Opinionated conventions for packaging and shipping Kubernetes applications with Helm.
Rightsizes Kubernetes CPU and memory requests and limits from real usage (p50, p95 and max per container). Recommends requests at p95 plus headroom, memory limits above the peak and no CPU limits, and estimates the cores, GiB and money freed. Flags OOM kills, memory above the request, CPU throttling, missing requests or memory limits, overprovisioning and short data windows. Includes a stdlib Python rightsizer with --self-test.
Reviews PostgreSQL and MySQL schema migrations (raw SQL or ORM-generated) for table locks, rewrites, data loss, and breaking changes, then proposes safe zero-downtime rewrites with a clear verdict.
Reviews and rewrites Git commit messages to Conventional Commits quality — clear type/scope, imperative subject, useful body explaining why — and trains the author with concrete before/after feedback.
Reviews Dockerfiles for security, image size, build cache, and runtime reliability: secrets baked into layers, running as root, unpinned base images, curl piped to a shell, ADD misuse, leftover apt and pip caches, cache-busting dependency installs, shell-form CMD, and missing multi-stage builds or health checks, then writes a corrected Dockerfile and .dockerignore. Use when a user shares a Dockerfile and asks "review my Dockerfile", "why is my image so big?", or "is this container secure?".
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.
Compares environment variables across local, staging and production, finds missing, unused or mismatched settings before they break a deploy, and keeps your example env file honest.
Runs focused validation: tests, smoke checks, and acceptance criteria against a builder's patch.
Writes and runs tests for a teammate's change, reports failures with minimal repro steps, and asks for fixes.
