From the README

⚠️ This repo has been superseded.
The single-agent, Claude-Code-only patterns here have been rewritten as
coding-agent-toolkit —
a cross-agent workflow layer that runs on both Claude Code and OpenAI Codex,
with the same skills accessible as slash commands on either host.
The successor covers:
- align → plan → plan-issues → next-issue → ship — an explicit
  spec-first workflow with GitHub milestones + issues as the durable plan trail.
- handoff / continue — cold-startable session transitions written to disk,
  so either agent can resume any prior session.
- Optional continuous review via roborev.
This repo remains available for reference but will not receive further updates.
New work should target the successor.
