FOCS asks for "new and original research on theory of computation" and explicitly welcomes papers that broaden the reach of the theory of computing or raise important problems that can benefit from theoretical investigation (FOCS 2026 CFP, checked 2026-07-08 via focs.computer.org/2026/call-for-papers-2/). The selection question is therefore two-dimensional: is this a theorems paper whose significance survives a committee drawn from every corner of TCS, and is the April-anchored IEEE cycle the right launch window for it?
Focs Topic Selection is a community-contributed Claude Code skill in the security-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/focs-topic-selection/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when deciding whether a theoretical-computer-science result belongs at FOCS (IEEE Symposium on Foundations of Computer Science) — testing foundations-level significance, weighing the April deadline against sibling theory venues like STOC, SODA, CCC, ITCS, or CRYPTO, and applying the CFP's broaden-the-reach clause.
The Focs Topic Selection 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).
mkdir -p ~/.claude/skills/focs-topic-selection curl -L https://claudskills.com/skills/focs-topic-selection/SKILL.md \ -o ~/.claude/skills/focs-topic-selection/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/focs-topic-selection/. Claude Code auto-discovers it on next session.
Skills live at ~/.claude/skills/focs-topic-selection/SKILL.md on macOS/Linux, or %USERPROFILE%\.claude\skills\focs-topic-selection\SKILL.md on Windows. See the full install guide for step-by-step instructions.

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/focs-topic-selection/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. Focs Topic Selection is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
