OMP unifies hooks, skills, MCP, and marketplace into a cohesive extensibility layer: hooks merge into extension runner's event bus, skills use description for semantic triggering, MCP adopts a 250ms fast-start gate with deferred fallback, marketplace supports dual scopes with Claude Code catalog compatibility.
Tool interface design boosts coding agent consistency by 4.7x while halving token usage; memory distillation lifts a 4B model's AppWorld accuracy by 27.2 percentage points to near-frontier level; institutional design experiments show that identical safety rules paired with different enforcement mechanisms yield violation rates ranging from 0% to 23%
Google outlined eight multi-agent design patterns: from the simplest Sequential Pipeline to the composable Composite Pattern. More complexity isn't always better — picking the right pattern matters more than stacking agents.
