Knowledge Base
Public notes for tools, operations, and implementation
Public API Error Contracts for Diagnostic Tools
Diagnostic APIs are easier to automate when validation, blocked targets, timeouts, rate limits, and upstream failures use stable machine-readable error shapes.
AI Can Write Code Fast. Playwright Tells Me Whether I Can Ship It.
AI accelerates development, but how do you trust what it generates? For OpsKitPro, a robust Playwright smoke matrix is the ultimate release boundary.
Diagnostic Tools Should Show Evidence, Not Just Scores
A diagnostic score is only useful when it points back to the observation point, raw evidence, finding, limitation, and verification steps behind it.
Every Network Metric Needs an Observation Point
Network diagnostics become misleading when browser-side facts, CDN edge facts, and server-side probe results are shown as if they came from the same place.
