A memory store for LLM agents that gets better the more you use it . Hybrid BM25 + dense retrieval, cross-encoder reranking, clustered retrieval-induced forgetting (RIF). Every retrieval teaches it which entries are chronic distractors — no fine-tuning, just bookkeeping (Anderson, 1994). Install 1. Install the CLI Homebrew installs the lethe CLI: For the standalone CLI only, use Cargo on any platform with a Rust toolchain: Prebuilt CLI bundles are also available from GitHub Releases. Verify the installation, then index and search the current project's Claude Code, Codex, and Oh My Pi transcripts: Transcript discovery uses /.claude , /.codex , and /.omp/agent by default and honors each agent's directory override environment variables. 2. Add a coding agent The CLI works on its own. Install a plugin only if you want recall and recall-global available directly inside a coding agent. Claude Code Recall via skills — lethe indexes your Claude Code transcripts directly and writes nothing into your repos. See plugins/claude-code/README.md. Codex CLI Then run codex , open /plugins , and install lethe — it wires the recall / recall-global skills into Codex automatically. See plugins/codex/README.md. Oh My Pi Restart omp to load the recall / recall-global skills and the background index freshness hook. See plugins/omp/README.md. Cross-project search and periodic compaction are also available from the CLI: Python Node Bench","default_branch":null,"files":null,"tree":[],"storefront":"/r/teimurjan","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/teimurjan/lethe/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
