What is San?
San is an open-source terminal agent runtime built as one native Go binary with zero runtime dependencies. It keeps harness overhead to about 2.3k tokens, starts in roughly 0.01s, and lets you plug in models, skills, subagents and MCP servers while replaying any run in its inspector.

Pros: what San does well
- Tiny context footprint leaves room for real work
- Single 12 MB binary, no Node or Python needed
- Fully open: prompts, tools and providers are yours to change
Cons: where it falls short
- Terminal-first workflow may not suit everyone
- Young project with a smaller ecosystem
