LoreRoom

Your Claude Code Telegram bot — but it remembers.

📖 Read the story — why inbound Telegram messages skip every hook

中文版 → README.zh-TW.md

A private, encrypted room that remembers every conversation with your Claude Code Telegram bot — both sides — so it never forgets.

You chat with Claude Code from your phone through the official Telegram plugin. But every Claude Code session is amnesiac: restart it and the whole conversation is gone. LoreRoom captures both sides of that Telegram conversation into a single, whole-file-encrypted SQLite database and hands it back to Claude as searchable memory.

So you can ask your bot:

You: what did I ask you to do last night? Bot: (searches LoreRoom) You asked me to fix the crawler retry logic and send you the diff…

Local-first. No cloud, no extra API keys, it never touches your bot token.

Why LoreRoom exists (and why it's reliable)

The Claude Code Telegram plugin delivers your incoming messages to Claude through an internal channel push — not through any hook. Worse, when Claude is busy those messages queue invisibly, and if the bot never replies they're simply gone. So the obvious approaches (hooks, reading the transcript) silently lose your messages.

LoreRoom captures at the plugin's source, the instant a message arrives from Telegram:

• Inbound — the moment Telegram delivers it, before any queue, regardless of whether Claude is busy, crashed, or never replies.
• Outbound — whenever the bot sends a reply.

Both are written to a small spool file that an ingester drains into the encrypted database. Nothing is lost — even when your bot is unresponsive. (Messages that were stuck while the bot was busy get captured the moment it restarts and re-fetches them.)

No Claude Code hooks are used, so LoreRoom never interferes with your other Claude Code work.

Before you start — what you need

LoreRoom adds memory to an existing Claude Code Telegram bot. So you first need that bot working. If you can already chat with your bot from Telegram, skip to Install. Otherwise, set this up once (~5 minutes):

1. Node.js 20 or newer. Check with node -v. If missing, get it from nodejs.org.

2. Claude Code — Anthropic's command-line tool. See the install guide.

3. A Telegram bot connected to Claude Code:

1. In Telegram, open a chat with @BotFather, send /newbot, follow the prompts, and copy the bot token it gives you (a long string).
2. In Claude Code, install the official Telegram plugin, then configure it with your token: /telegram:configure <your-bot-token>.
3. Link your account: send your bot any message in Telegram — it replies with a pairing code — then run /telegram:access pair <code> in Claude Code.
4. Start a bot session: claude --channels plugin:telegram@claude-plugins-official, then send your bot "hi" in Telegram. It should reply.

Once "hi" gets a reply, your bot works. Now give it memory with LoreRoom 👇

Scope: LoreRoom only works with Claude Code + the official Telegram plugin (it is not a general Telegram bot framework). It captures by patching the plugin — one idempotent command you re-run after plugin updates. See Why patch the plugin.

Install

git clone https://github.com/fenghaochang/LoreRoom.git && cd LoreRoom
npm install
npm run build
node dist/cli.js init        # creates config.json + a fresh encryption key, prints the next steps
node dist/patch-plugin.js    # patches the Telegram plugin to capture in + out
# register the recall server (it also auto-drains the spool):
claude mcp add --scope user loreroom -- "$(command -v node)" "$PWD/dist/mcp-server.js"

Then restart your bot session (claude --channels …) so it loads the patched plugin. Done — every Telegram message is now captured automatically.

Node version note: the encrypted-SQLite native module is ABI-bound to one Node version, and init pins the exact node that ran it. If you later upgrade or remove that Node, re-run npm install && npm run build and re-register.

Verify

1. Send your bot a message on Telegram.
2. Ask Claude (in any session) to call get_recent_context with hours: 1 — you'll see your message with the correct time and sender, even if the bot never replied.
3. Ask it to search_tg_history for a keyword from that message — it comes back.

How you use it day to day

Nothing to do — that's the point. Once it's set up, just chat with your bot normally. Every message, both yours and the bot's, is saved automatically.

When you want it to remember something, just ask in plain language:

"what did we decide about the database yesterday?" "what did I send you last night?" "find where I mentioned the API key"

The bot searches its own memory and answers. You never run a command — it calls the search tools for you behind the scenes.

Two things to keep in mind:

• Keep a bot session running (claude --channels …). If it stops, restart it — messages that arrived while it was down are captured when it comes back.
• After you update the Telegram plugin, re-run node dist/patch-plugin.js once to re-apply the patch (it's a no-op if already patched).

Why patch the plugin

There is no hook and no on-disk record for inbound Telegram messages, so the only reliable capture point is inside the plugin itself. The patch is tiny — a helper plus two one-line calls at the plugin's inbound and outbound choke points — and idempotent (running it twice is a no-op). Plugin updates overwrite it, so re-run node dist/patch-plugin.js after an update.

Self-contained

Everything LoreRoom owns lives inside this project folder:

• config.json — your settings + encryption key (git-ignored, chmod 600, created by init)
• data/memory.sqlite — the encrypted database (git-ignored)

The spool is a short-lived plaintext file in the plugin's own ~/.claude/channels/telegram/ state dir (mode 0700), drained continuously and deleted.

Configuration (config.json)

Draining the spool

The MCP server drains on startup, every 20s, and before each query — so whenever any Claude Code session is open, capture flows into the DB automatically. For draining independent of sessions:

node dist/cli.js ingest   # drain once
node dist/cli.js watch    # drain continuously (good for launchd/cron)

MCP tools Claude can call

• get_recent_context({ hours, chat_id? }) — messages from the last N hours.
• search_tg_history({ keyword, chat_id? }) — full-text search across all history (FTS5 trigram, works for CJK; LIKE fallback for short keywords).

Both return each hit with timestamp, sender, role, chat id, and text.

Security & encryption boundary

• LoreRoom never handles your Telegram bot token — that belongs to the plugin. There is no token to leak here.
• The only secret is the 32-byte encryption key in config.json (git-ignored, chmod 600) — never committed, never logged.
• The database is encrypted as a whole file (SQLCipher / AES-256). Copying data/memory.sqlite to another machine is useless without the key.
• This is at-rest encryption of the local DB — NOT Telegram end-to-end encryption. It changes nothing about Telegram itself. Decryption happens only locally, in LoreRoom's own processes; the key is never given to Claude and never crosses a network.
• Protects against: the DB file being copied off the machine / a backup leak. Does not protect against: someone who can already read your account's files on this machine (the key sits next to the DB by design). The spool is briefly plaintext until drained.
