Upload documents, paste links or explain something in your own words. Every item becomes a visible file.
Twenty practical lessons take you from clear prompts and verification to visible agent memory, tests, security and self-hosting. Then build a free instruction pack for your own agent.
The agent is the student. Docker is the classroom; portable files are what the student takes with it.
The useful unit is not a clever prompt. It is a durable agent file: inspectable, versioned, correctable and approved.
Upload documents, paste links or explain something in your own words. Every item becomes a visible file.
The agent inspects new files together and asks only where authority, scope, conflict or exceptions remain unclear.
Quick answers and explanations become cognitive memory. Approve the files, then download the complete Codex ZIP.
Every public example is fabricated and safe. Open the file tree, follow the corrections, inspect the produced work and try a sandbox challenge.
A fully fictional agent history with versioned source files, one important correction and review-only output.
A fictional support agent that learns policy, studies a good example and is corrected after promising too much.
A fictional project agent with an explicit YAML contract, examples, corrections, tests and visible draft files.
The complete self-hosting source is open for people and companies. The interface keeps Git and YAML understandable; underneath, the agent receives a clean, portable Codex file structure.
The domain tells you which boundary you are in. Public guides are searchable. Private classrooms are not indexed. The security lab accepts only built-in synthetic cases.
Practical guides, fabricated agent histories, methodology, limitations and visible product changes.
Learn how agent training works →One person teaches one agent through files, processing, clarification, approval and a portable ZIP.
Open the private classroom →See least-privilege decisions and privacy receipts using fixed fictional records—never customer uploads.
