> with-custom-agent

Use when testing custom agent validation

> axiom-in-app-purchases

Use when implementing in-app purchases, StoreKit 2, subscriptions, or transaction handling - testing-first workflow with .storekit configuration, StoreManager architecture, transaction verification, subscription management, and restore purchases for consumables, non-consumables, and auto-renewable subscriptions

> brainstorm-experiments-existing

Design experiments to test assumptions for an existing product — prototypes, A/B tests, spikes, and other low-effort validation methods. Use when validating assumptions, testing feature ideas cheaply, or planning product experiments.

> axiom-database-migration

Use when adding/modifying database columns, encountering "FOREIGN KEY constraint failed", "no such column", "cannot add NOT NULL column" errors, or creating schema migrations for SQLite/GRDB/SQLiteData - prevents data loss with safe migration patterns and testing workflows for iOS/macOS apps

> vue-testing-best-practices

Use for Vue.js testing. Covers Vitest, Vue Test Utils, component testing, mocking, testing patterns, and Playwright for E2E testing.

> wordpress-router

Use when the user asks about WordPress codebases (plugins, themes, block themes, Gutenberg blocks, WP core checkouts) and you need to quickly classify the repo and route to the correct workflow/skill (blocks, theme.json, REST API, WP-CLI, performance, security, testing, release packaging).

> managing-database-recovery

This skill manages database recovery operations using the database-recovery-manager plugin. It enables disaster recovery, point-in-time recovery (PITR), and automated failover strategies for production database systems. Use this skill when the user requests help with "database recovery", "disaster recovery", "point-in-time recovery", "PITR", "backup validation", "recovery testing", or "multi-region failover" for databases. It automates backup verification and recovery testing.

> common-skill-creator

Standards for creating, testing, and optimizing Agent Skills for any AI Agent (Claude, Cursor, Windsurf, Copilot). Use when: writing SKILL.md, auditing a skill, improving trigger accuracy, checking size limits, structuring references/, writing anti-patterns, starting a new skill from scratch, or reviewing skill quality.

> axiom-testing-async

Use when testing async code with Swift Testing. Covers confirmation for callbacks, @MainActor tests, async/await patterns, timeout control, XCTest migration, parallel test execution.

> automation-workflows

Design and implement automation workflows to save time and scale operations as a solopreneur. Use when identifying repetitive tasks to automate, building workflows across tools, setting up triggers and actions, or optimizing existing automations. Covers automation opportunity identification, workflow design, tool selection (Zapier, Make, n8n), testing, and maintenance. Trigger on "automate", "automation", "workflow automation", "save time", "reduce manual work", "automate my business", "no-code

> php-testing

Write unit and integration tests for PHP applications with PHPUnit and Pest. Use when writing PHPUnit unit tests or integration tests for PHP applications. (triggers: tests/**/*.php, phpunit.xml, phpunit, pest, mock, assert, tdd)

> axiom-swiftdata-migration

Use when creating SwiftData custom schema migrations with VersionedSchema and SchemaMigrationPlan - property type changes, relationship preservation (one-to-many, many-to-many), the willMigrate/didMigrate limitation, two-stage migration patterns, and testing migrations on real devices

> axiom-swiftdata-migration-diag

Use when SwiftData migrations crash, fail to preserve relationships, lose data, or work in simulator but fail on device - systematic diagnostics for schema version mismatches, relationship errors, and migration testing gaps

> code-auditor

Performs comprehensive codebase analysis covering architecture, code quality, security, performance, testing, and maintainability. Use when user wants to audit code quality, identify technical debt, find security issues, assess test coverage, or get a codebase health check.

> swift-testing

Write XCTest cases, async tests, and organized test suites in Swift. Use when writing XCTest cases, async tests, or organizing test suites in Swift. (triggers: **/*Tests.swift, XCTestCase, XCTestExpectation, XCTAssert)

> axiom-background-processing

Use when implementing BGTaskScheduler, debugging background tasks that never run, understanding why tasks terminate early, or testing background execution - systematic task lifecycle management with proper registration, expiration handling, and Swift 6 cancellation patterns

> axiom-core-data-diag

Use when debugging schema migration crashes, concurrency thread-confinement errors, N+1 query performance, SwiftData to Core Data bridging, or testing migrations without data loss - systematic Core Data diagnostics with safety-first migration patterns

> Broken Authentication Testing

This skill should be used when the user asks to "test for broken authentication vulnerabilities", "assess session management security", "perform credential stuffing tests", "evaluate password policies", "test for session fixation", or "identify authentication bypass flaws". It provides comprehensive techniques for identifying authentication and session management weaknesses in web applications.

> dummy-dataset

Generate realistic dummy datasets for testing with customizable columns, constraints, and output formats (CSV, JSON, SQL, Python script). Use when creating test data, building mock datasets, or generating sample data for development and demos.

> identify-assumptions-existing

Identify risky assumptions for a feature idea in an existing product across Value, Usability, Viability, and Feasibility. Uses multi-perspective devil's advocate thinking. Use when stress-testing a feature idea, doing risk assessment, or preparing for assumption mapping.
