Plugin platform for long-running AI agents
LightMem2 separates agent capabilities into reusable plugins that run across multiple hosts, so you only build each feature once.
Available plugins
Each plugin provides a distinct capability. Install what you need, skip what you don't.
| Plugin | Capability | Status | Hosts |
|---|---|---|---|
| TokenPilot | Cache-aware context management | Stable | OpenClawCodexClaude Code |

TokenPilot: cache-efficient context
TokenPilot is the first official LightMem2 plugin. It reduces token usage and cost in long-running agent sessions through stable-prefix rewriting, context reduction, and lifecycle-aware eviction.
🔒 Stable Prefix
Rewrites developer-level context into a cache-stable form, dramatically improving cache hit rates across turns.
✂️ Context Reduction
Trims oversized tool output before it pollutes later turns, keeping the context window lean without losing signal.
🗑️ Context Eviction
Limits how much old context is carried forward as sessions grow, preventing unbounded context bloat.
📊 Reports & Visuals
Built-in inspector shows token savings, cache efficiency, and session metrics in real time.
