decision-history（决策历史）

Decision History Dashboard

Visualize how OrchestKit evolved with Claude Code versions, understand WHY decisions were made, and track best practices adoption.

Overview

• View architecture decisions chronologically
• Track Claude Code version evolution (2.1.0 → 2.1.16+)
• Understand rationale behind each decision
• Generate Mermaid timeline diagrams for docs
• Query decisions by category, CC version, or date range

Quick Start

# List recent decisions
node hooks/bin/decision-history.mjs list

# Show decisions for specific CC version
node hooks/bin/decision-history.mjs list --cc-version 2.1.16

# Generate Mermaid timeline
node hooks/bin/decision-history.mjs mermaid --output timeline.md

# Filter by category
node hooks/bin/decision-history.mjs list --category security

# Show last 30 days
node hooks/bin/decision-history.mjs list --days 30

# View statistics
node hooks/bin/decision-history.mjs stats

# Search decisions
node hooks/bin/decision-history.mjs search "typescript hooks"

Data Sources

Decisions are aggregated from multiple sources (priority order):

CLI Commands

# List decisions with filters
decision-history list [--cc-version VER] [--category CAT] [--days N] [--limit N]

# Show decision details
decision-history show <decision-id>

# Display timeline view
decision-history timeline [--group-by cc_version|category|month]

# Show statistics
decision-history stats

# Generate Mermaid diagram
decision-history mermaid [--output FILE] [--full] [--group-by FIELD]

# Sync from all sources (refresh cache)
decision-history sync

# Search decisions
decision-history search <query>

Decision Schema

Each decision includes:

interface Decision {
  id: string;              // e.g., "4.28.0-architecture-1"
  date: string;            // ISO date: "2026-01-21"
  summary: string;         // Brief description
  rationale?: string;      // Full explanation
  ccVersion?: string;      // e.g., "2.1.16"
  pluginVersion?: string;  // e.g., "4.28.0"
  category: string;        // e.g., "architecture", "security"
  impact: 'high' | 'medium' | 'low';
  status: 'proposed' | 'implemented' | 'deprecated' | 'superseded';
  source: 'changelog' | 'session' | 'coordination' | 'mem0';
  bestPractice?: string;   // Related best practice
  entities?: string[];     // Related concepts
}

Implementation

This skill is implemented in TypeScript as part of the hooks infrastructure:
