mnemos CLAUDE.md

mnemos CLAUDE.md is an instructions file for Claude Code from anthony-maio/mnemos. It costs 930 tokens per session, scanned A, original, MIT.

Repository instructions for Mnemos, a Python library that gives language models several memory mechanisms and an MCP server for agent integration.

In plain words
What is it for?
Use them to install the project, run its pytest tests, format code, and work on its memory modules, command-line tools, or MCP integration.
Why use it?
They explain the code layout, installation, tests, examples, and development commands for the project.

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

mnemos 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.

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

Project

mnemos — a biomimetic memory architecture library for LLMs. Implements five neuroscience-inspired memory mechanisms: surprisal-gated encoding, mutable RAG, affective routing, sleep consolidation, and spreading activation. Python 3.10+, MIT licensed, alpha (0.1.0).

Repository Layout

mnemos/        → Source package
  modules/     → Five biomimetic memory modules
  utils/       → LLM, embedding, and storage provider abstractions
  cli.py       → Shell CLI for hooks and automation
  mcp_server.py → MCP server for agent integration
tests/         → pytest suite (3 files: engine, modules, types)

Development Commands

# Install (editable + dev deps)
pip install -e '.[dev]'

# Run all tests
pytest

# Run a single test file
pytest tests/test_engine.py

# Run a single test by name
pytest tests/test_modules.py -k "test_surprisal"

# Format

# Type check (strict mode)
mypy .

# Run MCP server (stdio transport)
mnemos-mcp

# CLI commands (shell-friendly, defaults to SQLite)
mnemos-cli store "some content"
mnemos-cli retrieve "query" --top-k 5
mnemos-cli consolidate
mnemos-cli stats

Tests use MockLLMProvider + SimpleEmbeddingProvider + InMemoryStore — no external services needed. Async tests auto-detected via asyncio_mode = "auto".

Architecture

MnemosEngine (engine.py) orchestrates five modules through three paths:

  • Encode (process()): Input → SurprisalGate (filter novelty) → AffectiveRouter (tag emotion) → Store + SleepDaemon buffer
  • Decode (retrieve()): Query → AffectiveRouter (classify) → SpreadingActivation (graph propagation) → AffectiveRouter (re-rank) → MutableRAG (reconsolidate stale facts) → Results
  • Consolidate (consolidate()): SleepDaemon extracts semantic facts from episodic buffer → writes to store → prunes

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.

mnemos CLAUDE.md is an instructions file published in the GitHub repository anthony-maio/mnemos (27 stars, last pushed 5mo ago), licensed MIT. It adds 930 tokens to every session, about $0.0047 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
