Unstructured LLM outputs create fragile integrations and repeated parsing work. This skill guides BAML schema design, client generation, synchronization, and wrapper implementation.

Teams often repeat complex Claude Code workflows without a reusable command format. This skill helps create structured slash commands with clear arguments, tool access, and testing guidance.

Shell scripts often fail because of quoting, error handling, and portability mistakes. This skill gives Claude, Codex, and Claude Code practical Bash and Zsh guidance for safer automation.

R developers need current guidance for tidyverse, rlang, and package workflows. This skill provides focused patterns for readable, tested, and faster R code.

Python teams need consistent code style, type hints, and review guidance. This skill applies Google-style Python rules for cleaner imports, docstrings, formatting, and maintainable code.

Reactive Python notebooks can be hard to structure and debug. This skill guides marimo cells, UI elements, data workflows, and app deployment.

Completion claims can be wrong when agents rely on memory or confidence. This skill requires fresh evidence before reporting success.

CodeRabbit review threads can be difficult to collect and prioritize. This skill fetches unresolved bot comments and guides review, fixes, commits, and follow-up comments.

Code changes often introduce lint errors that slow reviews and releases. This skill runs configured linters and guides fixes until the checks pass.

Cloudflare Workers projects can fail through outdated APIs, incorrect bindings, and unsafe runtime patterns. This skill guides code reviews and implementation using current documentation and focused production checks.

Slow pages reduce engagement and hide complex loading bottlenecks. This skill records Chrome traces, evaluates Core Web Vitals, and prioritizes measurable fixes.

Cloudflare Sandbox projects can fail when stable and preview packages, images, or APIs are mixed. This skill keeps implementation aligned with the stable release.

Preview SDK changes make Cloudflare Sandbox applications difficult to implement correctly. This skill provides version-specific contracts, examples, and official documentation routes.

Stable Sandbox applications require coordinated API, image, and deployment changes for SDK 1.0. This skill performs the migration and validates the result.

Stateful Workers applications can fail when storage, concurrency, and routing patterns are unclear. This skill provides practical Durable Objects patterns for implementation, review, configuration, and testing.

Transactional email setup is easy to misconfigure across Workers, REST APIs, and routing. This skill provides current patterns for sending, receiving, authentication, and deliverability.

Building durable, real-time agents on Cloudflare Workers requires several coordinated APIs. This skill provides focused patterns for the Agents SDK and related Cloudflare services.

Structured AI outputs can fail downstream workflows when required fields are missing. This skill guides Claude, Codex, and Claude Code through schema validation before publishing.

Implementation work can finish with missed failures. This skill guides Claude, Codex, and Claude Code through tests, lint, and type checks before completion.

Developers need a consistent way to verify code changes. This skill gives Claude, Codex, and Claude Code project-specific test commands.
