Advanced mutation testing using Stryker, PIT, and mutmut to measure test suite quality by introducing controlled mutations and tracking kill rates.
Advanced mutation testing using Stryker, PIT, and mutmut to measure test suite quality by introducing controlled mutations and tracking kill rates.
Test fixture design patterns including builders, factories, object mothers, and fixture management for maintainable test data setup.
Testing distributed tracing implementations including context propagation, span correlation, baggage handling, and trace sampling verification.
Create and manage a SOC 2 risk register — auto-seeds from scan findings, tracks treatment, produces audit evidence.
Guide to quantitative Western blot analysis covering band detection, two-step normalization, fold change calculation, statistical aggregation across biological replicates, and publication-ready visualization. Consult when analyzing blot images with multiple conditions and repetitions, choosing normalization strategies, or preparing densitometry figures for publication.
Aggregate and analyze IoT sensor data from construction sites. Collect data from multiple sensor types, detect anomalies, and trigger alerts for safety and quality monitoring.
Monitor environmental conditions on construction sites. Track air quality, noise levels, vibration, dust, and weather to ensure compliance and worker safety.
Run or continue a differential debugging session between two implementations, traces, captures, or outputs. Record artifact identity, exact commands, first mismatch progression, findings, validation, and next probe in a durable session log.
Safe testing practices to prevent real-world side-effects. TRIGGER when user asks to "run tests", "test this", "write tests", "debug", "mock", "fixture", "integration test", "unit test", or when testing code that touches network, database, filesystem, or external services. Use BEFORE executing any test that could affect production systems.
Reconcile GL balances to subledger, bank, or third-party balances
Generate SOX sample selections, testing workpapers, and control assessments
Captures human source verification for tracks, timestamps it, and updates track files. Use when sources need human review before generation.
Catalog existing tests — discover test frameworks, count tests by type, parse coverage reports, and map test-to-feature relationships. Pure discovery — no gap analysis, no recommendations for new tests, no assessment of test quality. Use when you need a factual inventory of the testing landscape before migration or modernization planning.
ISO 13485 internal audit expertise for medical device QMS. Covers audit planning, execution, nonconformity classification, and CAPA verification. Use for internal audit planning, audit execution, finding classification, external audit preparation, or audit program management.
CAPA system management for medical device QMS. Covers root cause analysis, corrective action planning, effectiveness verification, and CAPA metrics. Use for CAPA investigations, 5-Why analysis, fishbone diagrams, root cause determination, corrective action tracking, effectiveness verification, or CAPA program optimization.
This skill should be used when the user asks to "set up an A/B test", "calculate sample size", "design an experiment", "analyze A/B test results", "check statistical significance", "determine test duration", or "evaluate conversion rate experiments".
EU MDR 2017/745 compliance specialist for medical device classification, technical documentation, clinical evidence, and post-market surveillance. Covers Annex VIII classification rules, Annex II/III technical files, Annex XIV clinical evaluation, and EUDAMED integration.
