Built tasuki — an AI CLI Orchestrator that Seamlessly Hands Off Between Tools

#go #cli #ai #programming

I built and open-sourced tasuki, an AI CLI orchestrator that automatically rotates between Claude Code / Codex CLI / GitHub Copilot CLI based on priority.

Motivation

I’m the kind of person who prefers subscribing to multiple AI tools at $20–$30 each rather than committing to a single $100–$200 plan. I want to explore different tools and continuously feel the differences between models.

However, doing this means hitting usage limits fairly quickly, which interrupts workflow and requires manual switching — something I found annoying.

Each AI has its strengths — Codex for review, Claude for conversation, etc. But unless you’re extremely opinionated, there’s value in constantly rotating through tools and experiencing their evolution. If you stick to one, you may miss when another becomes better at something.

The switching decision itself is trivial labor — so I wanted to automate it.
That’s why I built tasuki.

Instead of treating rate limits as a constraint, I treat them as an opportunity to move to another model.

Intended Workflow

  1. Prioritize Claude Code and Codex CLI (5-hour windows)
    Since their reset cycles are short, it’s more cost-efficient to exhaust them first.

  2. Once both 5-hour windows are exhausted, switch to GitHub Copilot CLI
    Copilot operates on a monthly quota, so it works well as a “bridge.”

  3. When Claude / Codex reset, switch back automatically
    Monthly quota should be preserved as much as possible.

What It Does

  1. Native UI stays intact
    Each CLI runs inside a wrapped PTY, preserving the original interactive experience.

  2. Automatic switching based on usage
    Adapters monitor CLI output streams and trigger a handoff when a threshold (default: 95%) is reached.

  3. Context-aware handoff
    Progress is written to .tasuki/handoff.md and injected into the next provider.

Try It in 5 Minutes

Use everything. Keep exploring.
tasuki reduces the friction of doing that.
