It's great — until the session restarts and the bot forgets the entire conversation. Ask "what did we decide yesterday?" and it has no idea.</p> <h2> The surprising part: inbound messages don't trigger any hook </h2> <p>My first instinct was a <code>UserPromptSubmit</code> hook to log every message. It never fired for Telegram messages.</p> <p>Inbound Telegram messages are delivered to Claude through an <strong>internal channel push</strong> — not through any of Claude Code's hooks. Worse, when the bot is busy they <strong>queue invisibly</strong>, and if it never replies they can be lost. So the two "obvious" approaches — hooks and scraping the transcript — both silently drop messages.</p> <p>The only reliable capture point is <strong>inside the plugin itself</strong>, the moment a message arrives.</p> <h2> What I built: LoreRoom </h2> <p>It patches the Telegram plugin at its source to capture <strong>both directions</strong> the instant each message arrives — even if the bot is busy, crashed, or never replies — into a <strong>whole-file-encrypted SQLite DB</strong> (SQLCipher). Recall is handed back to Claude as two MCP tools:</p> <ul> <li> <code>get_recent_context(hours)</code> — the last N hours</li> <li> <code>search_tg_history(keyword)</code> — full-text search over everything (FTS5 trigram, works for CJK too)</li> </ul> <p>Local-only; never touches your bot token.<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>You &lt;-&gt; Telegram ──(patched plugin)──&gt; spool ──&gt; encrypted SQLite ──(MCP)──&gt; Claude recalls </code></pre> </div> <p>Now I can ask my bot "what did I send you last night?" and it actually answers.</p> <h2> On encryption </h2> <p>This is <strong>at-rest encryption of the local DB</strong>, not Telegram E2E. It protects the DB file if it's copied off the machine; the key lives in a git-ignored, <code>chmod 600</code> config and is never given to Claude or sent over a network.</p> <h2> Try it </h2> <p>MIT-licensed: <a href="https://github.com/fenghaochang/LoreRoom" rel="noopener noreferrer">https://github.com/fenghaochang/LoreRoom</a><br> Stack: TypeScript, better-sqlite3 (SQLCipher), MCP SDK, FTS5.
