Most integration tools do one-direction syncing — they push data from System A to System B and call it done. The agent maintains true bidirectional sync with conflict resolution logic: when the same field is updated in two systems, the agent applies a configurable resolution rule — last-write-wins, source-of-record authority by field, or manual review queue for high-stakes fields like deal amount or close date. Every sync event is logged with the before/after values, the source of the update, and the resolution rule applied. No more mystery data changes showing up in the CRM with no audit trail.

Sync failures are invisible until they cause a problem — a rep emails a contact that marketing has unsubscribed, a deal closes in Salesforce but the Outreach sequence keeps running, a Marketo lead score is calculated on a company size that was updated six months ago in the CRM. The agent runs scheduled drift detection scans that compare field values across connected systems for every shared record and surfaces discrepancies as a prioritized list of mismatches. Drift is categorized by risk — a mismatched unsubscribe flag is critical, a mismatched phone number is low priority. Each mismatch shows the current value per system and a one-click resolution path.

Integration field mappings break when schemas change — a Salesforce admin renames a custom field, HubSpot releases a new property, Marketo updates a form field label. Without maintenance, these changes silently break syncs and the data stops flowing. The agent monitors schema changes across all connected systems and alerts when a field mapping is broken or at risk. When a mapping breaks, the agent surfaces a suggested remap based on field name similarity, data type, and historical match patterns — so the fix is a one-click approval rather than a manual mapping exercise. Configuration drift is caught before data drift begins.

Not all data should flow everywhere. GDPR consent flags should not be overwritten by any automated sync. Unsubscribe statuses must propagate within minutes, not hours. PII fields in certain regions may not replicate to specific storage locations. The agent applies configurable sync rules at the field level — which fields sync, in which direction, with what latency requirement, and with what override protection. Compliance-critical fields have explicit protection rules that cannot be bypassed by standard sync events. Every access to these fields is logged for audit purposes, including the agent, timestamp, and the resolution applied.
