Inspect runs coding tasks in prepared remote environments at Ramp. It can run tests, read telemetry and feature flags, and inspect the frontend. Ramp also builds other agents on its platform, including agents that monitor production and propose fixes.
An @inspect mention in Slack reads the thread context, works in its sandbox, and raises a pull request with the fix[Source 2, Source 5]
Where people stay involved
People review, approve, or guide the agent’s work here.
Reported: Sessions open pull requests with the user token, self-approval is blocked, and production merges keep human review; multiplayer sessions add live human collaboration.
Supervision level
Work-product review
A person reviews the draft or implementation.
3/5Level 3 of 5
Inspect coding task → reviewed production merge[Source 1]
All frontier models, MCPs, custom tools, skills[Source 1]
Harness
OpenCode (server-first) as the agent runtime; a plugin blocks writes until sync completes; expanded into production monitoring and self-maintenance; Inspect itself is built with React/Vite, Cloudflare Durable Objects, SQLite, and the Cloudflare Agents SDK[Source 1]
Sandbox
Modal sandboxes; per-repo images rebuilt every 30 min from snapshots; warm-on-keystroke; a pool of warm sandboxes[Source 1]Fully documented: Modal images rebuilt every 30 minutes, snapshots, warm-on-keystroke, and a warm pool.
Tool access
Wired into Sentry, Datadog, LaunchDarkly, Braintrust, GitHub, Slack, Buildkite; monitors production, triages issues, proposes fixes; debugging queries a sanitized read-only production DB replica and Snowflake[Source 1]
Knowledge
Skills that encode how Ramp ships; repo images with the full dev env (Vite, Postgres, Redis, RabbitMQ, Temporal, Chromium, VS Code Server)[Source 1]
Context management
Sandbox snapshots persist session state for follow-ups, and every client change syncs to the session[Source 1]
Credentials
GitHub auth per user; the sandbox pushes the branch, an API opens the PR with the user's token (no self-approval); production merges retain human review[Source 1]
Repository images and snapshots prepare dependencies and build state before sessions start[Source 1]
OpenCode runtime
OpenCode runs as a server with a typed SDK and plugin interfaces[Source 1]
Multiplayer sessions
Any number of people in one session; each change attributed to its author[Source 1]
Validation and failure handling
Verify its own changes
Inspect runs tests, reviews telemetry and feature flags for backend changes, and visually verifies frontend changes with screenshots and live previews[Source 1, Source 5]

Lessons
Reported opinion: Ramp argues that controlling an internal tool lets it tailor the system to its own codebase.[Source 1]
Reported opinion: Ramp credits visible use in shared channels with helping Inspect spread without a usage mandate.[Source 1]
Reported opinion: Ramp values remote agent sessions for concurrent work without tying up a developer's laptop.[Source 1]
Ramp builds repository images ahead of a request, then synchronizes recent code when a session starts.[Source 1]
Inspect adoption grew after Ramp changed it from a Chrome extension into a centrally configured remote development environment.[Source 5]
Reported: The captures document the @inspect Slack bugfix run end to end; larger builds are kicked off the same way but the thread fix is the one complete run.

75% of merged PRs raised by Inspect sessions (May 2026)
Duplicate representation of Headline claim. Same 75% merged-PR share, same May 2026 period, and the same merged-PR denominator; adds nothing the headline lacks.

The article describes simultaneous sessions and calls background operation better for this use. It does not supply a general local-versus-remote benchmark.
The image process includes cloning, dependencies, setup, and snapshots on a 30-minute cadence. A final synchronization remains, so setup is not literally eliminated.
