Explain Output Templates

Overview

Provides structured output templates for the 5 explanation modes. Each template defines sections, content depth, and formatting requirements for consistent, high-quality explanations.

Mode Selection

Mode	Target	Depth	Audience	Trigger
quick	Single file	1-2 screens	Developer	File path
deep	Module/directory	Full analysis	Senior dev / Architect	Directory path
onboarding	Entire project	Comprehensive guide	New team member	. or project root
business	Feature/process	Non-technical	PM / Stakeholder	Explicit mode
qa	On-demand	Answer-focused	Any	Explicit mode

Template: Quick Mode

For single file analysis. Compact, fits 1-2 terminal screens.

# Explanation: {FileName}

## Purpose
{One sentence — what this class/file does and why it exists.}

## Business Context
{Which business process or domain concept this participates in.}

## Key Responsibilities
- {Responsibility 1 — what it does}
- {Responsibility 2 — what it does}
- {Responsibility 3 — what it does}

## Business Rules
| Rule | Location | Description |
|------|----------|-------------|
| {rule name} | Line {N} | {what the rule enforces} |

## Data Flow

{Entry} → {Processing step 1} → {Processing step 2} → {Output}

## Dependencies
| Dependency | Role | Direction |
|------------|------|-----------|
| {ClassName} | {what it provides} | {inbound/outbound} |

## Important Notes
- {Non-obvious behavior, edge case, or architectural decision}

Guidelines:

• Maximum 40-50 lines of output
• No diagrams (too verbose for quick mode)
• Focus on "what" and "why", not "how"
• Use business language where possible

Template: Deep Mode

For module/directory analysis. Full analysis with diagrams.

# Deep Explanation: {Module/Directory Name}

## Overview
{2-3 sentences — what this module does, its role in the system, key design decisions.}

## Architecture

Suggested Documentation

{Documentation suggestion — see coordinator behavior}

**Guidelines:**
- Include Mermaid diagrams (component, sequence, state)
- Cover all aspects: architecture, business, data, state
- Depth proportional to module complexity
- Include quality observations from auditors

# {Feature/System} — Business Overview

## What Does It Do?
{Plain language explanation — no technical jargon.}

## Who Uses It?
| Actor | What They Do |
|-------|-------------|
| {role} | {their interaction with the system} |

## Key Business Processes

### {Process 1}
**When:** {trigger in business terms}
**What happens:**
1. {step in business language}
2. {step}
3. {step}
**Result:** {outcome}

## Business Rules

    S -->|charges| P[Payment Provider]
    S -->|ships via| W[Warehouse]

Limitations & Constraints

• {business limitation 1}
• {business limitation 2}

**Guidelines:**
- Zero code references
- Business language only

```markdown
## Question: {User's Question}

### Answer
{Direct, concise answer to the question.}

### Details
{Supporting explanation with evidence from code.}

Guidelines:

• Answer the specific question first
• Provide supporting evidence
• Suggest related areas to explore
• Keep focused — don't explain everything
