KongCode

Graph-backed permanent memory for Claude Code.

Quick start | Architecture | Configuration | Troubleshooting | Development

What it does

KongCode gives Claude Code a persistent, queryable memory that grows with every session. It extracts concepts, causal chains, corrections, preferences, decisions, and skills from conversations automatically — then retrieves them with a multi-stage pipeline (BGE-M3 vectors → learned ACAN scoring → cross-encoder reranking, 98.2% R@5) backed by a SurrealDB graph running locally. After enough sessions, the agent earns an emergent identity (soul graduation) grounded in its actual working history.

Capability	Stock Claude Code	With KongCode
Memory	File-based, per-project, manual	Graph DB, cross-session, automatic
Context window	Sliding, lost on `/clear` or session end	Retrieval-augmented from prior turns and concepts
Knowledge extraction	None	Concepts, causal chains, monologues, corrections, preferences, artifacts, decisions, skills, reflections
Procedural memory	None	Skills mined from successful workflows, surfaced when preconditions match
Retrieval quality	None (no memory to retrieve)	Vector search → ACAN reranker → cross-encoder rerank → graph expansion (98.2% R@5 on LongMemEval)
Identity	Stateless on every turn	Earned soul after a graduation gate (volume + quality thresholds)

Quick start

Install the plugin, set up the system prompt, and open a session. The daemon provisions SurrealDB, the embedding model, and everything else on first run.

Prerequisites

Tool	When required
git	Always (Claude Code uses it to clone the marketplace repo)
Node.js >= 18 + npm	Only for the JS fallback path. Most users on linux-x64/arm64, macOS x64/arm64, win-x64 get the SEA binary and don't need Node.

Quick installs (only if you need Node + git for the fallback path):

macOS: brew install node git
Windows (PowerShell, elevated): winget install OpenJS.NodeJS.LTS Git.Git then restart your terminal AND Claude Code so the new PATH is picked up.
Linux: distro package manager (apt install nodejs npm git) or nvm.

1. Install the plugin

CLI:

/plugin marketplace add 42U/kongcode
/plugin install kongcode@kongcode-marketplace

VS Code / Cursor / JetBrains

The plugin system is shared across CLI and IDE extensions. Open a Claude Code session in your IDE, then:

Type /plugins and press Enter (shows Manage Plugins)
Go to the Marketplaces tab
Type 42u/kongcode in the input field and click Add
Switch to the Plugins tab
Toggle kongcode@kongcode-marketplace on

2. Set up prompts (before launching Claude Code)

KongCode ships two template files that teach Claude how to use the memory graph. Set both up before your first session.

# Find the plugin cache (installed by step 1)
KONGCODE_DIR=$(ls -d ~/.claude/plugins/cache/kongcode-marketplace/kongcode/* 2>/dev/null | head -1)

# Copy the system prompt (appended every session via CLI flag)
cp "$KONGCODE_DIR/templates/kongcode.txt" ~/.kongcode-prompt.txt
