Testing Craft CMS 5 plugins and modules with Pest — test isolation, database safety, and the markhuot/craft-pest-core harness. ALWAYS load when writing, running, fixing, or reviewing tests for a Craft plugin or module, and whenever a suite touches a real Craft install. Covers why rollback is opt-in, tests/Pest.php + tests/bootstrap.php wiring, phpunit.xml.dist <env> pins (force the DB name and table prefix, default the connection coordinates so CI still connects), why --configuration= defeats DB isolation, installing the plugin under test, pinning the process timezone after app creation, per-test site fixtures, idempotent Install migrations, stale service caches when components get swapped, muting audit sinks, queue stubs, factories, HTTP/DB assertions, CI test jobs. Triggers on: Pest, pestphp, craft-pest-core, markhuot, RefreshesDatabase, InstallsCraft, tests/Pest.php, phpunit.xml.dist, vendor/bin/pest, composer test, ddev craft pest, db_test, CRAFT_DB_DATABASE, CRAFT_DB_TABLE_PREFIX, Entry::factory(), assertDatabaseHas, afterEach, transaction rollback, test site fixture, fixture cleanup sweep, createIndexIfMissing, Db::findForeignKey, UserPermissions::reset(), 'too many keys', 'tests pollute the database', 'tests created thousands of entries', 'passes on dev but fails in isolation', 'passes alone but fails in the suite', 'datetimes off by hours in tests', 'connects locally but not on CI', flaky order-dependent test, no Pest job in CI. Do NOT trigger for front-end/JS testing or PHP style analysis.

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
Use when implementing any feature or bugfix, before writing implementation code
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
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
Expert guidance for systematic backtesting of trading strategies. Use when developing, testing, stress-testing, or validating quantitative trading strategies. Covers "beating ideas to death" methodology, parameter robustness testing, slippage modeling, bias prevention, and interpreting backtest results. Applicable when user asks about backtesting, strategy validation, robustness testing, avoiding overfitting, or systematic trading development.
Cloud laboratory platform for automated protein testing and validation. Use when designing proteins and needing experimental validation including binding assays, expression testing, thermostability measurements, enzyme activity assays, or protein sequence optimization. Also use for submitting experiments via API, tracking experiment status, downloading results, optimizing protein sequences for better expression using computational tools (NetSolP, SoluProt, SolubleMPNN, ESM), or managing protein design workflows with wet-lab validation.
This skill should be used for time series machine learning tasks including classification, regression, clustering, forecasting, anomaly detection, segmentation, and similarity search. Use when working with temporal data, sequential patterns, or time-indexed observations requiring specialized algorithms beyond standard ML approaches. Particularly suited for univariate and multivariate time series analysis with scikit-learn compatible APIs.
