Greptile TREX runs PRs in sandboxes

Greptile launched TREX, an execution layer for its AI code review agent that writes and runs targeted PR tests in isolated sandboxes. The beta attaches logs, screenshots, traces, scripts, or videos so developers can verify failures instead of trusting static AI comments.

// ANALYSIS

This is the right direction for AI code review: less confident prose, more executable evidence.

–Static AI review hits a ceiling because many real bugs only appear at runtime
–Sandbox execution makes Greptile more useful as an independent validation layer for Cursor, Claude Code, Codex, Devin, and human-authored changes
–The claimed 20% bug-catch improvement matters, but teams will care most about false positives and setup friction
–Attaching artifacts to PR comments is a strong UX move because it turns AI findings into debuggable evidence
–The launch reflects the broader shift from code generation speed to verification throughput

Hashimoto flags 1500-line agent diffs for decomposition

Mitchell Hashimoto discusses his approach to working with coding agents on feature work, noting that if an agent generates a diff larger than 1500 lines, it signals the problem is too large and should be broken down. His pattern involves first attempting the entire feature with a loose "draw the owl" prompt before decomposing the task.
