Most "well-sourced" claims are one source wearing costumes: a stat born in a vendor's report, echoed by a blog, cited by a journalist, and now "widely reported" — three citations, one origin, zero verification. Triangulation is the discipline of asking two questions before repeating anything: where was this born (the provenance trace back through the citation chain to the original) and who has independently confirmed it (independence meaning different methods or data, not different websites). The output is a confidence grade and — the practical part — the phrasing that honestly matches it.
Source Triangulation 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/source-triangulation/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked is this claim actually true, verify this stat before the deck, everyone cites this number where's it from, or how solid is this source. Produces the provenance trace, the independence assessment, the confidence grade with its reasoning, and the repeat-it-as phrasing.
The Source Triangulation 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).
