TL;DR: Autonomous code changes shift review to machine speed, so decision-model gates matter most when they decide whether a deeper scan is needed before commit, according to Corridor. Commit-path enforcement has to match agent speed or risky changes can move on before manual review catches them.
Editorial analysis by NHI Mgmt Group, based on content published by Corridor: “Choosing What We Scan: How Decision Models Halved our Costs and Reduced False Alarms”.
Key questions
Q: Why do decision-model gates reduce false alarms in code scanning?
A: They skip obviously safe changes before the expensive scan runs, which removes many opportunities for routine commits to trigger unnecessary alerts.
Q: How do you know if a commit gate is actually working?
A: A working gate should lower scan cost and latency without causing a steep drop in recall or a surge in missed vulnerabilities.
Q: What breaks when AI agents can make code changes faster than humans can review them?
A: Manual review stops being a meaningful control if it cannot keep pace with change volume.
Practitioner guidance
- Instrument commit-path gating before full scanning Place a lightweight decision step ahead of deeper vulnerability analysis so clearly safe diffs do not consume expensive scan capacity.
- Tune thresholds against real commit distributions Validate the gate on representative agent and human commits, then adjust the threshold to balance missed risk against latency and review volume.
- Separate gating quality from scanner quality Test the gate and the downstream scanner independently so a weak scanner does not hide a strong gate, or vice versa, in your evaluation results.
Bottom line: Autonomous coding changes the control problem because code can be created and committed at machine speed, before human review has time to react.

Agent-speed governance is now the relevant control problem: once autonomous coding systems can create, stage, and push changes continuously, human review stops being the primary safeguard and becomes a backstop. That shifts the security question from whether humans can review every commit to whether automated gates can make defensible decisions before a commit is accepted. The operational conclusion is that security control points must move upstream into the agent workflow.
A few things that frame the scale:
- 28.65 million new hardcoded secrets were detected in public GitHub commits in 2025 alone, a 34% year-over-year increase and the largest single-year jump ever recorded, according to the State of Secrets Sprawl 2026.
- Claude Code-assisted commits leaked secrets at a rate of 3.2%, more than double the human-only baseline of 1.5%, with peaks reaching 31 secrets per 1,000 commits in August 2025, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: What should teams do when autonomous agents are allowed to write production code?
A: Treat the agent as a governed change actor and restrict its access to the minimum needed for the task. That means limiting repository scope, controlling commit paths, and placing automated checks before release so the agent cannot move risky code downstream unchecked.
