This synthesis records claims and practices from the cited sources; reported outcomes and product capabilities have not been independently verified.
Agent infrastructure matures into production-ready, cost-optimized stacks where harness engineering—context management, tooling, orchestration—rivals model weight importance. Four techniques cut unit costs ~90%: cheaper/OSS models (~50%), adaptive budgeting (~10%), tool pruning/cache tuning (~10%). Graphed connects 750+ marketing/sales sources (Meta, Google, Shopify, HubSpot, GA4, CRMs) into a synced data warehouse, deploying scoped agents (Facebook Ads, Google Ads, SEO, Cold Email, LinkedIn DMs, TAM Mapping) that read/write directly. Graphed MCP exposes the unified warehouse to any AI assistant for schema exploration and dashboard generation. Reported outcomes: Facebook Ads Agent shifted $2.4k from cold prospecting to retargeting (ROAS 3.2x→4.1x); Google Ads Agent cut $1.8k/day from underperforming keywords; one customer claims agent replaced two analysts with ROAS +40%. Persistent cloud instances with real credentials outperform stateless patterns. Box's custom harness reportedly outperforms raw API access on accuracy and latency. Knowledge work critically requires independent type engines to detect silently accumulated broken links and inconsistent structures.
Type adds a proposed organizational memory boundary: separate individual, team and company context.
