Add channel context for new conversations

[alexknowshtml]

Summary

When a new thread is created from an @mention, fetch the last 10 messages from the channel to give Claude context about what was being discussed.

How Andy Does It

In bot.ts lines 410-415:

const CONTEXT_MESSAGE_COUNT = 10;

const recentMessages = await message.channel.messages.fetch({ limit: CONTEXT_MESSAGE_COUNT });
const recentContext = recentMessages
    .filter(m => m.id !== message.id && m.id !== statusMessage.id)
    .map(m => `${m.author.username}: ${m.content}`)
    .reverse();

This is sent to Andy Core as recentContext in the payload.

Why This Matters

• User @mentions bot in the middle of a conversation
• Without context, Claude only sees the @mention
• With context, Claude knows what people were discussing

Not Redundant With --resume

• recentContext = channel history BEFORE the thread ("what was being discussed?")
• --resume = thread history INSIDE the session ("continue our conversation")

Implementation for Cord

1. Add CONTEXT_MESSAGE_COUNT = 10 constant
2. In new mention handler, fetch recent messages
3. Format as username: content array
4. Pass to Claude as part of the prompt or prepended context

Priority

Medium - improves conversation quality for new threads
