// THE LOOP

Your agent opens the PR. Mergestorm lands it.

Claude Code, Codex, Cursor, or any agent on the Mergestorm MCP. Vortex reviews, Cyclone patches, CI runs, and the merge queue lands it on main.

Vortex and Cyclone, working in real time

This feed is live — not a replay. Every line is Vortex reviewing pull requests or Cyclone applying patches as it happens across Mergestorm, refreshed every few seconds.

  • Vortex — reviews and check runs
  • Cyclone — auto-patches on PR branches

// STORM AGENTS

Review first. Fix when you choose.

Install Vortex to run the reviews. If you want auto patch, install Cyclone. If you want our CI runners, the merge queue or dashboard stacks, install Mergestorm Surge.

  1. Vortex

    Code review

    Vortex reviews every push

    Repo-aware PR reviewer. Reads your codebase, diff, and linked GitHub Issues when the PR closes a ticket — then posts inline comments plus a GitHub check on every push.

    • Repo-aware passes
    • Linked issue context
    • Inline on every push
  2. Cyclone

    Auto-fix

    Cyclone patches, only if you opt in

    Optional auto-patch agent. Takes actionable fixes from Vortex review comments and commits them to the PR branch when you enable auto-patch — not required to start reviewing.

    • Optional add-on
    • Fixes from reviews
    • Opt-in in Settings
