# Source verification

A reusable skill the "Walk into every call already briefed" recipe pulls in. Add it once and every agent on the team can use it.

Confirm every factual claim in the brief traces to a real source before delivery, and drop what can't be sourced.

## Method
1. Scan the draft brief for every factual claim: news, funding figures, leadership changes, headcount, product launches.
2. For each claim, find the source: a news article, the company site, a press release, or a LinkedIn profile update.
3. Attach the source as an inline markdown link next to the claim.
4. If no source confirms a claim, delete the claim from the brief — never guess or soften it into a vague statement.
5. Re-read the brief once more to confirm no unlinked factual claim remains.

## Rules
- Internal CRM data (deal stage, past emails) needs no external citation — only claims about the outside world do.
- One source per claim is the minimum bar; prefer a primary source (company site, filing, press release) over a secondhand mention.
- A dropped claim is not replaced with a vaguer version of itself — it is simply removed.
- Never mark a claim verified without opening and reading the source page.

## Output
The same one-page brief, with every external factual claim followed by its source link, and a one-line note of any claim dropped for lack of a source.
