mergetrain

mergetrain is a plugin for Claude Code from yongjip/mergetrain. Its manifest loads nothing; the 2 skills, 1 MCP server it bundles cost 105 tokens per session together, scanned A, original, MIT.

A coding-agent add-on for operating a local mergetrain queue, a controlled queue that combines work from separate worktrees before pushing it. It includes agent instructions and a deployment action that requires human confirmation.

In plain words
What is it for?
Use it to manage local merge queues, coordinate worktree changes, and deploy approved results.
Why use it?

Security

Grade A, and why

mergetrain scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it installs

The manifest is a name and a version. 2 skills, 1 MCP server travel with it, and installing the plugin installs all of them — 105 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
