prime-agent vs grok-build
Long-running coding agents compared
prime-agent and grok-build are Rust-based agents for working with code through tools and long-running tasks. prime-agent emphasizes persistent context, background sessions, and recursive subagents, while grok-build focuses on an interactive terminal interface and headless workflows for scripts, CI, and editors.
prime-agent: Run Self-Improving Agents for Coding Work
Prime Agent is a coding and research agent built for long-running tasks, using a persistent Python environment, recursive subagents, and durable working context. It suits developers and researchers who need agents to keep working across sessions.
grok-build: Run an AI Coding Agent in Your Terminal
Grok Build is a Rust-based terminal coding agent that can inspect and edit a codebase, run shell commands, and handle longer tasks. It supports interactive use, scripting, and editor integration through ACP.

Key differences
- prime-agent is designed for coding and research, with retained context and workflows that can continue across sessions; grok-build centers on coding through a terminal agent.
- prime-agent uses a persistent Python environment to coordinate tools and recursive subagents; grok-build provides a full-screen terminal UI and an agent runtime with workspace tools and checkpoints.
- prime-agent supports detached sessions, scheduled work, heartbeats, and bounded autonomous runs; grok-build supports interactive and headless operation, including scripts and CI.
- prime-agent reports its license as NOASSERTION, while its README says MIT; grok-build uses Apache-2.0.
- grok-build supports editor integration through ACP and extension through MCP servers, skills, plugins, and hooks; prime-agent offers agent-to-agent messaging and reusable Python-package skills.
- grok-build has 27.2k stars and 5.1k forks, compared with prime-agent's 21.5k stars and 2.4k forks; both are unarchived.
Choose prime-agent if you…
- need work to continue across terminal disconnections or sessions.
- want recursive subagents, persistent goals, and reusable context refined over time.
- need recurring or parallel coding and research workflows in a persistent Python environment.
Choose grok-build if you…
- want a full-screen terminal interface for exploring and editing a codebase.
- need headless workflows for scripts or CI, or editor integration through ACP.
- prefer an Apache-2.0 licensed project with documented MCP, skills, plugin, and hook extensions.
