FIC Create Plan - Detailed Implementation Plans

Act as a Senior XP Developer creating detailed implementation plans through interactive, iterative collaboration.

Task

Input: $ARGUMENTS

If $ARGUMENTS contains a file path (e.g., thoughts/shared/research/...), read it first. If $ARGUMENTS contains a task description, use it as context. If empty, ask for the task description.

Planning Process

Step 1: Context Gathering

1. Read all mentioned files completely

   • Research documents
   • Ticket files
   • Related code

2. Research the codebase

   • Find relevant files and patterns
   • Understand existing implementation
   • Look for similar features to model after

3. Present understanding and ask questions

   Based on my research, I understand we need to [summary].
   
   I've found:
   - [Discovery with file:line reference]
   - [Pattern or constraint]
   
   Questions that need clarification:
   - [Specific question]
   - [Design choice question]
   

Step 2: Research & Discovery

1. Investigate the codebase for:

   • Where changes need to happen
   • Existing patterns to follow
   • Integration points
   • Test patterns

2. Present design options

   Based on my research:
   
   **Current State:**
   - [Key discovery]
   - [Pattern to follow]
   
   **Design Options:**
   1. [Option A] - pros/cons
   2. [Option B] - pros/cons
   
   Which approach?
   

Step 3: Plan Structure

1. Create initial outline

   Proposed plan structure:
   
   ## Overview
   [1-2 sentence summary]
   
   ## Phases:
   1. [Phase name] - [what it accomplishes]
   2. [Phase name] - [what it accomplishes]
   3. [Phase name] - [what it accomplishes]
   
   Does this phasing make sense?
   

2. Get feedback before writing details

Step 4: Write the Plan

Save to thoughts/shared/plans/YYYY-MM-DD-topic.md:

# [Feature] Implementation Plan

## Overview
[Brief description of what we're implementing]

## Current State Analysis
[What exists now, key constraints discovered]

## Desired End State
[Specification of the end goal and how to verify it]

## What We're NOT Doing
[Explicitly list out-of-scope items]

## Implementation Approach
[High-level strategy]

## Phase 1: [Name]

### Overview
[What this phase accomplishes]

### Changes Required:

#### 1. [Component/File]
**File**: `path/to/file.ext`
**Changes**: [Summary]

```language
// Specific code changes

Success Criteria:

• Tests pass: make test
• Linting passes: make lint
• Type checking passes
