Use this when assembling FAccT supplementary material. Two rules govern the split. First, the familiar one: the paper must be judgeable from the reviewed pages alone — appendices and released artifacts support the paper, they do not hold the argument. Second, the FAccT-specific one: the endmatter statements (Generative AI Usage, Ethical Considerations, Adverse Impacts, Positionality) are a distinct zone with their own page allowance and their own anonymity rules — get that zone right or risk a policy problem independent of the paper's quality.
Facct Supplementary is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/facct-supplementary/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when deciding what belongs in an ACM FAccT paper body versus its endmatter statements, appendices, and supplementary material — the 14-page acmart budget, the extra endmatter page for ethics/adverse-impacts statements, the rule that decision-critical evidence stays in the reviewed pages, mutually-anonymous supplementary material, and how to split an interdisciplinary paper between body, endmatter, and artifact.
The Facct Supplementary Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
