Repomemory

npx repomemory go

The Problem

Every time you open a project with Claude Code, Cursor, Copilot, or any AI coding agent:

• It re-discovers your architecture from scratch
• It proposes changes that were already debated and rejected
• It re-introduces bugs that were already fixed

Your CLAUDE.md / .cursorrules helps, but it's static and gets stale.

The Solution

.context/├── index.md              ← Quick orientation (loaded every session)├── facts/                ← Architecture, database, deployment├── decisions/            ← "We chose Drizzle over Prisma because..."├── regressions/          ← "This broke before. Here's what happened."├── preferences/          ← Your coding style — follows you across all repos├── sessions/             ← Auto-captured AI session summaries└── changelog/            ← Monthly git history syncs

Facts tell agents how things work. Decisions prevent re-debating. Regressions prevent re-breaking. Preferences teach agents how you code.

Quick Start

With an API key (Claude Code, terminal workflows)

npx repomemory go

One command: sets up global profile, creates .context/, configures Claude Code + Cursor, runs AI analysis, prints CLAUDE.md instructions.

With Cursor (no API key needed)

npx repomemory setup cursor

This installs everything Cursor needs:

• MCP server in ~/.cursor/mcp.json (auto-starts repomemory in every project)
• Rules in .cursor/rules/repomemory.mdc (teaches Cursor's AI to use context)
• 6 commands in .cursor/commands/ (run with / in Cursor chat)

Then in Cursor chat, type:

/repomemory-analyze

Cursor's own AI scans your repo and populates .context/ via the MCP tools. No external API key required — your Cursor subscription handles it.

Available Cursor commands:

Guided wizard

npx repomemory wizard

Walks through provider selection, tool integration, and first analysis. If no API keys are detected, offers a "None — I use Cursor" option that skips external analysis entirely.

Non-interactive (CI-safe)

npx repomemory go --yes --provider anthropic --embedding-provider gemini --max-files 80

No prompts when --yes / --defaults / --no-prompt is used.

MCP Server — Agents With Real Memory

The real power is the MCP server. When configured via repomemory setup claude, it auto-starts with Claude Code and gives agents 7 tools:

Agent: "Let me orient myself in this project..."→ context_auto_orient()→ Returns: project overview, preferences, recent sessions, recent changes
Agent: "Let me search for context about the auth flow..."→ context_search("authentication flow")→ Auto-routes to facts/ category, returns compact results
Agent: "I found a race condition. Let me record this."→ context_write(category="regressions", filename="token-refresh-race", content="...")→ Persisted. Detects if it supersedes an existing entry.

Sessions are auto-captured on shutdown. Zero config — repomemory setup claude handles everything.

Supported Tools

Cursor users: You don't need any API key. Run npx repomemory setup cursor, then use /repomemory-analyze in Cursor chat. Cursor's AI does the analysis using the MCP tools — whatever model Cursor is using (it can even switch models mid-task).

Supported Providers

Embeddings (optional, for semantic search): Gemini text-embedding-004 (free, default) or OpenAI text-embedding-3-small. Auto-detected from available API keys.

Configuration

.repomemory.json in your repo root (all fields optional):

{  "provider": "anthropic",  "model": "claude-sonnet-4-6",  "embeddingProvider": "gemini",  "hybridAlpha": 0.5,  "maxFilesForAnalysis": 80,  "enableGlobalContext": true}

Custom ignorePatterns and keyFilePatterns are additive — they extend built-in defaults, not replace them.

Why Not Just CLAUDE.md?

repomemory doesn't replace CLAUDE.md — it complements it. CLAUDE.md is for instructions and rules. .context/ holds the knowledge that grows over time.
