Architecture Design

Produce a well-reasoned architecture design document with source-controlled, editable diagrams. Design only—do not implement the system while this skill is active unless the user explicitly changes the task.

Required companion skill

All diagram behavior is owned by draw-diagram. This skill owns architecture discovery, decisions, trade-offs, document structure, and the semantic brief for each diagram; draw-diagram owns diagram tooling and execution.

Before planning, drafting, or rendering any diagram:

1. Load and read the complete draw-diagram skill using the environment's skill loader when available.
2. Otherwise resolve it relative to this file as ../draw-diagram/SKILL.md and read it completely.
3. Follow its current instructions for tool choice, diagram notation, Iconify sourcing, editable sources, rendering, routing, inspection, output paths, and visual quality.
4. Treat draw-diagram as canonical. Do not reproduce or override its operational drawing instructions here.

If draw-diagram cannot be found, stop before diagram work and tell the user to install it:
