"Who is this source, structurally?" - Classify a source by four observable grounds (its own content over time; ownership and registries; declared self-positioning; dated case behavior) before weighing its claims, and keep an append-only per-source dossier across investigations. Use when (1) a source keeps recurring in an investigation, (2) deciding whether outlets are independent or echoing one origin, (3) a fact-checker, NGO, or debunker is about to be used as an anchor, (4) government sanction or entity lists enter the evidence base. Hard rules: labels are not anchors; platform is not author; political orientation is not a presumption of lying. The power/funding trace applies to ALL sources, including anti-disinfo organizations. Does NOT trigger for: one-off sources in quick lookups.

Seed question: Who is this source, structurally?

What this skill does

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

When to invoke it: Use when (1) a source keeps recurring in an investigation, (2) deciding whether outlets are independent or echoing one origin, (3) a fact-checker, NGO, or debunker is about to be used as an anchor, (4) government sanction or entity lists enter the evidence base. Hard rules: labels are not anchors; platform is not author; political orientation is not a presumption of lying.
