What it does

This skill turns high-level design plans into actionable implementation plans for engineers who have no prior context on the codebase. It enforces scope checks, codebase verification via subagents, external dependency research, and generates granular tasks with absolute paths, acceptance-criteria mapping, and test requirements. The output is a set of phase files and a test-requirements.md ready for execution.

When to use it

Use when a design document exists and you need a runnable implementation plan (≤8 phases) that includes codebase verification, dependency research, and per-phase tasks. It is intended for teams that want reproducible, reviewable plans and explicit verification steps before coding begins.

What's included

Scripts: none bundled (has_scripts=false)
References: extensive procedural guidance embedded in the skill body; expects use of subagents like codebase-investigator and internet-researcher.
Instructions: step-by-step templates for tasks, markers for parsing, and finalization & test-requirements generation workflows.
