# Slack Skill

Slack workspace integration with two components:

1. **Scripts** — 7 Python scripts for on-demand Slack operations (bundled here)

2. **Session Bridge** — connect THIS Claude Code session to Slack (background listener + inbox file, no extra API costs)

- > **Daemon & Soul Engine**: The Claudius daemon (unified launcher, soul engine, cognitive pipeline, three-tier memory, Soul Monitor TUI) now lives in its own repo: **[github.com/tdimino/claudius](https://github.com/tdimino/claudius)**. Install Claudius separately for daemon features.

+ > **Daemon & Soul Engine**: The Claudicle daemon (unified launcher, soul engine, cognitive pipeline, three-tier memory, Soul Monitor TUI) now lives in its own repo: **[github.com/tdimino/claudicle](https://github.com/tdimino/claudicle)**. Install Claudicle separately for daemon features.

## 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 Claudius via soul.md instructions (no XML machinery needed)

+ - Personality as Claudicle via soul.md instructions (no XML machinery needed)

## 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 listener.

## 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 via Claudius Session Bridge

- # (requires Claudius installed — see github.com/tdimino/claudius)

- cd ~/.claudius/daemon && python3 slack_listen.py --bg

+ # Connect this session to Slack via Claudicle Session Bridge

+ # (requires Claudicle installed — see github.com/tdimino/claudicle)

+ cd ~/.claudicle/daemon && python3 slack_listen.py --bg

python3 ~/.claude/skills/slack/scripts/slack_check.py

```

---

## Session Bridge

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.

- Requires Claudius daemon installed — see [github.com/tdimino/claudius](https://github.com/tdimino/claudius).

+ Requires Claudicle daemon installed — see [github.com/tdimino/claudicle](https://github.com/tdimino/claudicle).

```bash

# Connect

- cd ~/.claudius/daemon && python3 slack_listen.py --bg

+ cd ~/.claudicle/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

- cd ~/.claudius/daemon && python3 slack_listen.py --stop

+ cd ~/.claudicle/daemon && python3 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 Claudius with full cognitive steps — perception, monologue, dialogue, post, ack — in a single invocation. See `~/.claude/skills/slack-respond/SKILL.md`.

+ **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`.

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

## Script Selection Guide

| Task | Script | Example |

|------|--------|---------|

| Post a message | `slack_post.py` | `slack_post.py "#general" "Hello"` |

| Reply to a thread | `slack_post.py` | `slack_post.py "#ch" "reply" --thread TS` |

| Schedule a message | `slack_post.py` | `slack_post.py "#ch" "msg" --schedule ISO` |

| Read channel history | `slack_read.py` | `slack_read.py "#general" -n 20` |

| Read thread | `slack_read.py` | `slack_read.py "#ch" --thread TS` |

| Search messages | `slack_search.py` | `slack_search.py "query"` |

| Search files | `slack_search.py` | `slack_search.py "query" --files` |

| Add reaction | `slack_react.py` | `slack_react.py "#ch" TS emoji` |

| Upload file | `slack_upload.py` | `slack_upload.py "#ch" ./file.pdf` |

| Share code snippet | `slack_upload.py` | `slack_upload.py "#ch" --snippet CODE` |

| List channels | `slack_channels.py` | `slack_channels.py` |

| Join channel | `slack_channels.py` | `slack_channels.py --join "#ch"` |

| Find user by email | `slack_users.py` | `slack_users.py --email user@co.com` |

## 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.

---

## 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 |

| "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 |
