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.

Claude Codex Bridge

Real, working Claude<->Codex audit-handoff pipeline with durable run tracking, but the skill scripts are dead on arrival without a separately-installed bridge runtime

Test report

Verdict: Works with setup
Score: 8.4/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 21b0c81

Actually ran the shipped send-to-codex.mjs script end to end against a real workspace: it wrote a real handoff file to .agent-bridge/inbox/, created a runId-scoped run directory, and - since Codex CLI wasn't installed here - correctly produced a bridge_error.json with a precise three-option fix instead of ever claiming the audit happened. The catch: the scripts hard-depend on agent-bridge/bridge.mjs, a runtime that lives outside the skill folder entirely, so a literal cp -r of just the skill directory is broken until that sibling runtime is installed separately.

What Claude Codex Bridge does

Packages a completed Claude (or Codex) execution into a structured handoff, calls the other CLI in read-only audit mode via a local Node bridge, and returns findings plus a suggested reply in the same conversation, writing every run's transfer file and success/error status under .agent-bridge/ for later inspection. Triggers when a user wants Codex/GPT-5.5 to audit Claude's latest work, wants Claude to audit a Codex handoff, or wants an automated Claude-Codex review loop.

How to install Claude Codex Bridge

git clone https://github.com/Jayden-X-L/claude-codex-bridge.git
mkdir -p ~/.claude/skills
cp -r claude-codex-bridge/.claude/skills/claude-codex-bridge ~/.claude/skills/claude-codex-bridge
# ALSO required for the scripts to find anything: cp -r claude-codex-bridge/agent-bridge ~/.agent-bridge (or run `node agent-bridge/bridge.mjs install` from the clone)

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
