Incident Communications
Authentication
IMPORTANT: Credentials are injected automatically by a proxy layer. Do NOT check for SLACK_BOT_TOKEN in environment variables — it won't be visible to you. Just run the scripts directly; authentication is handled transparently.
Bot Token Permissions
You authenticate as a bot (not a user). This means:
| Can do | Cannot do |
|---|---|
List channels (conversations.list) |
Search messages (search.messages — requires user token) |
| Read channel history (if bot is a member) | Read channels the bot hasn't been added to |
| Read thread replies | Access DMs between other users |
| Post messages and thread replies | |
| Look up user profiles |
If search is requested: Do NOT attempt search_messages.py — it will fail with a missing_scope error. Instead, use the channel-scanning workflow below.
Available Scripts
All scripts are in .claude/skills/incident-comms/scripts/
list_channels.py — List Channels
python .claude/skills/incident-comms/scripts/list_channels.py [--types TYPE] [--limit N] [--filter NAME]
# Examples:
python .claude/skills/incident-comms/scripts/list_channels.py
python .claude/skills/incident-comms/scripts/list_channels.py --filter incident
python .claude/skills/incident-comms/scripts/list_channels.py --types public_channel --limit 500
get_channel_history.py — Read Channel Messages
python .claude/skills/incident-comms/scripts/get_channel_history.py --channel CHANNEL_ID [--limit N]
# Examples:
python .claude/skills/incident-comms/scripts/get_channel_history.py --channel C123ABC456
python .claude/skills/incident-comms/scripts/get_channel_history.py --channel C123ABC456 --limit 100
get_thread_replies.py — Read Thread Replies
python .claude/skills/incident-comms/scripts/get_thread_replies.py --channel CHANNEL_ID --thread THREAD_TS [--limit N]
# Examples:
python .claude/skills/incident-comms/scripts/get_thread_replies.py --channel C123ABC456 --thread 1705320123.456789
post_message.py — Post Status Updates
python .claude/skills/incident-comms/scripts/post_message.py --channel CHANNEL_ID --text MESSAGE [--thread THREAD_TS]
# Examples:
python .claude/skills/incident-comms/scripts/post_message.py --channel C123ABC456 --text "Investigation update: found root cause"
python .claude/skills/incident-comms/scripts/post_message.py --channel C123ABC456 --text "Rollback completed" --thread 1705320123.456789
Workflows
Finding Recent Activity (Bot-Compatible Search Alternative)
Since search.messages requires a user token, use this workflow instead:
# Step 1: Find relevant channels
python .claude/skills/incident-comms/scripts/list_channels.py --filter incident
# Step 2: Read recent history from channels the bot is in (★ in list)
python .claude/skills/incident-comms/scripts/get_channel_history.py --channel C_INCIDENTS --limit 50
# Step 3: Dive into interesting threads
python .claude/skills/incident-comms/scripts/get_thread_replies.py --channel C_INCIDENTS --thread 1705320123.456789
Scan multiple channels to build context. Focus on channels with names like #incidents, #alerts, #engineering, #support.
Gather Context for New Incident
# Find incident-related channels
python .claude/skills/incident-comms/scripts/list_channels.py --filter incident
# Check the incident channel for recent activity
python .claude/skills/incident-comms/scripts/get_channel_history.py --channel C_INCIDENTS --limit 50
# Read a specific thread
python .claude/skills/incident-comms/scripts/get_thread_replies.py --channel C_INCIDENTS --thread 1705320123.456789
Post Investigation Summary
python .claude/skills/incident-comms/scripts/post_message.py --channel C_INCIDENTS --thread 1705320123.456789 --text ":clipboard: *Investigation Summary*
*Timeline:*
• 14:00 - Alerts started firing
• 14:05 - Investigation began
• 14:15 - Root cause identified
• 14:20 - Fix deployed
*Root Cause:*
Connection pool exhaustion due to unclosed connections.
*Resolution:*
Rolled back to v2.3.4, deployed fix in v2.3.5."

Best Practices
Reading Channels
- List first: Use
list_channels.pyto find channel IDs — don't guess - Check membership: Only channels marked ★ can be read (bot must be a member)
- Scan multiple: Check
#incidents,#alerts,#engineering,#support, etc.
Posting Updates
- Use threads: Keep updates in the incident thread, not the main channel
- Be concise: Busy responders scan updates quickly
- Include next steps: Always say what's happening next
Anti-Patterns
- Do NOT use
search_messages.py— it requires a user token and will fail - Do NOT post before reading — check what's already been discussed
- Do NOT guess channel IDs — use
list_channels.pyto find them
