Ramp Built Its Own In-House Coding Agent — 75% of Merged PRs Now Come From It
Summary
Ramp's Inspect (built on open-source OpenCode, not a custom harness) runs on remote sandboxed dev environments with full access to the same internal tools/data a Ramp engineer has (Slack, Linear, LaunchDarkly, sanitized prod DB), closing verification loops (tests, telemetry, visual screenshots) most third-party harnesses can't out of the box. Sessions are collaborative and public by default with no opt-out, credited with driving org-wide AI adoption; 150+ engineers have contributed to Inspect's own codebase.
Why this signal
The clearest, most concrete case study this cycle for focus areas #3 and #4 combined — 'context + data + remote agents beats off-the-shelf harnesses,' plus a directly relevant collaborative-by-default session design Thomas Engineering could borrow.
