OPAL Build
A building partner for complex work that plans first and waits for your approval before changing anything.
Start in plan mode for bigger jobs. Nothing changes until you approve the plan. Comment on any step or rewrite it.
Save how you like work done and reuse it. Skills run when a task matches, or when you call them by name.
Unclear jobs get a quick multiple-choice question, so the details are right before work starts.
Big jobs are split between helpers that research, build and check at the same time.
Link the tools you already use. Connections read and draft only — they never send on their own.
