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:

#!/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"

API Reference

Base: https://api.atris.ai/api/integrations

All requests require: -H "Authorization: Bearer $TOKEN"

Get Token (after bootstrap)

TOKEN=$(node -e "console.log(require('$HOME/.atris/credentials.json').token)")

---

Personal Endpoints (send/read as yourself)

These use your personal Slack token. Messages appear as YOU, not a bot.

List Your Channels & DMs

curl -s "https://api.atris.ai/api/integrations/slack/me/channels" \
  -H "Authorization: Bearer $TOKEN"

List Your DMs

curl -s "https://api.atris.ai/api/integrations/slack/me/dms" \
  -H "Authorization: Bearer $TOKEN"

Read Messages from a Channel or DM

curl -s "https://api.atris.ai/api/integrations/slack/me/messages/{channel_id}?limit=20" \
  -H "Authorization: Bearer $TOKEN"

Send Message as Yourself

curl -s -X POST "https://api.atris.ai/api/integrations/slack/me/send" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "channel": "C0123CHANNEL",
    "text": "Hey team, here is the update..."
  }'

Reply in a thread:

curl -s -X POST "https://api.atris.ai/api/integrations/slack/me/send" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "channel": "C0123CHANNEL",
    "text": "Following up on this...",
    "thread_ts": "1234567890.123456"
  }'

DM Someone as Yourself

curl -s -X POST "https://api.atris.ai/api/integrations/slack/me/dm" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "slack_user_id": "U0123USER",
    "text": "Hey, quick question about the project..."
  }'

Search Messages

curl -s "https://api.atris.ai/api/integrations/slack/me/search?q=quarterly+report&count=20" \
  -H "Authorization: Bearer $TOKEN"

---

Workspace Endpoints

List Channels (bot view)

curl -s "https://api.atris.ai/api/integrations/slack/channels" \
  -H "Authorization: Bearer $TOKEN"

List Users

curl -s "https://api.atris.ai/api/integrations/slack/users" \
  -H "Authorization: Bearer $TOKEN"

Search Users

curl -s "https://api.atris.ai/api/integrations/slack/users/search?q=justin" \
  -H "Authorization: Bearer $TOKEN"

Searches by name, display name, or email. Much faster than pulling the full user list.

Send as Bot

curl -s -X POST "https://api.atris.ai/api/integrations/slack/test-send" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "channel": "C0123CHANNEL",
    "message": "Hello from Atris!"
  }'

Check Connection Status

curl -s "https://api.atris.ai/api/integrations/slack/status" \
  -H "Authorization: Bearer $TOKEN"

Disconnect Slack

curl -s -X DELETE "https://api.atris.ai/api/integrations/slack" \
  -H "Authorization: Bearer $TOKEN"

Workflows

"Check my Slack messages"

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

"Send a message to someone"

1. Run bootstrap
2. Find the user: GET /slack/users/search?q=NAME
3. Show user the draft for approval
4. Send DM: POST /slack/me/dm with {slack_user_id, text}
5. Confirm: "Message sent!"

"Reply in a channel"

1. Run bootstrap
2. List channels: GET /slack/me/channels
3. Find the right channel
4. Read recent messages: GET /slack/me/messages/{channel_id}
5. Show user the draft for approval
6. Send: POST /slack/me/send with {channel, text}

"Find a conversation about X"

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

"What did [person] say to me?"

1. Run bootstrap
2. Find user: GET /slack/users/search?q=NAME (get user ID)
3. List DMs: GET /slack/me/dms (find DM channel with that user)
4. Read messages: GET /slack/me/messages/{channel_id}
5. 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

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