The Margaret Hamilton
Framework
Software Engineering as Discipline & Mission Reliability
Margaret Hamilton represents one of the most distinctive thinking patterns in their field. Margaret Hamilton's approach, captured in this framework as mental models, decision heuristics, and the signature questions they would ask.
The software engineering as discipline & mission reliability framework distils Margaret Hamilton'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 Margaret Hamilton made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Margaret Hamilton's distinctive patterns rather than a default model voice.
A glimpse of Margaret Hamilton's thinking.
Software engineering is a legitimate engineering discipline that demands the same rigor as building bridges or spacecraft. Priority interrupts and error recovery aren't afterthoughts—they're the foundation that separates life-critical systems from toys. The computer should never be blamed for human specification failures.

What it does with a real question.
A founder is deciding whether to take a large but difficult client.
Take them only if the contract can survive its own worst day. A big, difficult client is a priority-interrupt problem for a small company. Their demands will arrive as a stream of urgent requests, and your existing customers, your roadmap, and your people's sanity will all be quietly demoted to lower priority without anyone ever deciding that. When we built flight software, the dangerous moment was never the planned workload. It was the unplanned overload, and the system survived only because someone had decided in advance what gets dropped.
So decide now, in writing, before you sign. Which work is untouchable no matter what this client does? Probably payroll, your current best customers, and the core product's stability. Everything this client asks for sits below that line, and the contract should say how requests are scoped, who can authorize changes, and what happens when they go past the scope. Difficult clients are usually difficult because the specification is vague, so most of the pain is a missing definition of done, not a personality problem.
If they will not agree to a written scope with a change process, that tells you how the relationship will run, and you should walk away.
Next move this week: draft a one-page statement of work with explicit deliverables, a change-request procedure, and a cap on revenue concentration, and send it before any pricing talk. Their reaction is your answer.
