How to Use Linear as a Second Brain for Claude Code and Codex
Alex Finn demonstrates a workflow that pairs Claude Code (or Codex) with Linear — a free, cloud-synced project management tool — to eliminate the context drift that plagues long vibe-coding sessions. Describe your app once in Claude Code; it auto-generates Linear projects, issues, acceptance criteria, and priorities. From then on, any device running Claude Code can say "work on the next task" and pick up exactly where the previous session left off — no re-explaining required.

Key Takeaways
- Linear is free up to a high usage ceiling and integrates natively with Claude Code and Codex via "connect apps" — no API key needed, OAuth login only.
- Claude Code auto-creates Linear projects and issues (with acceptance criteria, priorities, due dates, and scope) from a plain-English app description — replaces hours of manual project setup.
- Cloud-synced issue board means phone, iPad, and laptop all start from the same state — tell Claude Code "work on the next task" and it reads Linear, knows what to build, and starts immediately.
- Works with both Claude Code and Codex simultaneously — both can pull tasks from the same Linear board, enabling multi-agent coordination on a single project.
- Add a CLAUDE.md (or agent.md for Codex) with rules for how to use Linear — keeps behavior consistent and prevents drift across sessions.
