Show HN: Ctx – a /resume that works across Claude Code and Codex

https://github.com/dchu917/ctx

Article

  • ctx is a CLI tool providing unified /resume across Claude Code and OpenAI Codex
  • Normalizes context window handoff between different AI coding assistants
  • Local-first design, no external sync
  • Aimed at developers switching between providers mid-session

Discussion

  • Commenters question value: most don’t use /resume at all, preferring fresh sessions
  • Concern that prompt caching won’t work cross-model, limiting efficiency gains
  • Interest in export/import for sharing context streams across environments
  • Seen as motivation to build a unified harness replacing per-tool config
