API Watchdog

Repro-in-a-Box

Autonomous QA agent that finds bugs on your site, captures reproducible evidence (HAR files + screenshots), validates reproducibility, and integrates with Claude Desktop via MCP. 7 built-in detectors: JavaScript errors, network failures, broken assets, WCAG 2.1 accessibility, Core Web Vitals, mixed content, and broken links. 170 tests, 85% coverage.

Ally A11y CLI

The only accessibility CLI with real-time auto-fix and impact scoring. Published on npm as ally-a11y with MIT license, GitHub Actions CI/CD, and codecov integration.

Story arc

How this shipped

Building the tools that build the toolsThree beats: what pressed against the work, how the stack answered, and what changed once it was live.

I · Constraint

The brief

External API changes break production apps without warning. Manual monitoring is tedious and catches issues after they cause outages.

II · Build

The craft

Built automated monitoring that detects schema changes, response format differences, and deprecation notices. Runs continuously with alerting.

III · Proof

What moved after launch

Catches breaking changes before they hit production. Zero manual monitoring required. Alerts within minutes of API changes.
