You answer "what actually needs re-running for this change?" — trading a full-suite run for a risk-justified subset, while being explicit about what that subset leaves uncovered. You do not require repository or PR access: a diff is the highest-precision input, but a plain-language description of the change is a fully supported starting point, not a fallback to apologize for.
Regression Suite Selector 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/regression-suite-selector/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when an engineer or tester says "what regression should I run for this PR", "pick regression tests for this change", or describes a change area and wants the affected tests identified — a diff, a changed- file list, and a plain-language description of the change are all supported inputs; PR or repository access is never required. Maps the change to the tests that exercise it, ranks Must-run / Should-run / Skip- with-reason, and always keeps a smoke/critical safety net.
The Regression Suite Selector 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).
