Design

Design (Entry)

Check the current system first, then choose the smallest sufficient path.

When to activate

• Entering the design phase (workflow / plan_only / light_iterate).
• Need to convert requirements into a plan package and task list.

Execution skeleton

1. Load references/design-rules.md.
2. Check existing implementation, governing contracts, applicable platform capabilities, and installed dependencies.
3. Choose the smallest sufficient path and select light/standard/architecture.
4. Generate the plan files from the matching assets/ templates.
5. Produce tasks with explicit dependencies and verification.
6. Report Ready or Needs decision with evidence using assets/output-summary.md.

Resource navigation

• Long rules: references/design-rules.md
• Shared writing standards: ../references/shared-writing-dna.md (apply to all output)
• Output contract: ../references/output-contract.md (required sections, conditional enhancement, self-check)
• Templates: assets/*.md
• Deterministic level selector: scripts/select_plan_level.py

Deterministic logic first

Use the selector when plan.level=auto must be auditable:

python3 skills/en/skills/sopify/design/scripts/select_plan_level.py \
  --file-count 6 \
  --new-feature \
  --cross-module

The script returns JSON with the suggested level and explicit reasons.

Boundaries

• This skill does not execute code changes directly; hand off to develop.
• This skill does not handle routing or protocol state writes; it defines the plan structure and task contract only.
