derp - Backlog

Core

• Multi-server support (per-server config, shared plugins)
• Stable plugin API (versioned, breaking change policy)
• Paste overflow (auto-paste long output to FlaskPaste)
• URL shortener integration (shorten URLs in subscription announcements)
• Webhook listener (HTTP endpoint for push events to channels)
• Granular ACLs (per-command: trusted, operator, admin)

LLM Bridge

Goal: let an LLM agent interact with the bot over IRC in real-time, with full machine access (bash, file ops, etc.).

Architecture

Owner addresses the bot on IRC. A bridge daemon reads addressed messages, feeds them to an LLM with tool access, and writes replies back through the bot. The bot already has owner config ([bot] owner hostmask patterns) to gate who can trigger LLM interactions.

IRC -> bot stdout (addressed msgs) -> bridge -> LLM API -> bridge -> bot inbox -> IRC

Approach options (ranked)

1. Claude Code Agent SDK (clean, non-trivial)

   • Custom Python agent using anthropic SDK with tool_use
   • Define tools: bash exec, file read/write, web fetch
   • Persistent conversation memory across messages
   • Full control over the event loop -- real-time IRC is natural
   • Tradeoff: must implement and maintain tool definitions

2. Claude Code CLI per-message (simple, stateless)

   • echo "user said X" | claude --print --allowedTools bash,read,write
   • Each invocation is a cold start with no conversation memory
   • Simple to implement but slow startup, no multi-turn context
   • Could pass conversation history via system prompt (fragile)

3. Persistent Claude Code subprocess (hack, fragile)

   • Long-running claude process with stdin/stdout piped
   • Keeps context across messages within a session
   • Not designed for this -- output parsing is brittle
   • Session may drift or hit context limits

Bot-side plumbing needed

• --llm CLI flag: route logging to file, stdout for addressed msgs
• _is_addressed(): DM or nick-prefixed messages
• _is_owner(): only owner hostmasks trigger LLM routing
• Inbox file polling (/tmp/llm-inbox): bridge writes <target> <msg>
• llm-send script: line splitting (400 char), FlaskPaste overflow
• Stdout format: HH:MM [#chan] <nick> text / HH:MM --- status
• Only LLM-originated replies echoed to stdout (not all bot output)

Previous attempt (reverted)

The --llm mode was implemented and tested (commit ea6f079, reverted in 6f1f4b2). The stdout/stdin plumbing worked but Claude Code CLI cannot act as a real-time daemon -- each tool call is a blocking round-trip, making interactive IRC conversation impractical. The code is preserved in git history for reference.
