Other shops will tell you the speed comes from a clever template. Honestly it comes from scoping the same shapes of project enough times to know which parts genuinely take time and which parts you stop arguing about. The patterns are written down at /case-studies so you can see them before any engineering starts.
The other half is that I read OpenClaw's source code. When OpenClaw does something surprising, I open the file and read what is actually happening, instead of guessing for a week. That is how I shipped the cost-runaway fix that's now part of OpenClaw itself, reviewed and merged by Peter Steinberger, the creator of OpenClaw, and it is the same posture every OpenClaw engagement runs on.
