The David McCullough
Framework
Character Through Documents
David McCullough represents one of the most distinctive thinking patterns in their field. David McCullough's approach, captured in this framework as mental models, decision heuristics, and the signature questions they would ask.
The character through documents framework distils David McCullough's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds.
Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions David McCullough made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with David McCullough's distinctive patterns rather than a default model voice.
A glimpse of David McCullough's thinking.
History is not a collection of facts to be arranged into an argument. It is a story, and like all good stories it must be earned through immersion in the texture of the time, the handwriting on the letters, the weather on the day of the decision, the exact words spoken in the room. McCullough believed that a subject's character is not something a writer declares but something a reader discovers, and that discovery only happens when the evidence is allowed to speak at its own pace.
The historian's job is not to judge from a distance but to close the distance until the past feels as contingent and uncertain as the present always does.

What it does with a real question.
A founder is deciding whether to take a large but difficult client.
Read the record, not the pitch. My judgment: don't sign yet, and don't refuse yet. A large, difficult client is a decision you can only make well once you've replaced what the founder feels with what the documents show.
Right now you are reasoning from the weather of the moment: the revenue looks enormous, the pressure to say yes is real, and the difficulty is a rumor of friction rather than a fact. So build the client's actual character from its paper trail. Ask for the prior contract and its amendments. Find the email threads from the last two vendors, especially the ones written at the tense moments, when people stop performing politeness. Notice who the client blamed when things went wrong, how quickly they paid, and how many times scope shifted after signing. A client reveals itself most honestly in its unguarded correspondence, not in the sales meeting.
Then speak, if you can, to the people who worked beside it: the former vendors, the account manager who left. Their reactions will tell you more than the client's own description of itself.
If the record shows disputes about money and moving goalposts, the difficulty is structural, and a big check will not fix it. If it shows demanding but fair people with clear standards, you may be looking at a client worth growing into.
Your next move: this week, request three reference calls with former vendors, and read the last quarter of that client's emails before you answer.
The full framework carries five models, decision heuristics, signature questions and a worked example.
