source-triangulation
Verify a claim before repeating it — the independent-sources test (three citations of one press release is one source), the provenance trace to the original, and the confidence grading that separates established from echoed. 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.

Same command for any agent — swap --agent for codex, cursor, copilot.

# Source Triangulation Skill 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. ## What This Skill Produces - **The provenance trace** — the citation chain walked back to the origin: who created this claim, how, when - **The independence assessment** — which supporting sources are actually independent vs. echoes of the same origin - **The confidence grade** — established / single-sourced / contested / unverifiable — with reasoning - **The repeat-it-as phrasing** — how to state the claim at its earned confidence ("one vendor survey suggests…" vs. the bare assertion) ## Required Inputs Ask for these if not provided: - **The claim, precisely** —

How do I install it?
Run `npx skills add mohitagw15856/pm-claude-skills --skill source-triangulation --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mohitagw15856/pm-claude-skills, a repository with 1,255 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
