Deep Analyze

Trigger

• Keywords: deep analyze, deep analysis, deep dive, roadmap, deep-analyze

When NOT to Use

• Architecture advice only (use `/codex-architect`)
• Tech spec writing (use `/tech-spec`)
• Feasibility analysis (use `/feasibility-study`)

Agent Dispatch

Agent({
  description: "Deep-dive analysis with actionable roadmap and alternatives",
  subagent_type: "solution-architect",
  prompt: `Perform a deep analysis of the following initial proposal.
Follow the analysis framework and output format defined in this skill.`
})

Task

Input

$ARGUMENTS

Analysis Flow

Phase 1: Understand & Validate

1. Extract the core objectives of the initial proposal 2. Identify key assumptions (which may be wrong) 3. List technical points that need verification

Phase 2: Code Deep Dive

Research the existing codebase thoroughly. **Must verify**:

• Naming conventions
• DI injection patterns
• Error handling patterns
• Implementation patterns of similar features

Phase 3: Roadmap Output

Based on the research, produce: 1. Implementation steps (immediately actionable) 2. Key pseudocode (only core 1-3 lines, omit if not necessary) 3. Alternative comparison

Output
