living-memory-engine: Instructions file for Claude Code

CLAUDE.md

living-memory-engine CLAUDE.md is an instructions file for Claude Code from v1b3x0r/living-memory-engine. It costs 2,370 tokens per session, scanned A, a copy of living-memory-engine AGENTS.md, Apache-2.0.

Project instructions for a TypeScript chat application that maintains a long-lived conversation with a persona by storing, reducing, and retrieving memories. TDD means test-driven development: planning or writing tests as part of the design process.

In plain words
What is it for?
Use them to understand the web app, memory engine, and mobile area, find the right commands and files, and resume work after a previous session.
Why use it?
They explain the repository's three parts, where active work happens, and where session notes, design documents, and test plans are kept.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions Codex.

This is v1b3x0r/living-memory-engine's own configuration. It tells Claude Code how to work on living-memory-engine itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything living-memory-engine configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is cd ../web && npm install && npm run dev # → http://localhost:5173 (Vite).

Reuse

Borrowing it

Nothing to install: this file belongs to v1b3x0r/living-memory-engine. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

living-memory-engine CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

94% identical to living-memory-engine AGENTS.md — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

A personal living-memory chat: talk forever to an entity (the star persona is เชียงใหม่, a province that senses the real world and greets you first). Instead of stuffing the context window, a TypeScript memory engine decays / consolidates / crystallizes memories so a single thread never overflows — each turn the LLM sees only a small retrieved working set. The thesis driving current work: for a local-first entity, self-awareness (knowing its own state) > raw model intelligence.

Side project of the Viibe World OS workspace (not the HomeLog sprint). Resume context lives in NEXT-SESSION.md; design specs and TDD plans live under docs/superpowers/{specs,plans}/.

Three parts (one git repo)

Dir Status What
web/ ACTIVE — all current work Plain Vite + vanilla TypeScript app (no React/framework) + uicp drawer. The product.
engine/ Stable substrate @nature-labs/living-memory-engine — framework-agnostic TS memory engine. Consumed by web/ via file:../engine (its prebuilt dist/).
mobile/ FROZEN — do not touch Old Expo/React Native app. Superseded by web/. Not deleted; not maintained.

Commands

First-time setup — the engine must be built before the web app can import it (web/ links the engine's prebuilt dist/ via file:../engine, and dist/ is gitignored):

cd engine && npm install       # the `prepare` hook builds dist/ automatically on install
cd ../web && npm install && npm run dev   # → http://localhost:5173 (Vite)

Then, working in web/ (the app):

cd web && npm test             # vitest (run once)
cd web && npx vitest run test/selfstate.test.ts   # a single test file
cd web && npx tsc --noEmit     # typecheck (expect 0 errors)

The engine has its own suite:

cd engine && npm test          # vitest
cd engine && npm run build     # tsc -p tsconfig.build.json → dist/   (REQUIRED after editing engine/src — see below)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
