# Slack Skill

Full Slack workspace integration with three modes:
1. **Scripts** — 8 Python scripts for on-demand Slack operations
2. **Session Bridge** — connect THIS Claude Code session to Slack (background listener + inbox file, no extra API costs)
3. **Unified Launcher** — `claudicle.py` with Claude Agent SDK, soul engine, per-channel sessions (requires SDK API key)

## When to Use This Skill

### Scripts (on-demand)
- Posting messages to Slack channels or threads
- Reading channel history or thread replies
- Searching messages or files across the workspace
- Adding or managing reactions on messages
- Uploading files or code snippets
- Listing channels, getting channel info, or joining channels
- Looking up users by name, ID, or email

### Session Bridge (recommended)
- Connecting any running Claude Code session to Slack
- Responding to @mentions and DMs with full tool access (this session IS the brain)
- No extra API costs — messages processed in the current session context
- Auto-notification of new messages via UserPromptSubmit hook
- Personality as Claudicle via soul.md instructions (no XML machinery needed)

### Unified Launcher (persistent, requires SDK API key)
- Running Claudicle as an interactive terminal + Slack bot in one process
- Responding to @mentions and DMs in real time as "Claudicle, Artifex Maximus"
- Multi-turn conversations in threads (per-channel session continuity via Claude Agent SDK)
- Per-user personality modeling (learns communication style, interests, expertise)
- Cross-thread soul state (tracks current project, task, topic, emotional state)
- Three-tier memory: working memory (per-thread), user models (per-user), soul memory (global)
- All Slack activity visible in terminal alongside direct terminal interactions

## Prerequisites

All scripts require the `SLACK_BOT_TOKEN` environment variable (a Bot User OAuth Token starting with `xoxb-`). Scripts also require `requests` (`uv pip install --system requests`).

```bash
# Verify token is set
echo $SLACK_BOT_TOKEN
```

### First-Time Setup

1. Go to [api.slack.com/apps](https://api.slack.com/apps) → Create New App → From Scratch
2. Name it "Claude Code" → select your workspace
3. **OAuth & Permissions** → Bot Token Scopes → add all:
   - `app_mentions:read`
   - `channels:history`, `groups:history`, `im:history`, `mpim:history`
   - `channels:read`, `groups:read`, `im:read`, `im:write`
   - `chat:write`
   - `files:write`, `files:read`
   - `reactions:write`, `reactions:read`
   - `search:read`
   - `users:read`, `users:read.email`
   - `users:write` (optional — enables green presence dot)
4. **Settings → Socket Mode** → toggle **ON** → generate an App-Level Token:
   - Name: `socket-mode`
   - Scope: `connections:write`
   - Copy the `xapp-` token
5. **Event Subscriptions** → toggle **ON** (no Request URL needed with Socket Mode) → **Subscribe to Bot Events** → add:
   - `app_mention` — channel @mentions
   - `message.im` — direct messages (required for DMs to work)
   - `app_home_opened` — App Home tab rendering
6. **App Home** → Show Tabs → enable **"Allow users to send Slash commands and messages from the messages tab"**
7. **Install to Workspace** → approve permissions → copy Bot User OAuth Token
8. Set environment variables (add to shell profile):
   ```bash
   export SLACK_BOT_TOKEN=xoxb-...   # Bot User OAuth Token
   export SLACK_APP_TOKEN=xapp-...   # App-Level Token (Socket Mode)
   ```
9. Invite the bot to channels: `/invite @Claude Code`

**After any scope or event subscription change**: reinstall the app (Install App → Reinstall to Workspace) and restart the launcher.

## Quick Start

```bash
# Post a message
python3 ~/.claude/skills/slack/scripts/slack_post.py "#general" "Hello from Claude"

# Read recent messages
python3 ~/.claude/skills/slack/scripts/slack_read.py "#general" -n 10

# Search the workspace
python3 ~/.claude/skills/slack/scripts/slack_search.py "deployment status"

# Connect this session to Slack (recommended)
cd ~/.claude/skills/slack/daemon && python3 slack_listen.py --bg
python3 ~/.claude/skills/slack/scripts/slack_check.py

# Start the unified launcher (requires SDK API key)
cd ~/.claude/skills/slack/daemon && python3 claudicle.py
```

---

## Session Bridge (Recommended)

Connect any running Claude Code session to Slack. A background listener catches @mentions and DMs → `inbox.jsonl`. This session reads the inbox, processes with full tool access, posts responses back. No extra API costs.

```bash
# Connect
cd ~/.claude/skills/slack/daemon && python3 slack_listen.py --bg

# Check messages
python3 ~/.claude/skills/slack/scripts/slack_check.py

# Respond to thread, remove hourglass, mark handled
python3 ~/.claude/skills/slack/scripts/slack_post.py "C12345" "response" --thread "TS"
python3 ~/.claude/skills/slack/scripts/slack_react.py "C12345" "TS" "hourglass_flowing_sand" --remove
python3 ~/.claude/skills/slack/scripts/slack_check.py --ack 1

# Disconnect
python3 ~/.claude/skills/slack/daemon/slack_listen.py --stop
```

**Soul Formatter** (optional): `scripts/slack_format.py` adds Open Souls cognitive step formatting — perception framing, dialogue extraction, monologue logging.

```bash
python3 slack_format.py perception "Tom" "What's the status?"   # → Tom said, "..."
echo "$raw" | python3 slack_format.py extract                   # → external dialogue only
echo "$raw" | python3 slack_format.py extract --narrate --log   # → narrated + logged
python3 slack_format.py instructions                            # → cognitive step XML format
```

**Automated Respond**: `/slack-respond` processes all pending messages as Claudicle with full cognitive steps — perception, monologue, dialogue, post, ack — in a single invocation. See `~/.claude/skills/slack-respond/SKILL.md`.

