Sources, dates, and assumptions
After this, you'll be able to create a fact-check log and use it to move a deck from rough material toward a presentable file.

The idea
A deck needs a fact-check pass before it is used to make decisions or promises. This lesson asks you to make a fact-check log, not a prettier version of scattered notes. The output should be specific enough that someone could open the deck file and see what changed.

Here is the before and after: Before, numbers and claims are trusted because they made it into the deck. After, each claim has a source, date, owner, and status. For example, if you are preparing a sales presentation, the artifact should name the audience, slide job, proof, speaker note, or export check where that detail matters. A reviewer should be able to tell whether the deck is closer to being presented, sent, or handed off.
Now try it: Build a fact-check log from the deck and mark each item verified, needs source, outdated, or remove. Make one choice before asking Claude to write: which audience, which decision, which proof, which slide job, or which delivery mode matters most right now. That choice keeps the deck from becoming a generic presentation outline.
The lesson is done when the artifact moves the deck toward a real room, reader, or file handoff.

Watch out for
Paste this into Claude
Create a fact-check log for this deck. Extract claims, numbers, customer quotes, market statements, and promises. Return Claim, Slide, Source, Date, Owner, Status, Risk, and Fix. Deck: [paste]. If any input is missing, ask me up to three questions before producing the artifact. Then return five sections: Finished Artifact, Realistic Deck Example, Assumptions To Check, What I Should Use In The Next Lesson, and One Risk If I Present Or Send This Without Fixing It. Keep the answer practical enough that I can paste it into my deck working doc.
What a good response looks like
Finished Artifact: - a fact-check log - Why it matters: it gives the deck a concrete thing to inspect instead of a vague intention. - Use it next: paste this artifact into the next lesson before asking Claude to write, build, import, publish, or review anything. Reality Check: - The artifact names the user, input, decision, owner, or proof it depends on. - The weakest assumption is visible. - The next step can be completed in one sitting.

Paste this into Claude
Without rereading the lesson, explain why a fact-check log matters in three bullets. Then apply it to a second deck example: [describe a different audience, room, or topic]. Return What Changed, What Stayed The Same, What To Check Before Presenting Or Sending, and the exact next action.
What a good response looks like
Transfer Check: - What changed: the second example has a different audience, input, or delivery context. - What stayed the same: a fact-check log still needs a source, a review check, and a next step. - Before trusting it: inspect the delivery check that would catch a wrong assumption. - Next action: run the check once, then carry the revised artifact into the next lesson.

When this breaks
AI can help with this
Paste the exercise prompt into Claude with your real deck context. Ask Claude to interview you one question at a time, produce a fact-check log, challenge the weakest assumption, and rewrite the artifact once so it is ready for the next deck step.

You can now
You can explain a fact-check log in one sentence.
Key takeaways
Fact-checking protects the audience, the presenter, and the decision the deck is trying to earn.
