The full bundle: hub (/sb-hub: onboarding check + orchestrator + navigator) + 10 standalone skills (sb-setup, sb-figma, sb-inventory, sb-health, sb-flows, sb-stories, sb-wrappers, sb-explore, sb-ship, sb-audit) over a shared agent pool.
All embedded, MCU debugging, firmware, and library-integration Agent Skills maintained in this repository.
8 playbook skills: spec-driven development, TDD, branch finishing, PR feedback, handoff, hooks and guardrails, game feature loop, and security research
Data science and data engineering agents for visualization (D3, Highcharts), notebooks (Jupyter, Google Colab), R, and Python data engineering.
Frontend development specialists for React, Vue, Next.js, CSS, HTML, and UI/UX design. Comprehensive coverage of modern frontend technologies.
Portable skills library: documentation lookup, GitHub operations, dependency intelligence, UI/UX patterns, and skill crafting
LLM and prompt evaluation with Promptfoo, DeepEval and Ragas, Giskard vulnerability scans, Langfuse tracing, and golden-dataset regression suites. Audits eval suites for methodology errors. Agents (prompt-eval-reviewer, llm-red-team-planner) review an eval suite and plan adversarial probe campaigns across the OWASP LLM Top 10.
ai-mlBackground job and queue testing for Sidekiq, Celery, BullMQ, SQS, RabbitMQ and Kafka consumers, plus cron schedules and idempotency guarantees. A read-only critic agent (async-job-health-critic) flags missing retry limits, absent dead-letter routing, and other at-least-once reliability defects in queue and worker code.
backend-distributedMobile app testing: XCUITest and Espresso for native apps, Appium, Detox and Maestro across platforms, Flutter tests, and mobile accessibility checks. XCUITest also covers macOS desktop apps, and a tiered device matrix keeps CI cost down. An authoring agent (mobile-test-author) detects the driver, scaffolds a harness when none exists, and writes one test per spec. Mobile-web viewport emulation lives in qa-web-e2e.
functional-testingLoad and performance testing with k6 and JMeter, Lighthouse CI for Web Vitals, SLO-driven load plans, and performance budget gates. Covers tool choice and load profiles (with Gatling and Locust references), per-interaction INP budgets, flame-graph analysis, and database query-plan analysis.
operations-resilienceVisual regression testing with Percy, Chromatic, Playwright screenshots and Storybook, plus chart rendering tests for Chart.js, D3 and Vega. Covers responsive breakpoint matrices, baseline conventions, and a binding baseline gate. Agents (visual-diff-classifier, visual-baseline-curator) sort diffs into intentional, incidental or regression and propose an initial baseline set.
quality-engineeringAgent skills for long-horizon work: turn goals into verified results, and lessons into better runs.
