## What it does

The plugin connects Claude Code to a local Wenlan background daemon at `127.0.0.1:7878`. All memory entries, session logs, and distilled Markdown pages live locally in `~/.wenlan`. On its initial launch, the daemon retrieves a 210 MB embedding model from Hugging Face for hybrid search indexing.

The package includes slash commands like `/capture`, `/recall`, `/brief`, and `/handoff`, alongside a local MCP server runner and two `SessionStart` hooks. One hook assigns the session identifier to the `WENLAN_SESSION` environment variable. The other verifies daemon connectivity and counts unsynced outbox notes with `python3` without interrupting your workflow.

Automatic runtime installation via `/wenlan setup` is limited to macOS on Apple Silicon chips. On other operating systems, you must configure the background components manually by following the project documentation.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install origin@claude-community
```

## When to use it
- retain architecture choices and takeaways across Claude Code sessions
- search past conversational context locally via `/recall`
- generate a structured Markdown wiki inside `~/.wenlan/pages/`
- record session debriefs and update project goals using `/handoff`

## Example prompts
- /capture Switched billing service to PostgreSQL 16
- /recall what naming conventions did we establish for database tables?
- /handoff

# Wenlan

A living knowledge base your agents build as they work. What they learn becomes source-cited wiki pages that refresh between sessions, so each new thread starts from your latest work.

Wenlan is local-first. Memories, pages, and session notes live on your machine under `~/.wenlan`, served by a small local daemon. Nothing in this plugin is stored by Anthropic or by the plugin itself.

## What the plugin contains

- **Skills**: one front door, `/wenlan`, plus `/brief`, `/capture`, `/recall`, and `/handoff`. Setup, notes, distill, wiki, lint, curate, and forget are reached by saying them after `/wenlan` and stay out of the slash menu. Each skill talks to the local daemon over HTTP on `127.0.0.1:7878`.
- **One local MCP server** (`wenlan`), started by `plugin/scripts/wenlan-mcp-runner.sh`. It exposes memory tools (capture, recall, brief, distill, and friends) to Claude Code and Cowork. Claude chat on the web ignores local MCP servers.
- **Two `SessionStart` hooks.** `plugin/hooks/session-context.sh` reads the session id Claude Code passes it, exports `WENLAN_SESSION=claude-code:<id>` for the commands Claude runs, and prints one line so Claude can pass that session when it saves a memory, note, or handoff; Wenlan then shows which conversation a memory or note came from. It makes no network call. `plugin/hooks/check-daemon.sh` probes the local daemon, tells a running daemon that Claude Code is connected (the same `POST /api/agents` the app sends when you connect a tool there, so Claude's first recall already sees your pages; a tool you changed or turned off in Connections stays as it is), and prints at most a few lines: a reminder if the daemon is not running, a count of handoff notes waiting to sync (from the local `wenlan outbox status` command, parsed with `python3`), and a notice if the daemon and plugin versions have drifted apart. It never blocks a session and never installs anything.

## Setup

Install from the Claude directory, or from the Claude Code marketplace:

```text
/plugin marketplace add wenlan-app/wenlan
/plugin install wenlan@7xuanlu-wenlan
```

Then restart Claude Code and run `/wenlan`. When Wenlan is not ready yet it starts setup, which installs the local runtime if it is missing (macOS Apple Silicon; elsewhere it links the install guide), configures local memory, verifies the MCP round trip, and prints "Wenlan ready". After that, `/capture <something to remember>` or `/brief` is the daily loop.

The first run downloads an embedding model of roughly 210 MB, so allow a few minutes.

## What it runs and where data goes

Everything the plugin does is listed here so you can decide whether to install it.

| Component | What it runs | Network destination |
|---|---|---|
| Skills and MCP server | Read and write memories, pages, and session notes | `127.0.0.1:7878` (the local Wenlan daemon on your machine) |
| `/wenlan` setup | When the runtime is missing, runs `npx -y wenlan@<pinned version> setup` (macOS Apple Silicon). On other platforms it stops and points you to the install guide | `registry.npmjs.org` (npm package `wenlan`), which downloads release binaries from `github.com/wenlan-app/wenlan/releases` (GitHub serves the files from `objects.githubusercontent.com`) |
| MCP runner fallback | If no local `wenlan-mcp` binary exists, runs `npx -y wenlan-mcp@<pinned version>` | `registry.npmjs.org` (npm package `wenlan-mcp`) |
| `SessionStart` hooks | One health probe of the local daemon, plus the local outbox and version checks above | `127.0.0.1:7878` only (the session hook makes no network call) |
| Local daemon, first start | Downloads the search embedding model (about 210 MB, `Qdrant/bge-base-en-v1.5-onnx-Q`) once | `huggingface.co`. No memory content is sent. If a Hugging Face token is already saved on the machine, the download library attaches it |
