• shunt-kimi — Moonshot kimi-k2.7-code
• shunt-deepseek — deepseek-v4-pro / -flash

Checklist

• PR title follows Conventional Commits
• Tests added or updated, and the suite passes (bun run test) — n/a (marketplace config only)
• Lint/format pass (bun run lint)
• Documentation updated if behavior changed — n/a
• No breaking change, or a BREAKING CHANGE: note is included — no breaking change

Notes

• These are remote git-subdir sources, so the Codex/Cursor generated marketplaces (.agents/plugins/marketplace.json, .cursor-plugin/marketplace.json) are intentionally not updated — multi-format only includes local ./plugins/* sources.
• claude plugin validate .claude-plugin/marketplace.json passes with only pre-existing informational warnings.

Code Review

This pull request updates .claude-plugin/marketplace.json to register seven new subagent plugins routed through the shunt inference layer: shunt-codex, shunt-xai, shunt-kimi, shunt-deepseek, shunt-zai, shunt-minimax, and shunt-mimo. Each entry defines metadata, source repository paths, and homepages. There are no review comments, and I have no feedback to provide.
