FOCS has no supplementary-material upload, no appendix size cap, and no separate supplement deadline: the submission is one PDF, the CFP encourages it to be the full version, and everything beyond the abstract, references, and first ten pages is read at the committee's discretion (2026 CFP, checked 2026-07-08). "Supplementary material" at this venue therefore means the rest of your own paper — pages eleven onward — and the design question is how to serve two readers at once: the committee member who stops at page ten, and the assigned expert who reads to the end.
Focs 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/focs-supplementary/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when architecting everything after page ten of a FOCS (IEEE Symposium on Foundations of Computer Science) submission — a venue with no separate supplement channel where the paper itself continues past the guaranteed-read window — covering body organization, proof placement, and navigation for the discretionary reader.
The Focs 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 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
