v0.8.0

Discord-friendly formatting

• System prompt now instructs Claude to avoid markdown tables (Discord cannot render them)
• Two alternative comparison formats: bold key-value lines (default) and code block aligned columns (data-dense)
• Applied to both SYSTEM_PROMPT and RESUME_SYSTEM_PROMPT

v0.7.0 — File Attachments

What's New

File attachment support

Send any file in Discord — images, code, PDFs, documents — and Claude Code will read it.

• Type-agnostic design: no per-format handling, Claude Code decides how to process each file via its Read tool
• 10 MB per-file size limit
• Temp files auto-cleaned after response

Full Changelog: v0.6.0...v0.7.0

v0.6.0 — Resume Local Sessions

What's New

/resume-local — Resume terminal CC sessions from Discord

Mobile use case: quit CC in terminal → pick up from Discord on your phone → /handback when you're back.

• Auto-discover sessions from ~/.claude/sessions/ PID files + history.jsonl
• Select menu shows last prompt + project path for easy identification
• Blocks resume of still-running sessions (must /quit in terminal first)
• Dedicated lighter system prompt for resumed sessions
• isLocalResume DB flag to distinguish bot-created vs resumed threads

/handback — Return session to terminal

Resets the Discord thread and prompts claude --continue to pick up in terminal.

Bug fix: stderr capture

Claude CLI errors now show in Discord instead of bare (no output).

Full Changelog: v0.5.0...v0.6.0

v0.5.0

Features

• Replace thread-map.json with SQLite (better-sqlite3 + WAL mode) for crash-safe session storage
• Auto-migrate existing JSON data to SQLite on first startup (rename .bak after success)
• Per-entry upsert via saveEntry() instead of full-file overwrite
• Graceful shutdown on both SIGINT and SIGTERM (closes DB properly)

v0.4.2

Fixes

• Rewrite splitMessage with segment-based approach — code blocks are never broken across Discord message chunks
• Oversized code blocks (>2000 chars) are split and re-wrapped with proper fences on each chunk
• Long AskUserQuestion replies now use sendChunked instead of truncating at 2000 chars

v0.4.1

Fixes

• Fix duplicate message in thread history — current trigger message was included in the history block and appended again as prompt content

v0.4.0

Features

• Interactive Discord buttons for AskUserQuestion permission prompts (replaces plain text)
• Button click resumes Claude session with user's choice
• Chained AskUserQuestion support (button → resume → another question → buttons again)
• "Other..." button option for free-text answers

Improvements

• Extract sendAskButtons helper to deduplicate button rendering logic
• Extract createToolUseHandler helper to deduplicate streaming callbacks
• Add Discord customId length guard (.slice(0, 100))
• Simplify redundant try/catch in button handler reply flow

v0.3.0

Features

• Increase task timeout from 10 to 30 minutes for long-running operations
• Return partial results on timeout instead of empty error
• Show elapsed time in streaming preview (e.g. "working... (2m34s)")
• Display recent tool names in preview (e.g. "🔧 Read → Grep → Edit")

v0.2.0

Features

• Streaming response with real-time Discord message updates (stream-json mode, 1.5s throttle, 40-char minimum delta)
• Long message auto-splitting for streaming output

Fixes

• Correct ACP repository link in README
