Contributor Setup — Local Tooling for Skill Contributors

Help a contributor get their local environment ready to submit changes to the public timescale/marketing-skills repo. This skill does not submit any changes — it only makes sure the tools exist. Once this passes, the contributor can use /skill-contributor or just ask Claude to help ship changes.

The three things this skill checks:

1. gh — GitHub's command-line tool, used to open PRs without leaving the terminal.
2. gh auth — an authenticated GitHub session on the machine.
3. git user identity — user.name and user.email, so commits show up with the contributor's name attached.

Keep the tone light. This is a one-time setup, not a rite of passage.

Step 0: Runtime check (bail if Cowork)

Detect the runtime by tool availability:

• If the google_drive_search tool is available → Cowork. This skill is Claude Code only. Tell the user:

  "This skill is Claude Code only — it probes and modifies your local machine, which I can't do from Cowork. If you're ready to submit changes from Cowork, just run /skill-contributor and it'll walk you through everything."
