+# Leteo
+
+Persistent memory for coding agents: one Rust binary over one SQLite database,
+local-first, no service to sign up to.
+
+Each session opens holding what the project already knows, prompts are kept,
+sub-agent findings are captured before their context is discarded, and a
+compaction is recovered from rather than survived.
+
+## Install
+
+```shell
+claude plugin marketplace add zai-org/zai-coding-plugins
+claude plugin install leteo@zai-coding-plugins
+```
+
+**The plugin carries configuration, not the binary.** Install `leteo` first, or
+the MCP entry and every hook here are commands that are not on `PATH`:
+
+```shell
+curl -fsSL https://raw.githubusercontent.com/asanabrial/leteo/main/scripts/install.sh | sh
+```
+
+`cargo install leteo` and a Windows script are in the
+[project README](https://github.com/asanabrial/leteo#install).
+
+## What it registers
+
+| Event | Command | Effect |
+| --- | --- | --- |
+| `SessionStart` (`startup`, `clear`) | `leteo hook session-start` | Opens the session and hands back the project's recent work, prompts and most relevant memories |
+| `SessionStart` (`compact`) | `leteo hook post-compaction` | Puts back what the compaction took, and clears what had been marked as already shown |
+| `UserPromptSubmit` | `leteo hook user-prompt-submit` | Keeps the prompt, and names a memory worth having in front of you — never the same one twice in a session |
+| `SubagentStop` | `leteo hook subagent-stop` | Captures a sub-agent's Key Learnings, in any of the thirteen languages Leteo speaks |
+| `SessionEnd` | `leteo hook session-stop` | Closes the session |
+
+Alongside them, [`.mcp.json`](.mcp.json) registers the MCP server with the
+`agent` tool profile, so the everyday tools are there from the first message,
+and [`skills/memory`](skills/memory/SKILL.md) carries the protocol that tells
+the agent when to reach for them. Tools without that protocol is the shape that
+measured 0 saves out of 8 tasks.
+
+Every hook is best-effort and bounded: Leteo gives up before Claude Code does,
+and a hook that could not do its work says so rather than failing silently.
+Memory is an assistant, not a gate.
+
+## Alternative to the plugin
+
+`leteo setup claude-code --hooks` writes the same five registrations into
+Claude Code's own settings directly. **Pick one, not both** — registered twice,
+every lifecycle event runs twice, which stored each prompt twice on the machine
+where it was found, 23 identical pairs before anything looked wrong from the
+outside. `leteo setup` looks for an installed bundle and refuses rather than
+adding a second copy.
+
+## Design
+
+The bundle is deliberately thin. Project detection, the stable manual session,
+`<private>` redaction, deduplication, the save reminder and its debounce, and
+the `.leteo/` import all live in the Leteo binary, shared with the CLI, the MCP
+server and every other agent's hooks. These files only say which event maps to
+which command, so there is one implementation to keep correct instead of two.
+
+Which events belong here is not written out twice either: upstream holds one
+list per agent and a guard reads each bundle against it, matchers and deadlines
+included. Written out here and nowhere held, they drift.
+
+## Upstream
+
+Canonical source, issues and the full documentation:
+<https://github.com/asanabrial/leteo>. MIT licensed. Leteo is a
+reimplementation of Engram; that attribution is kept in the project's `NOTICE`.
+
+Leteo also ships a ZCode-targeted bundle upstream, which registers three events
+rather than five because that client fires neither `SubagentStop` nor
+`SessionEnd`. This entry is the Claude Code one, which is what this marketplace
+is for.
