Unit tests, integration tests, test automation
isolated-testing
by axiomantic
Use when testing theories during debugging, or when chaos is detected. Triggers: "let me try", "maybe if I", "what about", "quick test", "see if", rapid context switching, multiple changes without isolation. Enforces one-theory-one-test discipline. Invoked automatically by debugging, scientific-debugging, systematic-debugging before any experiment execution.
tdd
by jkitchin
Test-Driven Development facilitation using the red-green-refactor cycle. Guides users through writing tests first, implementing minimal code to pass, and refactoring for quality. Use when users want to practice TDD, need help writing tests before code, are developing new features test-first, or want guidance on test structure and implementation. Triggers include 'use TDD,' 'test-driven development,' 'write tests first,' 'red-green-refactor,' or requests to develop functionality with tests.
test-driven-development
by brobertsaz
Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first
idaes
by jkitchin
Comprehensive guidance for using IDAES (Institute for the Design of Advanced Energy Systems) for process systems engineering. Covers flowsheet modeling, property packages, unit models, optimization, scaling, initialization, and diagnostics. Use when working with chemical process simulations, energy systems modeling, power plant design, material and energy balances, or process optimization. Triggers include 'IDAES', 'flowsheet', 'process model', 'unit operation', 'process optimization', 'property package', 'energy systems', or process engineering tasks.
troubleshooting
by jkitchin
Systematic debugging and problem diagnosis using structured troubleshooting methodologies applicable to any domain - technical issues, process failures, system problems, or general obstacles. Use when users report errors, describe malfunctions, encounter unexpected behavior, or need help diagnosing root causes. Triggers include 'debug this,' 'troubleshoot,' 'why isn't this working,' 'getting an error,' 'something's wrong with,' 'how do I fix,' or any problem description.
