Designing a Reusable Capability for Driver Comms

Problem shape

Dispatch-heavy businesses need drivers on the channels they already use. Building four separate inboxes is a trap: your team burns out tab-switching, and context never joins up.

Capability boundaries

• Ingress: Webhooks per channel normalize to a single message shape (text, media, location, voice).
• Platform: Tenant-scoped queries on every read; realtime fan-out per conversation; durable media storage.
• AI layer: Translation (both directions), document extraction, image cleanup, transcription.
• Operator UI: One timeline, channel switcher, bulk send with threaded replies.

Failure modes to design for

• Duplicate messages on webhook retries (idempotency keys).
• PII in logs (redact before observability pipelines).
• Model hallucinations on extracted weights — always keep the raw attachment.

Reuse signal

If you've built this twice, capability-ize it: one markdown runbook, one test harness, one set of environment variables. The third deployment should be configuration, not a rewrite.
