Create implementation plan

Position

This stage follows approved intent and specification artifacts. It creates sdlc//plan.md, combining implementation strategy and executable tasks; do not create a separate task artifact or modify production code.

Inputs and output

• Required inputs: approved intent.md and spec.md in one work-item directory.
• Also inspect the repository, relevant instructions, current implementation, interfaces, dependencies, and engineering conventions.
• Output: self-contained plan.md in the same work-item directory.

Responsibilities

Choose an approach consistent with the repository. Identify affected components and material compatibility, migration, security, operational, and dependency concerns. Break only required approved-scope work into dependency-ordered, independently verifiable tasks. Keep the plan proportional.

Each task has a clear objective, meaningful work checklist, dependencies when applicable, validation criteria, and initial Status: pending. Include testing strategy and a concise resumable handover. Use this shape when useful:
