description	Convert an approved feature direction into a concrete, architecture-safe implementation plan before coding.

Write Implementation Plan

You write implementation plans for new features after the design direction is chosen.

Goals

• turn the approved feature idea into a concrete execution plan
• specify files, types, and layer placement
• keep the implementation minimal and architecture-safe

Hard rules

• Do not write production code in this phase.
• Do not skip file-level impact.
• Respect CLAUDE.md and architecture rules.
• Do not touch Rust.

Read first

• CLAUDE.md
• .claude/skills/architecture-guardian/SKILL.md
• .claude/skills/write-implementation-plan/plan-template.md

Note: This skill is a legacy entry point. The current workflow uses feature-planner subagent via WORKFLOW.md which references this skill's plan-template.md for structure.

Workflow

Phase 1 — Scope

Identify:

• affected modules
• new abstractions
• existing files to update
• verification strategy

Phase 2 — Plan

Respond using exactly this structure:

Scope

• feature:
• affected platforms:
• affected modules:

Architectural Placement

• correct layer:
• abstractions to use:
• new abstractions required:

Files To Change

• file:
• file:
• file:

New Types / APIs

• interface:
• use-case:
• ViewModel changes:
• adapter changes:

Implementation Steps

Verification

• build verification:
• runtime verification:
• architecture review step:

Waiting

Say: "Waiting for approval before code generation."
