# Measuring Code Quality in the Age of AI-Assisted Development

Use autter's analytics to track how AI-generated code impacts your team's quality metrics, review velocity, and production stability.

- Team Performance

Your team adopted AI coding assistants six months ago. PRs are shipping faster. Lines of code per developer are up. But is the code actually better — or are you just shipping more of it?

Most teams can't answer this question because their existing metrics don't distinguish between human-written and AI-generated code. autter gives you that visibility.

## The metrics gap

Traditional engineering metrics were designed for a world where every line of code had a human author. They measure throughput (PRs merged, lines changed), velocity (cycle time, lead time), and stability (change failure rate, MTTR). These metrics still matter — but they're incomplete in the AI era.

Consider: your team's PR throughput doubled after adopting Copilot. Great. But your change failure rate also increased by 40%. Is the trade-off worth it? Which PRs are causing the failures? Are they correlated with the percentage of AI-generated code in the diff?

Without instrumentation at the merge layer, you're flying blind.

## What autter tracks

autter captures metrics at the point where code quality and team behaviour intersect — the pull request review.

### PR composition analysis

For every pull request, autter tracks the ratio of AI-generated to human-written code:

```
// Example: autter analytics API
const prAnalysis = await autter.analytics.getPRComposition({
  repo: "acme/backend",
  pr: 1842,
});

// {
//   total_lines_changed: 347,
//   ai_authored_lines: 198,
//   human_authored_lines: 149,
//   ai_ratio: 0.57,
//   issues_found: 4,
//   issues_by_source: { ai: 3, human: 1 },
//   review_cycles: 1,
//   time_to_merge: "4.2h"
// }
```

### Team-level quality dashboard

autter aggregates PR-level data into team and organisation dashboards:

| Metric | What it tells you |
| --- | --- |
| AI-authored ratio | What percentage of merged code is AI-generated? |
| Issue density by source | Do AI-authored lines have more issues per KLOC than human-authored? |
| Review cycle correlation | Do high-AI PRs require more review cycles? |
| Revert rate by source | Are AI-authored changes reverted more often? |
| Time to first flag | How quickly does autter catch issues vs. human reviewers? |
| Convention compliance | Are AI tools following your team's established patterns? |

### Trend analysis

The most valuable metrics aren't snapshots — they're trends. autter tracks how your quality indicators change over time and correlates them with events:

- **New team member onboarding** — does AI-authored issue density spike when new developers join?
- **Tool changes** — did switching from Copilot to Cursor change your AI code quality?
- **Rule updates** — did adding a new autter rule reduce a specific class of issues?
- **Sprint pressure** — does quality degrade near deadlines? By how much?

## Actionable insights, not vanity metrics

Data without action is overhead. autter surfaces specific, actionable recommendations based on your metrics:

### Bottleneck detection

> “Reviews from the platform team are averaging 3.2 days. 67% of their review time is spent on convention enforcement that autter could automate. Consider enabling auto-merge for convention-only findings.”

### Quality regression alerts

> “Test coverage in `src/payments/` dropped 8% over the last two sprints. 12 PRs merged without new tests — 9 of them were >70% AI-authored. Suggested action: enable the `require-test-coverage` rule for this module.”

### AI tool effectiveness

> “PRs using Cursor have 1.4x fewer autter findings than PRs using Copilot for the same codebase. The difference is concentrated in naming conventions and import patterns.”

## Integration with existing tools

autter's analytics complement — not replace — your existing engineering intelligence stack:

| Tool | What it measures | What autter adds |
| --- | --- | --- |
| GitHub Insights | PR throughput, contributor activity | AI vs. human attribution, quality-per-line metrics |
| LinearB / Sleuth | DORA metrics, cycle time | AI-correlated change failure rate |
| SonarQube | Static analysis coverage, code smells | Contextual quality scoring, convention compliance |
| Datadog / Grafana | Production error rates | Correlation between merge-time findings and runtime failures |

### Export and API access

All autter metrics are available via API and can be exported to your BI tools:

```
# Export team metrics as CSV
npx autter metrics export \
  --team backend \
  --period 90d \
  --format csv \
  --output ./reports/q1-quality.csv

# Query via API
curl -H "Authorization: Bearer $AUTTER_TOKEN" \
  "https://api.autter.dev/v1/metrics/team/backend?period=30d"
```

## Getting started

The analytics dashboard is available to all autter users. Connect your repository and data starts flowing from your next pull request — no additional configuration needed.

```
# View a quick summary in your terminal
npx autter metrics --team backend --period 30d
```

You can't improve what you can't measure. And in the AI coding era, what you need to measure has changed.
