MCode Stack: the MiniMax Code team's daily skills

17 SKILL.md workflows the MiniMax Code team uses every day: when to hand work to a subagent, keeping pull requests small, an independent review pass, waiting on long commands, catching a tired long session, and checking what each turn costs in context.

A prompt to try

Use subagent-split-check on this task and tell me whether it should go to a subagent or stay in the main loop.

Written by us so you can reuse it. Replace each [bracket] with your details.

Step by step

  1. Open the GitHub repo and read the What's inside table.
  2. In Claude Code: /plugin marketplace add MiniMax-AI/mcode-stack, then /plugin install ronny@mcode-stack (Codex: codex plugin marketplace add MiniMax-AI/mcode-stack, then codex plugin add ronny@mcode-stack).
  3. Or copy only the skills you want from stacks/ronny/skills into ~/.agents/skills/.
  4. Call one by name (for example /independent-review or /long-command-check), or let the agent load it from its description.

Watch out for
