mattstack marketplace

The Claude Code plugin catalog rt adds on every machine it sets up:

claude plugin marketplace add https://github.com/m4ttstack/mattstack-marketplace
claude plugin install mattstack@mattstack
claude plugin install fast-browser@mattstack

This repo is generated

Its whole tree is published from marketplace/ in m4ttstack/rt by scripts/release/marketplace.sh, one commit per release that changes it. Edits made here are overwritten by the next release; change the catalog in rt.

Plugin sources

Each plugin lives in its own repo and is pinned to a commit, so a given catalog commit always installs the same plugin code:

"source": { "source": "url", "url": "https://github.com/…", "ref": "main", "sha": "<commit>" }

Claude Code resolves sha. ref records which branch the pin came from, so marketplace.sh --refresh can re-resolve it; bumping a pin is a reviewed commit in rt, never an implicit follow-the-branch.

What mattstack brings

Beyond the skills, the pack ships a UserPromptSubmit + PostToolUse hook that stamps each turn with local time, zone, and UTC. It arrives with the plugin — there is nothing separate to install and no settings.json edit.
