Add Reactions

This skill adds emoji reaction support to ClaudeClaw's WhatsApp channel: receive and store reactions, send reactions from the container agent via MCP tool, and query reaction history from SQLite.

Phase 1: Pre-flight

Check if already applied

Check if src/status-tracker.ts exists:

test -f src/status-tracker.ts && echo "Already applied" || echo "Not applied"

If already applied, skip to Phase 3 (Verify).

Phase 2: Apply Code Changes

Ensure WhatsApp fork remote

git remote -v

If whatsapp is missing, add it:

git remote add whatsapp https://github.com/qwibitai/claudeclaw-whatsapp.git

Merge the skill branch

git fetch whatsapp skill/reactions
git merge whatsapp/skill/reactions || {
  git checkout --theirs package-lock.json
  git add package-lock.json
  git merge --continue
}

This adds:

• scripts/migrate-reactions.ts (database migration for reactions table with composite PK and indexes)
• src/status-tracker.ts (forward-only emoji state machine for message lifecycle signaling, with persistence and retry)
• src/status-tracker.test.ts (unit tests for StatusTracker)
• agent/skills/reactions/SKILL.md (agent-facing documentation for the react_to_message MCP tool)
• Reaction support in src/orchestrator/db.ts, src/channels/whatsapp.ts, src/orchestrator/types.ts, src/orchestrator/ipc.ts, src/index.ts, src/group-queue.ts, and agent/runner/src/ipc-mcp-stdio.ts

Run database migration

npx tsx scripts/migrate-reactions.ts

Validate code changes

npm test
npm run build

All tests must pass and build must be clean before proceeding.

Phase 3: Verify

Build and restart

npm run build

Service name: Derived from the directory name: com.claudeclaw.<dirname> (macOS) / claudeclaw-<dirname> (Linux). For example, if cwd is my-assistant, the service is com.claudeclaw.my-assistant. Determine the correct service name before running service commands below.

Linux:

systemctl --user restart claudeclaw

macOS:

launchctl kickstart -k gui/$(id -u)/com.claudeclaw

Test receiving reactions

1. Send a message from your phone
2. React to it with an emoji on WhatsApp
3. Check the database:

sqlite3 store/messages.db "SELECT * FROM reactions ORDER BY timestamp DESC LIMIT 5;"

Test sending reactions

Ask the agent to react to a message via the react_to_message MCP tool. Check your phone — the reaction should appear on the message.

Troubleshooting

Reactions not appearing in database

• Check ClaudeClaw logs for Failed to process reaction errors
• Verify the chat is registered
• Confirm the service is running

Migration fails

• Ensure store/messages.db exists and is accessible
• If "table reactions already exists", the migration already ran — skip it

Agent can't send reactions

• Check IPC logs for Unauthorized IPC reaction attempt blocked — the agent can only react in its own group's chat
• Verify WhatsApp is connected: check logs for connection status
