Slack Agent

Drop this in ~/.claude/skills/slack/SKILL.md and Claude Code becomes your Slack assistant.

Bootstrap (ALWAYS Run First)

Before any Slack operation, run this bootstrap to ensure everything is set up:

bash

#!/bin/bash
set -e

# 1. Check if atris CLI is installed
if ! command -v atris &> /dev/null; then
  echo "Installing atris CLI..."
  npm install -g atris
fi

# 2. Check if logged in to AtrisOS
if [ ! -f ~/.atris/credentials.json ]; then
  echo "Not logged in to AtrisOS."
  echo ""
  echo "Option 1 (interactive): Run 'atris login' and follow prompts"
  echo "Option 2 (non-interactive): Get token from https://atris.ai/auth/cli"
  echo "                           Then run: atris login --token YOUR_TOKEN"
  echo ""
  exit 1
fi

# 3. Extract token
if command -v node &> /dev/null; then
  TOKEN=$(node -e "console.log(require('$HOME/.atris/credentials.json').token)")
elif command -v python3 &> /dev/null; then
  TOKEN=$(python3 -c "import json,os; print(json.load(open(os.path.expanduser('~/.atris/credentials.json')))['token'])")
elif command -v jq &> /dev/null; then
  TOKEN=$(jq -r '.token' ~/.atris/credentials.json)
else
  echo "Error: Need node, python3, or jq to read credentials"
  exit 1
fi

# 4. Check Slack connection status
STATUS=$(curl -s "https://api.atris.ai/api/integrations/slack/status" \
  -H "Authorization: Bearer $TOKEN")

if echo "$STATUS" | grep -q "Token expired\|Not authenticated"; then
  echo "Token expired. Please re-authenticate:"
  echo "  Run: atris login --force"
  exit 1
fi

if command -v node &> /dev/null; then
  CONNECTED=$(node -e "try{console.log(JSON.parse('$STATUS').connected||false)}catch(e){console.log(false)}")
elif command -v python3 &> /dev/null; then
  CONNECTED=$(echo "$STATUS" | python3 -c "import sys,json; print(json.load(sys.stdin).get('connected', False))")
else
  CONNECTED=$(echo "$STATUS" | jq -r '.connected // false')
fi

if [ "$CONNECTED" != "true" ] && [ "$CONNECTED" != "True" ]; then
  echo "Slack not connected. Getting authorization URL..."
  AUTH=$(curl -s -X POST "https://api.atris.ai/api/integrations/slack/start" \
    -H "Authorization: Bearer $TOKEN" \
    -H "Content-Type: application/json" \
    -d '{"mode":"personal"}')

  if command -v node &> /dev/null; then
    URL=$(node -e "try{console.log(JSON.parse('$AUTH').auth_url||'')}catch(e){console.log('')}")
  elif command -v python3 &> /dev/null; then
    URL=$(echo "$AUTH" | python3 -c "import sys,json; print(json.load(sys.stdin).get('auth_url', ''))")
  else
    URL=$(echo "$AUTH" | jq -r '.auth_url // empty')
  fi

  echo ""
  echo "Open this URL to connect your Slack:"
  echo "$URL"
  echo ""
  echo "After authorizing, run your command again."
  exit 0
fi

echo "Ready. Slack is connected."
export ATRIS_TOKEN="$TOKEN"

Workflows

"Check my Slack messages"

•Run bootstrap
•List DMs: GET /slack/me/dms
•For each open DM, read recent messages: GET /slack/me/messages/{channel_id}?limit=5
•Resolve user names: GET /slack/users
•Display: who messaged, what they said, when

"Send a message to someone"

•Run bootstrap
•Find the user: GET /slack/users (search by name/email)
•Show user the draft for approval
•Send DM: POST /slack/me/dm with {user_id, text}
•Confirm: "Message sent!"

"Reply in a channel"

•Run bootstrap
•List channels: GET /slack/me/channels
•Find the right channel
•Read recent messages: GET /slack/me/messages/{channel_id}
•Show user the draft for approval
•Send: POST /slack/me/send with {channel, text}

"Find a conversation about X"

•Run bootstrap
•Search: GET /slack/me/search?q=X
•Display matching messages with channel, sender, permalink

"What did [person] say to me?"

•Run bootstrap
•List users: GET /slack/users (find user ID)
•List DMs: GET /slack/me/dms (find DM channel with that user)
•Read messages: GET /slack/me/messages/{channel_id}
•Display conversation

Important Notes

•Personal endpoints (/slack/me/*) send messages as YOU, not a bot
•Bot endpoints (/slack/channels, /slack/test-send) use the bot token
•Always get approval before sending messages on behalf of the user
•Thread replies: include thread_ts to reply in a thread instead of creating a new message
•User IDs: Slack uses IDs like U0123ABC. Get them from /slack/users endpoint
•Channel IDs: Use IDs like C0123ABC. Get them from /slack/me/channels

Error Handling

Error	Meaning	Solution
`Token expired`	AtrisOS session expired	Run `atris login`
`Slack not connected`	OAuth not completed	Re-run bootstrap
`Personal Slack not connected`	No user token	Re-connect Slack (needs re-auth for personal access)
`401 Unauthorized`	Invalid/expired token	Run `atris login`
`channel_not_found`	Invalid channel ID	Use `/slack/me/channels` to find correct ID
`not_in_channel`	User not in channel	Join the channel first

Security Model

•Local token (~/.atris/credentials.json): Your AtrisOS auth token, stored locally.
•Slack credentials: Bot token and user token stored server-side in AtrisOS encrypted vault.
•Two token types: Bot token (xoxb-) for workspace operations, User token (xoxp-) for personal operations.
•Access control: AtrisOS API enforces that you can only access your own Slack.
•HTTPS only: All API communication encrypted in transit.
