MiniMax Open-Sources MCode Stack Turning Engineering Norms into Executable Agent Skills
MiniMax has open-sourced MCode Stack, a toolkit comprising 17 skills and 5 checklists designed to convert abstract engineering best practices into executable code review and audit workflows. The framework supports installation in MiniMax Code and Claude Code via a plugin marketplace, enabling agents to load specific SKILL.md files and traverse projects item-by-item for standardized checks. While offering practical engineering implementation solutions, no specific evaluation benchmark data has been published yet.

▲ MiniMax just open-sourced MCode Stack, the agent skills its team actually uses to build MiniMax Code.
The key idea is turning engineering essays into runnable checks. Each MCode Engineering Notes article ships as a SKILL.md skill or checklist. Your agent loads it with /skill-name and walks your project item by item.
The numbers: 17 skills across 2 stacks, plus 5 checklists. The independent-review skill gives a reviewer only 3 inputs: the diff, the requirement and test results. The long-command audit has 10 items, from re-runs to cleanup after compaction. It is a trade-off though: 0 eval results are published, even though one skill is all about measuring harness changes.
It is MIT licensed, with 6 skills under CC-BY 3.0 (adapted from Google Engineering Practices). It installs in MiniMax Code or Claude Code via a plugin marketplace......
