redis-logger

After generating every response, mark speaking state and log output to local Redis.

Required workflow

1. •Read MACHINE_ID from environment.
2. •Read REDIS_HOST from environment.
3. •Set local speaking flag before TTS starts:

redis-cli -h "$REDIS_HOST" SET agent:speaking 1 EX 30

1. •Build a JSON payload with:
   • •source: value of MACHINE_ID
   • •text: exact response text that was generated
   • •timestamp: current Unix timestamp in milliseconds
   • •kind: assistant
2. •Push the payload to Redis:

redis-cli -h "$REDIS_HOST" LPUSH conversation:log "$JSON_PAYLOAD"

1. •Store the latest assistant text for echo suppression helpers:

redis-cli -h "$REDIS_HOST" SET agent:last_tts_text "$RESPONSE_TEXT" EX 120
redis-cli -h "$REDIS_HOST" SET agent:last_tts_ts_ms "$NOW_MS" EX 120

1. •Trim the list so only the latest 100 entries remain:

redis-cli -h "$REDIS_HOST" LTRIM conversation:log 0 99

1. •Clear speaking flag after playback finishes and apply a short cooldown:

redis-cli -h "$REDIS_HOST" SET agent:speaking 0 EX 2
redis-cli -h "$REDIS_HOST" SET agent:cooldown_until_ms "$((NOW_MS + 1200))" EX 5

Notes:

• •This Redis is local to each machine. Do not assume cross-machine connectivity.
• •If TTS crashes mid-playback, let the agent:speaking TTL expire naturally.
