Open-source terminal agent harness lets Grok spawn parallel sub-agents
pzarevich · reddit · 2026-07-22
An open-source terminal coding-agent harness, agenc-core, shows Grok running reasoning, editing, tool use, and sub-agent spawning.
- It is a full CLI/TUI harness rather than a chat wrapper, with a permission model and multi-agent orchestration.
- The project reports strong results from an agent swarm setup: divisible tasks are split across parallel sub-agents, each with its own context, tools, and token budget.
- The TUI includes a project explorer, agents rail, approval pickers for tool calls, rendered Markdown responses, and an /effort toggle to trade latency for depth.
- It also integrates with Ledger hardware so value-moving actions require physical approval on-device; keys stay inside the secure chip.
- The harness can use Grok Imagine to generate images and short clips during tasks.
