The governance layer for AI-generated code.
Copilot and Cursor write the code. Static analyzers grade the syntax. APMs watch what already broke. Tomosu sits above all of them — the layer that decides what reaches production, scores the risk, finds the change that caused the page, and writes the audit trail.

AI assistants generate, refactor, and merge code at machine speed. Review, change management, and audit trails still run at human speed. That gap is governance debt, and it compounds every sprint.
Tomosu closes it. Purpose-built AI agents — for policy, risk, context, and evidence — evaluate every change collaboratively in real time. No single model decides alone. Each agent owns a domain, challenges the others, and together they produce a governance verdict a monolithic tool can't.
Tomosu is not:
- an AI code assistant
- a static analyzer
- an APM or logging tool
- a PR review chatbot
- a CI pipeline runner
- a ticketing or ITSM platform
It's the layer above all of them.
Every application gets scored continuously across eight calibrated indexes that roll up into one trendable number — PRI:
| Index | What it measures |
|---|---|
| PRI | Production Reliability Index — the single master score |
| FI | Fragility Index — how likely this code is to break |
| DI | Drift Index — the gap between what dev expected and what production delivered |
| GC | Governance Compliance — adherence to your org's coding, security, and observability standards |
| RS | Runtime Signals — live error rate, latency, resource anomalies |
| CV | Code Volatility — churn and hotspot density |
| DV | Deployment Velocity — frequency and safety of releases |
| EEI | Escalation Index — the interrupt tax on engineering |
- Govern — Every PR clears a streaming evaluation lane: context resolved, policy aligned, risk composed, evidence written. Before merge, not after the page.
- Score — Eight indexes roll up into one PRI. Trendable across quarters, readable by engineering and the board without translation.
- Resolve — When something fails in production, the responsible change is on the table immediately. The same failure pattern doesn't ship twice.
- Prove — Every governance decision is logged with evidence, ready for SOC 2, ISO, or internal AI-use policy review.
Tomosu plugs in read-only across the tools you already run — Git, observability, ticketing. Live in days, measurable in weeks. No rip-and-replace.
The Free Edition is a plugin for VS Code, Cursor, and Antigravity. Scan a repository, get a real PRI in minutes, no procurement conversation required.
For teams that want the full closed-loop governance system, the guided pilot runs on a 90-day shape: baseline PRI in week two, IDE plugin and advisory merge gate on your first repos, then escalation routing and a closed feedback loop back into guardrails.
This repo is home for Tomosu's public Discussions — questions, feedback on scoring accuracy, integration requests, and anything you run into using the Free Edition. We read everything here; it shapes what we build next.
