description	Slack workspace integration: 7 on-demand scripts (post, read, search, react, upload, channels, users) + Session Bridge (connect any Claude Code session to Slack via background listener + inbox.jsonl). Daemon, soul engine, and memory system live in Claudicle (github.com/tdimino/claudicle).

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 Claudicle daemon (unified launcher, soul engine, cognitive pipeline, three-tier memory, Soul Monitor TUI) now lives in its own repo: 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 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).

# Verify token is set
echo $SLACK_BOT_TOKEN

First-Time Setup

1. Go to 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):

   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

# 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 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 Claudicle daemon installed — see github.com/tdimino/claudicle.

# Connect
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 ~/.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.

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.

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

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

For daemon-specific troubleshooting (soul engine, memory, launcher), see Claudicle docs.
