I Built a Tool That Made Claude 122% Better at Understanding My Codebase

The Problem That Was Driving Me Insane

Every Claude Code session:

Me: "Add authentication to the API"
Claude: *suggests Express.js*
Me: "We use Gin. I told you this yesterday."
Claude: "I apologize for the confusion..."

I timed it. 10+ minutes per session re-explaining:

Why we chose PostgreSQL over MongoDB
Our file structure conventions
That we use Zustand, not Redux
The deployment constraints

My AI assistant had amnesia. Every. Single. Time.

The Fix: Give AI Permanent Memory

I built TaskWing — a CLI that extracts your architectural decisions and exposes them to AI via MCP.

brew install josephgoksu/tap/taskwing

taskwing bootstrap   # Scans your codebase
taskwing mcp         # Exposes to Claude/Cursor

That's it. Your AI now remembers your architecture permanently.

The Results (Measured, Not Claimed)

I ran the same 5 architecture questions against Claude with and without TaskWing:

Metric	Without	With TaskWing
Avg Score	3.6/10	8.0/10
Pass Rate	0%	100%

+122% improvement. Full methodology here.

Note: 122% = (8.0 - 3.6) / 3.6. The score more than doubled from baseline.

What It Captures

.taskwing/memory/
├── memory.db          # SQLite: decisions, patterns, constraints
└── index.json         # Searchable cache

Examples of what gets extracted:

Decisions: "Chose Gin over Echo for middleware ecosystem"
Patterns: "All handlers follow internal/handlers/{domain}/ structure"
Constraints: "No ORM - raw SQL only for performance"

Connect to Claude Code

Add to your MCP config:

{
  "mcpServers": {
    "taskwing": {
      "command": "taskwing",
      "args": ["mcp"]
    }
  }
}

Now when you ask Claude anything, it queries your architecture first.

Privacy

Your code never leaves your machine. Everything is local SQLite. No cloud, no telemetry, no API calls to store your data. (3rd party APIs are not related to taskwing)

Built this because I was mass frustrated. If you're mass frustrated too, try it and let me know what breaks.
