Complete workflow for developing new features from design to deployment. Use when starting a new feature, adding functionality, or building something new.

Use when tests have race conditions, timing dependencies, or inconsistent pass/fail behavior - replaces arbitrary timeouts with condition polling to wait for actual state changes, eliminating flaky tests from timing guesses

Use when invalid data causes failures deep in execution, requiring validation at multiple system layers - validates at every layer data passes through to make bugs structurally impossible

Use this skill when building evaluation frameworks to measure LLM quality, safety, accuracy, or alignment including test suites, human eval rubrics, automated evals, and metrics design. Not for training or fine-tuning models. Not for dataset curation or benchmark comparison across publicly available models.

Structured plan-writing skill adapted from obra/superpowers. Produces actionable plans that map directly to cortex workflows and tasks.

Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always

Score concepts on impact/delight/effort and pick a 1-day spike.

Evaluate documentation information architecture: navigation paths, discoverability, progressive disclosure, cross-linking, and mental model alignment. This skill should be used when restructuring docs, adding new sections, or when users report difficulty finding information.

Fast, high-signal accessibility triage for pages, components, or PRs targeting WCAG 2.2 AA compliance.

Helm chart development patterns for packaging and deploying Kubernetes applications. Use when creating reusable Helm charts, managing multi-environment deployments, or building application catalogs for Kubernetes.

Use when running builds, executing tests, or improving developer experience workflows - provides structured guidance for build/test execution and DX improvement.

Use when adjusting reasoning depth, budgets, or metrics visibility - provides guidance for selecting and applying reasoning controls safely.
