XML.
2. Look up every name: service icons in `reference/resicons.txt`, VPC
   sub-components and actors in `reference/shapes.txt`, containers in
   `reference/groups.md`. Never write a stencil name from memory.
3. Write the `.drawio` file.
4. Run `scripts/validate.py` against it and fix everything it reports as an
   error.
5. Deliver, and close with the handover note below.
