Cross-Session Project State

About this workflow

Keep long-horizon work coherent across many sessions: externalized project state that any session can load, advance, and hand off.

What happens when you run it

1. 1
   The document a stranger could continue from is the standard.

   A session that does not advance the state never happened.

   Continuity is the claim - test it like one.

Best for

• •Recurring tasks you currently copy-paste between tools.
• •When a single prompt isn't enough — you need a chain where output(n) feeds prompt(n+1).
• •Fork and adapt if your inputs differ materially from the author's use case.
