Sigmod Supplementary is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when deciding what accompanies a SIGMOD submission beyond the 12 pages, covering extended technical reports, anonymized code and data links that survive multi-round review, appendix placement relative to the unlimited reference pages, and what reviewers actually open during a PACMMOD round.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
