🧠 RetainCode — Less AI Hallucinations

Give your AI the right context. Get better code.

RetainCode indexes your codebase locally and lets AI tools (Copilot, Claude, etc.) find the exact code they need — no guessing, no hallucinating, no data leaving your machine.

⚡ Get Started in 3 Steps

1. Install the extension from the VS Code Marketplace

2. Open the RetainCode sidebar (🧠 icon in the Activity Bar) → Click ▶ Turn On

3. Press Ctrl+Shift+H and search your code in plain English

Done. Your codebase is now indexed and searchable.

What It Does

Feature	How
Semantic Search	`Ctrl+Shift+H` — find code by meaning, not keywords
CodeLens	"Find similar" and "Search references" above every function
Hover Context	Hover any symbol → see related code from other files
TODO Tree	Sidebar shows all TODO/FIXME/HACK comments
Integrations	Connect Jira, Slack, GitHub from the sidebar

Click the 🧠 icon in the Activity Bar:

🧠 RetainCode
├── ▶ Turn On              ← starts indexing + MCP server
├── 🔍 Semantic Search      ← search by meaning
├── 📊 Show Status          ← indexed files, chunks, cache
├── 🔄 Reindex Workspace    ← rebuild from scratch
├── 🗑️ Clear Index           ← delete everything
└── ⚙️ Settings              ← configure options

All features are disabled until you turn it on — no surprise background tasks.

Save Tokens & Reduce Hallucinations

These settings give your AI tighter, more relevant context:

Setting	Recommended	Why
Auto Index	`false`	Index only when you choose
Min Score	`0.75`	Fewer but more accurate results
CodeLens	`true`	See related code at a glance
Hover	`true`	Quick context without searching

Add to your settings.json:

{
  "codegraph.codeLens.enabled": true,
  "codegraph.hover.enabled": true
}

How It Works

Turn On → starts the MCP server as a background process
Indexes your files using AST parsing (Tree-sitter) + local embeddings (384-dim)
Searches combine semantic similarity + keyword matching
Everything stays local — no API calls, no cloud, 100% private

Settings Reference

Setting	Default	Description
`codegraph.codeLens.enabled`	`true`	Show CodeLens above functions
`codegraph.hover.enabled`	`true`	Show related code on hover
`codegraph.todos.tags`	`TODO,FIXME,...`	Tags to scan
`codegraph.indexing.maxFileSize`	`1 MB`	Max file size to index
`codegraph.indexing.excludePatterns`	`[]`	Globs to skip
`codegraph.jira.baseUrl`	—	Jira URL
`codegraph.slack.botToken`	—	Slack Bot Token
`codegraph.github.token`	—	GitHub PAT

FAQ

Does it send my code anywhere? No. Everything runs locally on your machine.

How long does indexing take? Small projects: ~10s. Large projects (10K+ files): 1–2 minutes.

What languages work? TypeScript, JavaScript, Python, and any text file. More parsers coming.

Do I need an API key? No. Embeddings are generated locally. Jira/Slack/GitHub tokens are optional extras.
