cross-ref

What this skill does

Audit a named GitHub repository for duplicate pull requests and missing issue-to-PR links.

cross-ref is part of the Developer Tools category — developer tools that help your agent write, review, debug, and ship code. You can install it on its own or alongside other developer tools skills from the OpenClaw catalog.

How to install cross-ref

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.
3. Search for cross-ref and click Install.
4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add cross-ref with a single command:

openclaw skills add cross-ref

This pulls cross-ref from ClawHub and installs it into ~/.openclaw/skills/cross-ref/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use cross-ref

Once installed, cross-ref activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.

Manual install (advanced)

If you prefer manual installation:

1. Click the Download .zip button above to grab cross-ref-1.1.2.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/cross-ref/ (create the directory if it does not exist).
3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
