Can I use Flow-Next Impl Review with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

⚠ The author changed this skill after we tested it. The verdict below describes the version we ran on Jul 13, 2026; it's queued for a re-test.

This is not a drop-in skill: the SKILL.md points to `$HOME/.codex/scripts/flowctl` or `.flow/bin/flowctl`, and that binary 404s at the plugin's own skill-directory path - it only exists after the full flow-next plugin install (marketplace add + /plugin install, which also wires 21 agents and hooks). A plain git-clone-and-copy of just this skill folder produces a skill that cannot run its own Phase 0.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 4/5
Triggers reliably 5/5

Docs & honesty 4/5

What Flow-Next Impl Review does

Coordinates a 'John Carmack-level' implementation review by dispatching the diff to a different model (RepoPrompt on macOS, or Codex/Copilot/Cursor CLI) via the bundled flowctl tool, with trivial-diff triage, iteration-capped fix loops, and optional deep/validator/interactive passes, rather than letting the calling agent review its own code. It is one internal skill (user-invocable: false) inside the much larger flow-next plugin and is meant to be dispatched by /flow-next:work, not installed or triggered standalone.
