# SkillOS Autonomous RSI Silicon Verification Market-Readiness Proof

**Status:** `PASSED_AUTONOMOUS_RSI_SILICON_VERIFICATION_MARKET_PROOF`

## Workflow

Semiconductor RTL verification, bug triage, assertion selection, and fix-plan recommendation.

## Why this matters

This is not an email example, invoice example, CloudOps example, or cyber defense example. It is an objective, high-value engineering workflow where agents must identify RTL bug classes, select appropriate assertions, propose fix plans, prevent design escapes, and reduce debug cost.

## Recursive Self-Improvement

SkillOS runs recursive self-improvement:

training failures → lessons → candidate assertion/fix rules → validation → released skill versions → holdout proof

## Holdout results

| Metric | Baseline | Final SkillOS RSI |
|---|---:|---:|
| Fully correct decisions | 14.2% | 100.0% |
| Bug-class accuracy | 14.2% | 100.0% |
| Assertion accuracy | 14.2% | 100.0% |
| Fix-plan accuracy | 14.2% | 100.0% |
| SEV1 recall | 11.1% | 100.0% |
| Design escape rate | 44.4% | 0.0% |
| Avg debug days | 19.797 | 0.425 |
| Avg cost | $3968946.96 | $55735.19 |
