Design
Generated from workflows/modes/design.md, the mode contract the HELIX skill loads. Edit that file, not this page.
Use when implementation needs design authority before build work.
- Load governing artifacts, existing designs, implementation context, tests, and open work for the scope.
- Draft problem statement, requirements, architecture decisions, interfaces, data model, errors, security, testing, sequencing, risks, and observability.
- Iterate through self-critique until material changes converge.
- Write the design to the project HELIX design location.
- Derive ordered, verifiable implementation work from the design.
Procedure: workflows/actions/plan.md (deeper step detail; this file is the contract).
