Tool Methodology

Specification first

Every tool has a versioned definition covering purpose, audience, inputs, validation, processing, outputs, privacy, performance and failure behavior. The interface is designed only after that contract is clear.

Local-first processing

Private files and pasted content remain in the browser when Web APIs can complete the job. Public network diagnostics use server routes with protocol restrictions, repeated public-address validation, timeouts, response caps and throttling.

Result design

Outputs pair evidence with explanation. Scores are used only when a transparent formula exists. Warnings identify reviewable conditions rather than pretending to diagnose intent.

Quality checks

Releases check unique slugs, conditional assets, syntax, buttons, empty states, keyboard access, responsive layouts, privacy labels, schema and known dependency limits.
