System Requirements

Minimum requirements

Requirement	Details
Operating system	macOS 15 (Sequoia) or later
Architecture	Apple Silicon (M1 or newer) — Intel Macs are no longer supported
RAM	8 GB recommended
Disk	~100 MB for the app, plus space for your project files
Internet	Required for agent runtimes and Pentagon’s cloud sync

Software dependencies

Dependency	Why it’s needed
Git	Required — every agent that touches a git repo gets its own clone and branch
A coding-agent CLI	Required — one of Claude Code or Codex. You can install both and pick per agent.

See Agent Runtimes for runtime details and installation commands.

Performance notes

Each active agent runs its own coding-agent CLI process. Running 5+ agents simultaneously is normal; performance depends on your machine and your provider’s rate limits.
Pentagon itself is lightweight — the heavy work happens in the CLI processes.
