Forceful operating rules for using LycheeMem as the primary structured long-term memory path inside OpenClaw.

Choose how to use this skill

You do not need every option. Choose the path your AI client supports. The stable page stays the same; versioned files are immutable.

1. Native installer

This listing has no registered native installer command. Use the complete package or source fallback below, depending on what your client supports.

Do not guess an installer command or replace an existing version without reviewing the diff.

2. Complete package recommended

Download the ZIP when available. It includes SKILL.md plus the references, security notes and version metadata.

No complete ProSkills package is published for this listing yet.

3. Prompt-only

Copy the prompt above when the agent can read the stable page or when you want to adopt the workflow without installing a skill.

Need only the instruction file?

Download SKILL.md only if your client requires a single file. The complete ZIP is safer for a full installation because it preserves the references and release context.

No path installs or executes anything by itself. Your agent still needs access to the project files. Before updating, compare the installed version and review the diff.

LycheeMemory is a compact memory framework for LLM agents. It starts from efficient conversational memory—through structured organization, lightweight consolidation, and adaptive retrieval—and gradually extends toward action-aware, usage-aware memory for more capable agentic systems.

⚡ Quick Start

Prerequisites

  • Python 3.9+
  • An LLM API key (OpenAI, Gemini, or any litellm-compatible provider)

Installation

Install the core package:

pip install lycheemem

Recommended install with the default transformer memory reranker:

pip install "lycheemem[rerank]"

The rerank extra adds PyTorch / Transformers runtime dependencies. With it installed, LycheeMemory enables the hosted LycheeMem/reranker checkpoint by default. Without the extra, the core memory system still works and reranki
