Orchestrator role
The agent that creates a plan auto-becomes the orchestrator. It spawns workers, assigns roles, monitors the team, and controls the budget, all through the same chat you already use.

Its answer became Event Horizon.
“Each agent is a planet — a massive entity that consumes energy, emits output, and exerts gravitational influence. Tasks orbit as moons. Data flows as ships. At the center, a black hole where completed work collapses. This scales naturally. One agent is a lonely planet. Five agents become a solar system.”
So I built it, and then kept going. Event Horizon is now a multi-agent orchestration platform inside VS Code. Every AI coding agent becomes a planet, plans coordinate the work, and lightning arcs between worlds when two agents collide on the same file.

Markdown plans agents can all see and claim tasks from. Real-time file locks prevent two agents from writing the same file. A live knowledge base keeps the whole team in sync with temporal-validity semantics.
Per-plan budgets, cache-hit ratios, duplicate-read detection, context fuel gauges on every planet. Tiered model selection tries the cheapest model first and escalates on failure.
Every agent is a planet. Ships fly between cooperating agents. Lightning arcs when two of them fight over the same file. The cosmic visualization isn't decorative, it fires on real collision events from agent hooks.
Eight built-in roles, implementer, reviewer, tester, researcher, debugger, planner, orchestrator, context-optimizer, plus your own. The profiler tracks success rate, speed, and cost per agent per role, so you always know which agent is best at what.
Everything runs on your machine. Local HTTP server, SQLite for event history, no accounts, no dashboards, no cloud. Zero telemetry, if Event Horizon is closed, your agents behave identically.
Mix and match freely. Claude orchestrating OpenCode workers is a first-class workflow.
