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.
