Technical Diagnostics Toolkit Skill

When to Use

• Investigating crawl/index anomalies, traffic drops, or Core Web Vitals regressions.

• Running scheduled audits ahead of major launches or migrations.

• Validating fixes before/after engineering deployments.

Framework

• Signal Triangulation – combine Search Console, log files, crawler output, and analytics deltas.

• Replication Scripts – document steps to reproduce issues (user agents, locales, device types).

• Root Cause Hypotheses – map symptoms to likely causes (render blocking, redirects, robots, schema errors).

• Fix Design – outline remediation options, risk level, dependencies, and testing approach.

• Validation & Monitoring – specify metrics and alerts to confirm resolution.

Templates

• Diagnostics worksheet (symptom, evidence, hypothesis, owner, next action).

• Crawl + render checklist per environment.

• Validation log capturing metrics pre/post change.

Tips

• Keep historical baselines to quickly detect regressions.

• Pair with engineering release notes to correlate incidents.

• Automate recurring crawls and lighthouse runs to catch issues early.
