FEP 2026 · FEP rewritten, technique by technique
The original FEP taught you to write the entire program inside the prompt. With the September 2026 models, half of that became a crutch. Seven lessons go technique by technique: what died, what’s only useful sometimes, what still holds, and what was missing. You’ll leave with your own prompts audited and rewritten.

The thesis
The prompt almost died. What really died was the part that held the hand of an AI that no longer exists. What remains is what was always yours: the destination, the guardrails, the criteria, and the responsibility.
The triage
Dead
Manual Chain-of-Thought, reasoning skeletons, persona templates, lists of “don’ts,” temperature, prefilling, manual chaining, humanization, the hundred prompts, the certification.
Only when useful
Few-shot, role as perspective, structured output, steps with approval, multimodal, ask first. Each with “use when” and “don’t use when.”
Continue
Clarity about the intended outcome, context, constraints as boundaries, criteria for good, brief iteration, the context window as a concept, security, responsibility.
New
Context with a home, skill as a manual, the four blocks, subtraction, gates and approval, effort instead of parameters, weekly sampling, a kit of twelve briefings.
What you’ll know how to do
Audit your prompts line by line with the line test (destination or crutch), and cut the nine techniques that became a burden without losing what was yours.
Write the six-part brief in place of the four ingredients, and take from it what repeats to create a context sheet and a skill of its own.
Decide case by case the six conditional techniques, each with its own "use when / don't use" table.
Migrate an old prompt to arrive at four blocks by subtraction, map the entry points for your first agent, choose a model and effort level, measure with a sample, and leave with three briefings from the kit.

Path
Leave with one of your prompts marked up line by line: destination or crutch.
Leave knowing why each one died and what to use instead.
Leave with a tested six-line briefing for a real task.
Leave with a context sheet and skill saved outside the prompt.
Leave with your personal “use when / don’t use” table.
Leave with a prompt migrated to four blocks and the gateway map.
Leave with the model and effort level set, Friday’s sample, and three briefings from the kit.
