HyperProbe Lets Agents Set Read-Only Breakpoints in Production

HyperProbe (YC S26) drops read-only virtual breakpoints onto exact lines in running production code. When real traffic hits one, it captures variable values across the call stack, streams them to a coding agent and disappears — no redeploy, no restart, no pause. SDKs for Node, Python and Java, with an MCP server exposing the engine. Measured overhead is 7–10ms in Node, 4–9ms in Python, 1–2ms in Java, under 1% CPU, with in-process redaction before anything leaves. The sharpest comment on the launch thread asked for competing hypotheses rather than a single answer: an agent can now be confidently wrong about a root cause very fast.
