From the author

Prepare and manage durable MEX team handoffs in git-native project memory. Use when the user asks to hand work to a person or team, prepare an end-of-session handoff, save what the next engineer needs, create a MEX Relay, take or close a Relay, or invokes /mex-relay or $mex-relay. Keywords: mex, project memory, relay, handoff, team memory, Claude Code, Codex. Treat Relay as a memory baton, not chat, notifications, task assignment, issue tracking, or a Jira replacement; do not activate for ordinary status messages that are not durable handoffs.

Install

Each tab says whether it installs commit ee71f12, the one we checked, or the latest version.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie, Amp and Antigravity, and Claude Code for Cline. Kiro needs the folder copied by hand.

  git -C "$tmp" fetch -q --depth 1 origin ee71f124d92b3b59b6078638922f8afdd24072fd &&

  mkdir .claude/skills/mex-relay &&
  cp -R "$tmp"/skills/mex-relay/. .claude/skills/mex-relay/ &&
  rm -rf "$tmp"

If Claude Code was already running and this created the skills folder, run /reload-skills.

Or install the mex plugin it ships in. Installs the latest version, not the one we checked. Installs everything in the plugin, including any hooks, MCP servers and scripts our check doesn't cover.

  claude plugin install mex@mex --scope project

Claude Code docs

Pinned to commit ee71f12, the one we checked.

Skills in the Claude apps belong to your account rather than to a project.

Make mex-relay.zip, with the skill folder at the top level:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/mex-memory/mex.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin ee71f124d92b3b59b6078638922f8afdd24072fd &&
  git -C "$tmp" sparse-checkout set -- skills/mex-relay &&
  git -C "$tmp" checkout -q ee71f124d92b3b59b6078638922f8afdd24072fd &&
  out="$(mktemp -d)" &&
  cp -R "$tmp"/skills/mex-relay "$out"/mex-relay &&
  (cd "$out" && zip -qr - mex-relay) > mex-relay.zip &&
  rm -rf "$tmp" "$out"

In Claude, open Customize > Skills, select +, then + Create skill > Upload a skill, and choose mex-relay.zip.

On Free, Pro and Max plans, turn on Code execution and file creation (Create and edit files in newer settings) under Settings > Capabilities.

In a running Copilot CLI session, run /skills reload.

Or install it with gh skill, which also installs the commit we checked. Needs GitHub CLI 2.90 or later.

Gemini CLI docs

Pinned to commit ee71f12, the one we checked.

Codex, Cursor, Copilot, VS Code, Gemini CLI, OpenCode, Goose, Amp and Zed all read .agents/skills; Claude Code and Kiro list only their own folders.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/mex-memory/mex.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin ee71f124d92b3b59b6078638922f8afdd24072fd &&
  git -C "$tmp" sparse-checkout set -- skills/mex-relay &&
  git -C "$tmp" checkout -q ee71f124d92b3b59b6078638922f8afdd24072fd &&
  mkdir -p .agents/skills &&
  mkdir .agents/skills/mex-relay &&
  cp -R "$tmp"/skills/mex-relay/. .agents/skills/mex-relay/ &&
  rm -rf "$tmp"

Or use the skills CLI from skills.sh. Installs the latest version, not the one we checked. The skills CLI reports installs to skills.sh unless you set DISABLE_TELEMETRY=1.

npx skills@1.7.4 add mex-memory/mex --skill mex-relay

Agent Skills docs

What it can touch

From the files and frontmatter at commit ee71f12. This is how much a skill can do, not whether it is risky.

What it can touch: Scripts or outside hosts

Runs shell commands
Its instructions or files give the agent commands to run on your computer.

Pattern check

Pattern check: nothing flagged · commit ee71f12 · 27 Oct 2026

We checked every text file in this skill, at commit ee71f12 on 27 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

How the check works Report an incorrect finding

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

Agent Skills specPasses
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Note
  There is no license field, so readers can't tell whether they may reuse the skill. O2
  Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.
Claude CodePasses
Claude apps & API uploadPasses
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Note
  The description is 549 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
  Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
OpenAI (Codex & API)Passes
VS Code & CopilotPasses
