Skill UI

Expert in developing complete, high-performance firmware and peripheral drivers for ARM Cortex-M platforms (STM32, Teensy, nRF52). Specializes in low-level hardware interaction, including implementing drivers for I²C, SPI, UART, and managing complex concurrency patterns using FreeRTOS/Zephyr. Provides critical guidance on optimizing for determinism, cache coherency, DMA transfers, and memory barriers to ensure reliable embedded system operation.

A comprehensive guide for establishing robust, enterprise-grade access control within Databricks. Covers implementing Single Sign-On (SSO) via SCIM, leveraging Unity Catalog for fine-grained Role-Based Access Control (RBAC), defining cluster policies, and enforcing data governance measures like Row-Level Security (RLS) and column masking. Essential for large-scale, secure data platforms.

This skill provides expert-level diagnostic capabilities for complex distributed systems. It specializes in analyzing production incidents, identifying deep root causes, and designing comprehensive observability solutions. Use this when investigating recurring errors, reviewing system logs/traces, and implementing preventative reliability measures.

A comprehensive guide detailing the entire workflow for analyzing embedded firmware. It covers hardware-level extraction methods (UART, JTAG, SPI dump), filesystem analysis (SquashFS, JFFS2), binary reverse engineering using tools like Ghidra, and identifying common vulnerabilities (Buffer Overflow, Command Injection). Ideal for security researchers and embedded systems engineers.

This skill specializes in implementing Service Level Objectives (SLOs) and Service Level Indicators (SLIs) to enforce reliability standards. It guides users in designing comprehensive SLO frameworks, calculating error budgets, and building robust monitoring systems. Use this when you need to establish data-driven reliability targets, balance feature velocity with technical health, and align service performance directly with core business objectives.

This skill provides comprehensive expertise for senior database administrators to optimize and manage PostgreSQL databases at an advanced level. Use it for deep query analysis via EXPLAIN ANALYZE, implementing advanced features like JSONB indexing, configuring streaming or logical replication, and maintaining database health through VACUUM tuning and monitoring pg_stat views. Ideal for building highly available, high-performance, and resilient system architectures.

This skill provides a comprehensive suite for executing load testing, stress testing, and performance benchmarking. Use it to simulate peak traffic, identify system bottlenecks, and verify compliance with Service Level Agreements (SLAs). It supports industry-standard tools like k6, Artillery, Locust, and JMeter for robust performance analysis.

This comprehensive checklist guides the secure deployment and hardening of a Supabase project for production use. It covers critical security measures such as enforcing Row Level Security (RLS), separating client and service keys, optimizing connection pooling via Supavisor, setting up Point-in-Time Recovery (PITR) backups, and configuring network restrictions. Use this guide before launching or for conducting security audits to ensure maximum stability and security.

Guides designing IEC 62443-3-2 compliant OT security zones and conduits, covering risk-based partitioning, Security Level targets, conduit controls, microsegmentation with industrial firewalls, and validating the zone architecture through traffic analysis and testing.

This guide details advanced techniques used in red teaming and penetration testing to elevate user privileges from a low-level account to root access on a compromised Linux system. It covers exploiting misconfigurations, vulnerable services (like SUID/SGID binaries), improper sudo rules, kernel vulnerabilities (e.g., Dirty Pipe), and abuse of system services like Cron jobs and Systemd. Essential for authorized security assessments.

Provides comprehensive, enterprise-level monitoring for all Power Automate flows across an entire tenant. Using a cached store, it tracks failure rates, run health trends, asset inventory (makers, apps, connections), and compliance reports without hitting API rate limits. Ideal for governance teams needing an aggregated view of platform health and root-cause analysis.

A comprehensive guide to implementing Role-Based Access Control (RBAC) in ClickHouse. Learn how to manage user authentication, define hierarchical roles, enforce row-level security (RLS) for tenant isolation, restrict data access via column-level grants, and manage resource consumption using quotas and settings profiles. Essential for multi-tenant SaaS and secure data analytics platforms.
