AI code duplication stops here.

Built for Claude Code

The Problem

AI coding assistants are powerful — but they're blind to your codebase. They can't see your existing utilities, your naming conventions, or the function you wrote last week that does exactly what they're about to create from scratch.

The result? Duplicate code. Everywhere.

• A new formatDate() when one already exists in src/utils/
• A second UserService because the AI didn't know about the first
• Inconsistent naming, broken conventions, growing entropy

This isn't an AI problem. It's a visibility problem.

The Solution

AICodeSight generates an architectural metadata layer that makes your codebase visible to AI assistants. It scans your project, catalogs every export, maps dependencies, and produces machine-readable artifacts that AI assistants consult before writing a single line of code.

Your Code → aicodesight init → AI can see everything → No more duplicates

It also installs runtime guards — hooks that intercept AI actions in real-time and block duplication before it happens.

Features

• Inventory & Registry — Catalogs every file, export, and type signature in your project
• Capability Index — Enriched descriptions of what each function does and why it exists
• Duplicate Detection — Finds existing duplicates and resolves canonical locations
• Dependency Mapping — Tracks who imports what, identifies critical files
• Guard Pipeline — Runtime hooks that detect and prevent duplication as AI writes code
• Convention Enforcement — Validates naming patterns, file sizes, and structural rules
• Session Memory — Persists context across AI session compactions
• Pattern Modules — Stack-specific best practices (Expo/React Native, Supabase BaaS, shadcn/Tailwind, .NET Minimal API, TanStack Query)
• CLAUDE.md Generation — Produces structured directives tailored to your project

Quick Start

Step 1: Initialize

npx aicodesight init

AICodeSight detects your project type, analyzes the codebase, and generates the architectural layer. After init, your CLAUDE.md has structure, conventions, and guards — but module descriptions are empty.

Step 2: Enrich

Run an enrichment session: the AI reads your source code, understands each function's purpose, and writes a description for every entry in the capability index. These descriptions are then included in CLAUDE.md, giving Claude full visibility into what your codebase does — not just where things are, but why they exist — reducing the chance of creating duplicate functionality.

claude -m sonnet "Follow the instructions in .claude/enrich-capability-index.md"

Sonnet is recommended for this task — it's cost-effective and the instructions are self-contained.

Step 3 (optional): Semantic Duplication Guard

Install semantic duplication detection — catches similar functions even with different names, using AI embeddings:

npm install @xenova/transformers

Requires enriched descriptions (Step 2) — entries without descriptions are skipped.

Step 4: Update

Regenerate CLAUDE.md so it includes the enriched module descriptions:

npx aicodesight update # without semantic guard
npx aicodesight update --embeddings # with semantic guard (requires step 3)

Ongoing

As your code evolves, run aicodesight update periodically to keep artifacts in sync. New entries will appear without descriptions — run another enrichment session to describe them, then update again to include them in CLAUDE.md.

CLI Commands

aicodesight init

Diagnose the project and generate the full architectural layer.

aicodesight init [directory]

Option	Description	Default
--type <type>	Project type: auto, new, legacy	auto
--hooks <mode>	Guard mode: yes (block), warn (advise), no	warn
--dry-run	Preview without writing files	false
--no-blueprint	Skip architectural blueprint	—
--no-interactive	Skip prompts, use auto-detection	—
--embeddings	Enable semantic duplication guard (requires @xenova/transformers and enriched descriptions)	false

aicodesight audit

Deep analysis of duplication, size, conventions, and progress.

aicodesight audit [directory]

Option	Description	Default
--focus <focus>	What to analyze: duplication, size, naming, all	all
--format <format>	Output: console, md, json	console
--output <file>	Save result to file	—

aicodesight update

Regenerate artifacts from the current code state.

aicodesight update [directory]

Option	Description	Default
--only <target>	What to update: claude-md, inventory, duplicates, hooks, registry, memory, all	all
--dry-run	Preview without writing files	false
--embeddings	Enable semantic duplication guard (requires @xenova/transformers and enriched descriptions)	false
