systematic-debugging

Root-cause-first debugging methodology for any bug, test failure, exception, or unexpected behavior — mandates investigation before proposing fixes. Use when something is broken, not working, crashing, or throwing errors; triggers: debug, error, bug, exception, stack trace, not working, crash.

browser-testing

Browser automation and testing using playwright-cli (stateful Bash CLI for scripted tests — network inspection, console monitoring, screenshots, tracing) and Browser-Use MCP (autonomous agent flows). Use when the user needs to test web apps, debug browser issues, analyze performance, fill forms, run E2E user flows, or inspect network/console activity.

decision-frameworks

Use when working through a specific problem or decision using a single reasoning framework applied deeply and interactively. Covers First Principles (break assumptions, rebuild from truth), Inversion (guarantee failure, then flip), Regret Minimization (decide from age 80), and Opportunity Cost (make tradeoffs visible). Triggers: "first principles", "inversion", "regret minimization", "opportunity cost", "help me think through", "challenge my assumptions", "what am I giving up", "work backwards from failure", "what would I regret".