**Soul Activation**: `/ensoul` activates the Claudicle identity in any Claude Code session with persistent soul.md injection through compaction/resume. `/slack-sync #channel` then binds the ensouled session to a Slack channel. Both are opt-in per session. The soul registry (`~/.claude/hooks/soul-registry.py`) tracks all active sessions and their channel bindings — ensouled or not.

For full installation, architecture, inbox format, auto-notification hook, and troubleshooting, see `references/session-bridge.md`.

**App Home**: The Home tab renders automatically when a user opens Claudicle's profile (via `app_home_opened` in the listener). Shows live status, toolkit, cognitive architecture, memory system. Refresh manually:

```bash
python3 ~/.claude/skills/slack/scripts/slack_app_home.py "USER_ID"
python3 ~/.claude/skills/slack/scripts/slack_app_home.py --all
python3 ~/.claude/skills/slack/scripts/slack_app_home.py --debug   # print blocks, no publish
```

## Rate Limit Awareness

| Tier | Rate | Key Methods |
|------|------|-------------|
| **Tier 1** | **1/min** | `conversations.history`, `conversations.replies` |
| Tier 2 | 20/min | `conversations.list`, `users.list`, `search.messages` |
| Tier 3 | 50/min | `reactions.*`, `conversations.info`, `chat.update` |
| Tier 4 | 100+/min | `files.getUploadURLExternal`, `files.completeUploadExternal` |
| Special | 1/sec/channel | `chat.postMessage` |

All scripts handle rate limits automatically via `_slack_utils.py` (local cooldown + retry with `Retry-After`). See `references/rate-limits.md` for full details.

---

## Claudicle Unified Launcher

Interactive terminal + Slack bot in one process via Claude Agent SDK. Per-channel session continuity, full soul engine with three-tier memory, all Slack activity visible in terminal.

```bash
# Install
cd ~/.claude/skills/slack/daemon
uv pip install --system slack-bolt claude-agent-sdk

# Launch (terminal + Slack)
python3 claudicle.py

# Verbose / terminal-only
python3 claudicle.py --verbose
python3 claudicle.py --no-slack
```

**Requires**: `claude` CLI in PATH, `SLACK_BOT_TOKEN`, `SLACK_APP_TOKEN`, plus `claude-agent-sdk`.

For full installation, architecture, SDK integration, per-channel sessions, configuration, data flows, and threading model, see `references/unified-launcher-architecture.md`.

---

## Legacy Daemon (bot.py)

The standalone `bot.py` daemon is preserved as a fallback. It uses `claude -p` subprocesses instead of the Agent SDK. Use when the unified launcher isn't needed or for launchd deployment.

```bash
cd ~/.claude/skills/slack/daemon && python3 bot.py --verbose
```

### Production (launchd)

```bash
cd ~/.claude/skills/slack/daemon
./launchd/install.sh install    # load LaunchAgent
./launchd/install.sh status     # check if running
./launchd/install.sh logs       # tail logs
./launchd/install.sh restart    # reload
./launchd/install.sh uninstall  # stop and remove
```

---

## Soul Monitor TUI

A standalone Textual terminal app that shows Claudicle's inner life in real-time — cognitive stream, soul state, user models, sessions, and raw logs. Run in a separate terminal while the launcher or daemon is active.

```bash
cd ~/.claude/skills/slack/daemon
uv run python monitor.py
```

See `references/daemon-architecture.md` for panels, color coding, key bindings, and data sources.

### Inspecting Memory

```bash
cd ~/.claude/skills/slack/daemon
sqlite3 memory.db "SELECT key, value FROM soul_memory"
sqlite3 memory.db "SELECT user_id, display_name, interaction_count FROM user_models"
sqlite3 memory.db "SELECT entry_type, verb, content FROM working_memory ORDER BY created_at DESC LIMIT 20"
sqlite3 sessions.db "SELECT channel, thread_ts, session_id FROM sessions"
```

---

## New User Onboarding

Bootstrap personalized configuration by having Claudicle interview new users to build user models and generate CLAUDE.md files. See `references/onboarding-guide.md` for the full workflow.

---

## Troubleshooting

| Problem | Fix |
|---------|-----|
| Bot not responding to @mentions | Enable Socket Mode; verify `SLACK_APP_TOKEN` (xapp-) is exported |
| "missing_scope" error | Add the missing scope in OAuth & Permissions → reinstall app |
| No search results | Invite bot to channels with `/invite @Claude Code`, or use user token (`xoxp-`) |
| Rate limited (429) | Scripts auto-retry; reduce batch sizes |
| Launcher/daemon exits immediately | Verify `which claude` returns a path |
| "Credit balance is too low" | Check Anthropic billing; error now surfaces in Slack response |
| Soul engine XML parsing fails | Check `daemon/logs/claudicle.log`; fallback raw text is returned |
| "Sending messages turned off" | App Home → enable "Allow users to send Slash commands and messages from the messages tab" |
| No green presence dot | Add `users:write` scope → reinstall app |
| App Home tab blank | Subscribe to `app_home_opened` event |
| Monitor TUI won't start | `cd daemon && uv pip install textual psutil` |
| SDK import error | `uv pip install --system claude-agent-sdk` |
