Judges every subagent result
When an orchestrator fans work out to subagents, QSI reviews each result independently — so a confident-but-wrong edit does not slip through just because it looked plausible.
Completion checks for coding agents
Your coding agent says “done.” QSI checks before it merges.
In Cursor-like setups an orchestrator fans work out to subagents that write code, run tests, and edit files. QSI is the independent checkpoint at each handoff — it verifies a subagent actually finished in-contract before its result merges or feeds the next step. Frontier models now spawn hundreds of subagents that “verify outputs before reporting back” (Anthropic, Opus 4.8) — but a model grading its own work is not effective challenge. QSI is the external version of that check.

What it does
Three checks, one pre-merge checkpoint.
The agent does the building. QSI does the judging — and tells you which of its outputs you can ship and which one needs your eyes.
Flags uncertainty for a human
The results QSI is unsure about are surfaced with a calibrated confidence and a reason. Your reviewers spend their attention exactly where it matters, not on everything.
Verifies task completion
Beyond "is this correct," QSI checks "did the subagent actually do what it was asked" — did it complete the plan, touch the right files, call the required functions.
The agentic-coding problem
More autonomy means more confident wrong answers.
As agents take on more of the work, the bottleneck moves from writing code to trusting it. A subagent will report success on an edit that quietly breaks an edge case. QSI catches that — and it does it fail-open, so an agent that is doing fine is never stalled.
Surfaces what needs a human
Instead of reviewing every diff, your engineers review the handful QSI flags. The rest pass with a verdict attached, so you keep the speed of agents without inheriting their blind spots.
Check your coding agents before they merge — keep the speed, lose the blind spots.
