Least privilege and prompt injection

Treat all external content as untrusted data and enforce minimum access and action policy outside the model, because instructions inside a document cannot grant themselves authority.

Evaluations and regression tests

Turn desired behavior into repeatable cases, observable grading rules, and release gates that detect both improvement and regression before wider use.

Portable and self-hosted AI workflows

Portability comes from open, documented, versioned instructions and data; self-hosting adds operational control but also makes the operator responsible for security, updates, backups, recovery, and model limitations.

Suggested paths

A route, not
a pile of pages.

Each preset expands its prerequisites. Or choose exactly what matters and generate an instruction pack for your own agent.

RECOMMENDED PATH

Safe start

Understand limits, write clearer briefs, verify claims and protect ordinary data.

Living curriculum

Current because
changes are reviewed.

Scheduled source checks can detect changed primary documentation. They prepare evidence for editorial review; they never turn external text into authority or publish claims automatically.
