Page Action Cache - OpenClaw Extension

An OpenClaw extension that provides in-memory page snapshot caching with LRU eviction (max 50 entries) and TTL (5-minute expiry). Version 2026.21.1 ships TypeScript types, uses ESM only, and targets Node.js 22+. It exports three tools (page_snapshot_cache, page_cache_stats, page_cache_clear) for caching page snapshots and role references. Unlike generic caches, this integrates natively with OpenClaw's plugin SDK and AI-driven Web UI, offering hit-rate statistics and automatic cleanup. The cache is not persistent and resets on process restart.
