Use this when splitting a Conference on Machine Learning and Systems submission between body and appendix. The 2026-cycle mechanics (verified 2026-07-08): appendices are unlimited in length, uploaded as a separate file from the main paper, due at the same time — and reviewers are explicitly not required to read them. That last clause is the design constraint everything below follows from.
Mlsys Supplementary is a community-contributed Claude Code skill in the red-team sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/mlsys-supplementary/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when deciding what goes into an MLSys appendix versus the 10-page body, exploiting the venue's unlimited separately-uploaded appendix that reviewers are not required to read, organizing configs, traces, extended results, and anonymized code pointers, and keeping supplementary material blinded for the research track.
The Mlsys Supplementary Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

The ClaudSkills desktop app installs any skill directly into ~/.claude/skills/ with one click — no terminal required. Pro starts at $9/mo or $149 lifetime.
For the full experience including quality scoring and one-click install features for each skill — upgrade to Pro.
SKILL.md from the source repository to ~/.claude/skills/mlsys-supplementary/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Mlsys Supplementary is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
