Opinionated conventions for building fast, small and safe WebAssembly modules with Rust.
Compares an OpenAPI YAML/JSON spec to a list of implemented routes and flags drift: missing operations, extra routes, method mismatches, and path-parameter shape differences. Use when reviewing API PRs, before a release, or asking "does our code still match the OpenAPI?". Includes a stdlib Python checker with --self-test.
Audits foreground/background color pairs for WCAG 2.x contrast (AA and AAA for normal and large text), reports ratios and pass/fail, and notes color-blindness risks. Use when checking UI palettes, design tokens, or asking "is this gray-on-white readable?". Includes a stdlib Python contrast checker with --self-test.
Reviews HTTP caching headers (Cache-Control, Expires, ETag, Last-Modified, Vary, Set-Cookie) for pages, assets, APIs. Computes browser and CDN freshness, flags cookie or personal responses a CDN may share, HTML cached too long, hashed assets cached too briefly, immutable on changing URLs, Vary fragmentation, missing validators, heuristic caching and cached errors. Suggests a header per resource. Includes a stdlib Python checker with --self-test.
Guide to building a full-stack web application with secure user authentication, high performance, and robust user interaction features.
Finds out why your CI builds are slow: tracks job times over weeks, spots missing caches, serial steps and oversized runners, and suggests concrete changes ranked by minutes saved.
Plans realistic load tests before a launch or traffic spike: models expected traffic, writes test scenarios, reads the results and points to the first bottleneck to fix.
