Opinionated conventions for focused, well-bound Cloudflare Workers at the edge.
Sizes database connection pools for Postgres/MySQL apps from a short JSON of services, pods, workers, threads and pool settings - worst-case connections at autoscale max and during deploy surges vs max_connections, busy connections from rps x hold time, per-process wait odds (Erlang C), CPU and memory limits, PgBouncer client and server limits. Recommends pool sizes or proxy settings. Includes an offline stdlib Python calculator with --self-test.
AST-based code pattern analysis using ast-grep for security, performance, and structural issues. Use when (1) reviewing code for security vulnerabilities, (2) analyzing React hook dependencies or performance patterns, (3) detecting structural anti-patterns across large codebases, (4) needing systematic pattern matching beyond manual inspection.
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.
Finds code nobody uses anymore: unused files, exports, routes, styles and dependencies, with proof for each one, and suggests small safe pull requests to remove them.
Plans a major framework upgrade step by step, such as React, Next.js, Django or Rails: reads the breaking changes, maps what in your code they hit, and splits the work into small safe pull requests.
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.
