Security best practices and threat mitigation patterns for PACT framework development. Use when: implementing authentication or authorization, handling API credentials, integrating external APIs, processing sensitive data (PII, financial, health), reviewing code for vulnerabilities, or enforcing SACROSANCT security rules. Triggers on: security audit, credential handling, OWASP, auth flows, encryption, data protection, backend proxy pattern, frontend credential exposure.
Enable nullable reference types in a C# project and systematically resolve all warnings. USE FOR: adopting NRTs in existing codebases, file-by-file or project-wide migration, fixing CS8602/CS8618/CS86xx warnings, annotating APIs for nullability, cleaning up null-forgiving operators, upgrading dependencies with new nullable annotations. DO NOT USE FOR: projects already fully migrated with zero warnings (unless auditing suppressions), fixing a handful of nullable warnings in code that already has NRTs enabled, suppressing warnings without fixing them, C# 7.3 or earlier projects. INVOKES: Get-NullableReadiness.ps1 scanner script.

Use this skill to generate or audit design systems, check visual consistency, and review PRs that touch styling.
Detects anti-patterns and code smells in .NET test suites. Use when the user asks to review test quality, find test smells, identify flaky test indicators, or audit tests for common mistakes. Covers assertion quality, test isolation, naming, flakiness indicators, over-mocking, and structural problems. Works with MSTest, xUnit, NUnit, and TUnit.
When the user wants to create, optimize, or audit the API introduction/overview page. Also use when the user mentions "API page," "API landing page," "/api page," "API overview," "developer landing," "API marketing," or "API for developers." Note: API documentation (endpoint reference) lives in docs; use docs-page-generator.
Check and improve your brand's visibility across AI search engines (ChatGPT, Perplexity, Gemini, Grok, Claude, DeepSeek). Set up tracking, run visibility analyses, audit your website for AI readability, and get actionable recommendations. Uses the npx goose-aeo@latest CLI.
Security auditor for Claude Code skills and agent definitions. Scans a skill or agent directory for prompt injection, data exfiltration, privilege escalation, memory poisoning, obfuscation, malicious persistence, and 12 other threat categories (18 total). Returns a graded verdict (OK / WARNING / CRITICAL) with detailed findings. Use this skill whenever you need to audit, review, or validate the safety of a skill, an agent definition, a system prompt, or any set of instruction files before installing or trusting them. Also use it when the user mentions security scanning, threat detection, prompt injection checking, or wants to verify that a skill is safe. Triggers on: /maton, "audit this skill", "is this skill safe", "check for injection", "scan for threats", "review this agent", "security check".
Run an offline ASO audit on canonical App Store metadata under `./metadata` and surface keyword gaps using Astro MCP. Use after pulling metadata with `asc metadata pull`.
