Show HN: Ctxbin – A deterministic CLI for reliable AI agent handoffs (github.com)
1 points by superlucky84 135 days ago
Hi HN,

I built ctxbin, a minimal CLI that lets AI agents reliably save and load shared context using branch-scoped keys inferred from git.

The problem I kept hitting was that handoffs between AI agents (or even between sessions) were fragile and non-repeatable. ctxbin solves this by storing structured context, agents, and skills in Upstash Redis with deterministic keys.

Key ideas: - Branch-scoped context ({repo}/{branch} inferred automatically) - Explicit save/load semantics (no hidden state) - Reusable agents and skills (string, directory bundles, or GitHub refs) - Designed for agent-to-agent handoff, not humans

It works well with tools like Claude Code, Codex CLI, or any AI agent workflow. Feedback very welcome.

Built this after repeatedly losing context between multiple AI agents working on the same repo and branch.

I wanted something boring, explicit, and repeatable — no hidden memory or session magic. Curious how others here handle AI agent handoffs or shared context today.
