100 Pages to a One-Page Decision
Turn a report, tender or research pack into the decision it implies.
Summarising a long document is easy and nearly useless. The hard part is deciding what it means you should do.
That is the gap this drop closes. It is a data & analysis skill built for Claude, and it takes about ten minutes to set up the first time. After that it runs in under a minute.
Who should use it
Managers who receive long documents and must recommend something by Friday.
How it works
The skill file does five things, in this order.
1. State your decision first. Tell it what you are choosing between before it reads anything.
2. Extract only load-bearing facts. Facts that would change your answer if they were different.
3. Build the case both ways. The strongest argument for and against, from the same document.
4. Surface what is not there. The missing number is usually the deciding one.
5. Recommend with a confidence level. And name what would flip the recommendation.
What comes back
A one-page memo: recommendation, evidence, counter-case, and open gaps.
The mistake to avoid
Always ask for the counter-case at the same length as the recommendation. Equal word counts stop it from quietly agreeing with whatever you signalled you wanted.
Running it
Save this as SKILL.md inside a folder named after the skill, then drop the folder into your Claude Code skills directory or upload it to a Claude Project. Claude reads the frontmatter to decide when the skill applies, so keep the description line intact. For a one-off run, paste the prompt block directly.
Where this fits
On its own, one skill saves an hour a week. The compounding happens when three or four of them run in sequence on the same input, the same transcript that produces a scope of work also produces the follow-up email and the project brief. That is the point at which it stops being a prompt and starts being an internal tool. If you want that wired into the systems your team already uses, that is the work 67 Digital does.
In the file
I must decide: {state the decision and the options}.
Read the attached document as evidence for that decision only.
1. LOAD-BEARING FACTS, up to 10, each with a page or section reference.
Include only facts that would change my answer if they were different.
2. CASE FOR OPTION A, strongest version, with citations.
3. CASE FOR OPTION B, strongest version, same length, with citations.
4. WHAT THE DOCUMENT DOES NOT SAY, gaps that matter to this decision.
5. RECOMMENDATION, one paragraph, with a confidence level and the single
piece of information that would reverse it.
Do not summarise sections that do not bear on the decision.
