Discover testing security testing skills, compare source repositories and read the instructions for each workflow.
Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behaviour, production pollution with test-only methods, and mocking without under...
Write, configure, and run unit + integration tests using project-independent best practices; detect tooling; triage failures/flakes; keep a compact Testing State Capsule.
Implement test-driven development (TDD) workflow using the red-green-refactor cycle. Use when writing new features, fixing bugs, or refactoring existing code. Always write the failing test first, then implement...
Automate browser testing, web scraping, and user workflow testing with Playwright across multiple browsers. Use when writing end-to-end tests for web applications, automating repetitive browser tasks, scraping...
Write comprehensive end-to-end tests that verify complete user workflows, integration between components, and system behavior from user perspective using Playwright, Cypress, or similar frameworks. Use when tes...
Validates discovered bugs with reproducing tests and validates fixes with regression tests. Called by other skills when bugs are found during optimization hunting. Creates property tests (proptest) and Kani pro...
Write tests following TDD principles. Use when implementing features, fixing bugs, or adding test coverage. Covers e2e, integration, and unit testing patterns.
Use when running claudikins-kernel:verify, checking implementation quality, deciding pass/fail verdicts, or enforcing cross-command gates — requires actual evidence of code working, not just passing tests
Use when testing PRPM CLI commands locally - provides build, environment setup, execution workflow, contract testing to verify documented behavior matches implementation, and comprehensive cross-format conversi...
Diagnose and fix tests that pass in isolation but fail when run concurrently. Covers shared state isolation and resource conflicts. References condition-based-waiting for timing issues.
Use to run pricing elasticity experiments with consistent assumptions and guardrails.
Use when establishing tests, monitoring, and incident response for analytics models.
Use when Playwright scripts fail, tests are flaky, selectors stop working, or timeouts occur - provides systematic debugging approach for browser automation issues
Use when writing or reviewing tests - covers test philosophy, condition-based waiting, mocking strategy, and test isolation
Use when writing Playwright automation code, building web scrapers, or creating E2E tests - provides best practices for selector strategies, waiting patterns, and robust automation that minimizes flakiness
Use when writing tests for serialization, validation, normalization, or pure functions - provides property catalog, pattern detection, and library reference for property-based testing
Use when creating new skills, editing existing skills, or verifying skills work before deployment - applies TDD to process documentation by testing with subagents before writing, iterating until bulletproof aga...
Orchestrates test planning pipeline (research → manual → auto tests). Coordinates ln-511, ln-512, ln-513. Invoked by ln-500-story-quality-gate.
Test suite audit coordinator (L2). Delegates to 5 workers (Business Logic, E2E, Value, Coverage, Isolation). Aggregates results, creates Linear task in Epic 0.
Test Isolation + Anti-Patterns audit worker (L3). Checks isolation (APIs/DB/FS/Time/Random/Network), determinism (flaky, order-dependent), and 6 anti-patterns.
Creates test documentation (testing-strategy.md + tests/README.md). Establishes testing philosophy and Story-Level Test Task Pattern. L2 Worker in ln-100-documents-pipeline workflow.
Worker that runs existing tests to catch regressions. Auto-detects framework, reports pass/fail. No status changes or task creation.
Plans automated tests (E2E/Integration/Unit) using Risk-Based Testing after manual testing. Calculates priorities, delegates to ln-301-task-creator. Worker for ln-510.
Performs manual testing of Story AC via executable bash scripts saved to tests/manual/. Creates reusable test suites per Story. Worker for ln-510.
