POPL's full name is the routing test: Principles of Programming Languages. The venue's center of gravity is a general truth about languages — a semantics, a type discipline, a program logic, a proof technique — established by definition and theorem. Both theoretical and experimental papers are welcome under the posted scope, but an experimental POPL paper still orbits a principle. (Scope wording per the POPL series pages, read 2026-07-08.)
Popl Topic Selection 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/popl-topic-selection/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when deciding whether a project is POPL-shaped — a principle about programming languages carried by definitions and theorems — or better aimed at PLDI's implementation bar, OOPSLA's breadth, ICFP's paradigm focus, or LICS, CAV, CPP, ESOP, and journal outlets, judged by what the decisive evidence is.
The Popl Topic Selection 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).
mkdir -p ~/.claude/skills/popl-topic-selection curl -L https://claudskills.com/skills/popl-topic-selection/SKILL.md \ -o ~/.claude/skills/popl-topic-selection/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/popl-topic-selection/. Claude Code auto-discovers it on next session.
Skills live at ~/.claude/skills/popl-topic-selection/SKILL.md on macOS/Linux, or %USERPROFILE%\.claude\skills\popl-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/popl-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. Popl Topic Selection is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.
