Fixing the 1.7x Higher Issue Density of AI-Authored Code — Vulnerability Audit, Self-Healing Test Suite, and 50% Churn Reduction in One Week
Reading time: ~12 minutes
|
TLDR ; AgamiSoft's 7-Day AI Code Cleanup PoC identifies and remediates the 1.7x higher issue density found in AI-authored code repositories. For a fixed fee, we deliver a full vulnerability audit, automated Self-Healing test suite, and logic error remediation — reducing Vibe Coding churn by 50% and protecting production stability. 16 out of 18 CTOs surveyed by AgamiSoft in Q4 2025 reported at least one production disaster directly attributable to unreviewed AI-generated code. The 7-Day PoC is the safety harness for enterprises that rushed into AI adoption without governance. |
In Q4 2025, AgamiSoft conducted structured interviews with 18 CTOs at US-based enterprises ranging from Series B startups to mid-market SaaS companies. The question was simple: has your organisation experienced a production incident in the past 12 months where the root cause was AI-generated code that was accepted into the codebase without adequate review?
16 out of 18 said yes. The incidents ranged from data exposure through an AI-generated SQL query with a missing WHERE clause, to a payment processing logic error in AI-authored checkout code that overcharged customers by a factor of 100 for a 6-hour window, to a security vulnerability in an AI-generated authentication module that exposed session tokens. In every case, the AI-generated code had passed a cursory code review by an engineer who trusted the tool's output without testing the logic.

CTO SURVEY FINDING 16 out of 18 CTOs (89%) reported a production disaster attributable to Vibe Coding in 2025. The average financial impact of each incident was $240,000 — including direct revenue loss, customer remediation, engineering time, and reputational cost. The total across the 16 incidents: $3.84 million in damage from code that was largely written by AI tools and accepted without adequate review. |
AgamiSoft is the Safety Harness for enterprises that moved fast into AI-assisted development and are now discovering the governance gap. The 7-Day Code Cleanup PoC is a fixed-price, fixed-scope engagement that gives your engineering leadership concrete visibility into your AI code risk posture — and a concrete remediation plan — in one week.

POC GUARANTEE AgamiSoft guarantees the following outcomes from the 7-Day Code Cleanup PoC: (1) All P0 production-threatening issues identified and remediated within the PoC scope. (2) OWASP Top 10 assessment completed with findings documented. (3) Automated test suite covering a minimum of 20 previously untested high-risk modules. (4) AI code review gate operational in your CI/CD pipeline. (5) 50% reduction in code churn rate within 30 days of PoC completion, measured against your pre-PoC baseline. If we do not deliver all five outcomes, we refund 50% of the PoC fee. |

The 7-Day PoC is designed as a standalone deliverable — a complete risk assessment and initial remediation with immediate value. For organisations whose PoC reveals significant debt requiring a full remediation programme, AgamiSoft offers a structured 60-day follow-on engagement:
• Week 1–2: Complete remediation of all P1 and P2 issues identified in PoC
• Week 3–4: Comprehension Debt clearance — documentation, ADRs, and refactoring of the most opaque AI-generated modules
• Week 5–6: Test coverage expansion — automated test generation to reach 80%+ coverage across the codebase
• Week 7–8: Governance programme — AI code review policy, engineer training, and ongoing debt dashboard

Your Situation |
Why the PoC Is Right for You |
|
You adopted AI coding tools fast in 2024–2025 and have never audited the output |
The PoC gives you your first honest view of what is actually in your codebase — no surprises in production |
|
You have experienced a production incident from AI-generated code |
The PoC remediates the root cause and installs governance to prevent recurrence |
|
You are preparing for a SOC 2 Type II or ISO 27001 audit |
The OWASP audit and remediation gives you documented evidence of security controls for your auditor |
|
Your engineering team spends more than 30% of sprint capacity on bug fixes |
The PoC identifies whether AI-generated defects are the primary driver — and fixes the worst offenders |
|
You are about to raise a Series B or C round and need clean due diligence |
Technical due diligence now routinely includes code quality assessment — the PoC gives you a defensible report |
|
