Orchestrate deep research across any topic with epistemic rigor. Use when the user needs to investigate a question, verify claims, research a topic in depth, fact-check information, understand a complex subject, or find the best approach to an open-ended problem. Routes investigative questions to claim decomposition and source triangulation, and generative questions ("what's the best X?", "how should we design X?") to the agentic-researcher for evolutionary candidate evaluation. Applies adversarial self-checking and confidence-tagged findings with explicit gaps.

From the source SKILL.md

Investigate any question with systematic rigor, source triangulation, and radical honesty about what is known, unknown, and unknowable. The core output is a research brief where every claim carries an auditable confidence tag and every gap is explicitly named.

What this skill does

Spelunker is a community-contributed Claude Code skill in the science-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/spelunker/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user needs to investigate a question, verify claims, research a topic in depth, fact-check information, understand a complex subject, or find the best approach to an open-ended problem. Routes investigative questions to claim decomposition and source triangulation, and generative questions ("what's the best X?", "how should we design X?") to the agentic-researcher for evolutionary candidate evaluation.

Who uses this skill

The Spelunker Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. 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).
