Sarathy : My Personal _claw style_ Assistant

Sarathy : My Personal Assistant

Who is Sarathy and Why ?

Sarathy is my own AI assistant implementation focused on local models. While Openclaw was a revolutionary idea, it’s heavily bloated and impossible for me to understand the data flow. It caters to all needs. Other similar OC variants also quickly becoming bloated even though they start small.

Inspired by nanoclaw and karpathy tweet on personalizing agents, I decided to fork an implementation in the language I’m comfortable with. I forked off nanobot and I made Sarathy.

I built this to run 100% local with only the features I need.

Sarathy means helper, guide, driver, mentor in both Sanskrit & Tamil.

What's Different in Sarathy?

While nanobot served as the initial inspiration, Sarathy has evolved significantly with many architectural changes and new features focused on local-first AI assistance.

Textual-based Interactive Onboarding

• sarathy onboard launches a TUI wizard for first-time setup
• Guided provider selection and configuration
• Automatic workspace and skill template creation

Dynamic Skills System with Hot-Reload

• Skills auto-discovered at runtime from ~/.sarathy/skills/ and workspace

• No restart needed when adding/modifying skills
• YAML-based skill definitions with multi-line help text support

Gateway Management

• Full lifecycle management: start, stop, restart, status, logs
• Background daemon with log rotation
• tail -f style log streaming with --follow flag

Agent Enhancements

• Token usage tracking: Real-time display of token count and generation speed

Contribution Guidelines

As you can probably guess, I'm NOT interested (at the moment) to accept either feature requests or contributions to Sarathy. It is just for my own purposes. I have opened it to the public for others to get motivated (just like nanoclaw did). But if you find some security flaws and wanna be a good samaritan to point out, by all means do it.

At some point in future, I might consider making sarathy as a general purpose tool ^[Although the chance is pretty slim since there are tons of such claws out there.].
