Tools for OpenAI Codex CLI
The Codex-aware slice of the directory: orchestration, observability, sandboxes, and bridges built specifically for the OpenAI Codex runtime.
Codex shows up in this directory mostly alongside Claude Code - most of the interesting tooling is dual-engine. The picks below are the ones where Codex support is first-class, not bolted on: token cost dashboards (codeburn), session monitors (abtop, lazyagent, agent-deck), parallel runners (parallel-code), and remote bridges (cc-telegram-bridge, paseo).
Garden Skills - production skill pack for Claude Code, Cursor, and Codex
Three carefully-scoped skills: web-design-engineer (with an anti-cliche blocklist that breaks the generic-AI-landing-page loop), gpt-image-2 (80+ templates, three runtime modes including advisor-only fallback), and kb-retriever (layered data_structure.md navigation for bounded local-KB retrieval). Tested across Claude Code, Claude.ai, Cursor, Codex, Gemini, OpenCode.
wanman - worktree-isolated multi-agent runtime for Claude Code and Codex
