Use when choosing the best first failing RSpec spec or vertical slice for a Ruby on Rails change. Covers request vs model vs service vs job vs engine spec selection, system spec escalation, smallest safe slice planning, and Rails-first TDD sequencing. Trigger words: where to start testing, what test to write first, RSpec, test-driven development, TDD, first failing test.
Embedded network debugging tool used for interface discovery, packet capture, pcap/pcapng analysis, connectivity testing, port scanning, and traffic statistics. It is automatically triggered when users mention network protocol debugging terms such as Wireshark, tshark, Npcap, packet capture, network joint debugging, port scanning, connectivity troubleshooting, pcap analysis, network interface, ping test, traceroute, traffic statistics, Modbus TCP, EtherNet/IP, etc. It also supports explicit invocation via /net. Even if users only say "capture a packet", "scan ports", "check network connectivity" or "analyze this pcap", this skill should be triggered as long as the context involves network communication debugging.
Research methodologies, user interviews, surveys, usability testing, persona creation, and insight extraction
Identifies and exploits SQL injection vulnerabilities in web applications during authorized penetration tests using manual techniques and automated tools like sqlmap. The tester detects injection points through error-based, union-based, blind boolean, and time-based blind techniques across all major database engines (MySQL, PostgreSQL, MSSQL, Oracle) to demonstrate data extraction, authentication bypass, and potential remote code execution. Activates for requests involving SQL injection testing, SQLi exploitation, database security assessment, or injection vulnerability verification.
Leadpages platform help — landing page builder, pop-ups, alert bars, A/B testing, lead enrichment, Stripe payments, AI content, Leadmeter conversion scoring. Use when building a landing page in Leadpages, Leadpages template isn't converting, A/B test setup in Leadpages, connecting Leadpages to email or CRM, pop-up or alert bar not showing, Leadpages page is slow to load, or choosing between Leadpages Standard vs Pro plan. Do NOT use for general funnel strategy (use /sales-funnel) or email marketing sequences (use /sales-email-marketing).
Automated browser testing with Playwright -- navigate, interact, screenshot, and validate UI
Evaluates ML models for performance, fairness, and reliability. Use for metric selection, cross-validation strategies, overfitting/underfitting diagnosis, hyperparameter tuning, LLM evaluation, A/B testing, and production monitoring for model drift.
Set up Playwright end-to-end testing in a project, including test configuration, example tests, and CI integration.
Generates Codeception tests in PHP covering acceptance, functional, and unit testing. BDD-style with Actor pattern. Use when user mentions "Codeception", "$I->amOnPage", "$I->see", "Cest". Triggers on: "Codeception", "$I->amOnPage", "AcceptanceTester", "Codeception PHP", "Cest".
Guides security assessment of embedded and cyber-physical systems on hardware-in-the-loop (HIL) test benches—bench setup, ECU/ECM or PLC targets, bus interfaces (CAN/CAN-FD, LIN, automotive Ethernet, Modbus at high level), fault injection and stimulus design, simulated plant/environment integration, attack-surface monitoring on real hardware, reproducible test cases, lab safety interlocks, and evidence capture for firmware and vehicle security teams. Use for HIL security testing, ECU security assessment, CAN bus security, PLC HIL test, fault injection lab, embedded hardware security—not web/API pentest (web-pentester), network-only pentest (network-pentester), malware/binary RE only (reverse-engineer), SOC operations (soc-analyst), AI red team (ai-redteam), classified ISSO paperwork (information-systems-security-officer-classified-specialist), or pure software CI without hardware (build-validator).
Soroban smart contract development on Stellar (Rust SDK). Covers project setup, contract structure, storage types, authorization, cross-contract calls, events, error handling, testing (unit, integration, fuzz, property, mutation, fork, differential), security patterns and vulnerability classes, advanced architecture patterns (upgrades, factories, governance, DeFi primitives), and common pitfalls. Use when writing, testing, securing, or shipping Soroban contracts.
Performance review and testing: evaluate Core Web Vitals, page load times, bundle sizes, runtime performance, resource optimization, and rendering efficiency with browser-based measurement and benchmarking.
