Convert between XNO units (raw/xno/knano/mnano) with exact BigInt precision.
Vector embeddings with HNSW indexing, sql.js persistence, and hyperbolic support. 75x faster with agentic-flow integration. Use when: semantic search, pattern matching, similarity queries, knowledge retrieval. Skip when: exact text matching, simple lookups, no semantic understanding needed.
Look up phone number information (carrier, type, caller name) and verify users via SMS/voice OTP. Use for phone verification and data enrichment. This skill provides Go SDK examples.
Review and implement safe concurrency patterns in Go: goroutines, channels, sync primitives, context propagation, and goroutine lifecycle management. Use when writing concurrent code, reviewing async patterns, checking thread safety, debugging race conditions, or designing producer/consumer pipelines. Trigger examples: "check thread safety", "review goroutines", "race condition", "channel patterns", "sync.Mutex", "context cancellation", "goroutine leak". Do NOT use for general code style (use go-coding-standards) or HTTP handler patterns (use go-api-design).
Deep dive on table-driven tests in Go: when to use them, when to avoid them, struct design, subtest naming, advanced patterns like test matrices and shared setup, and refactoring bloated tables into clean ones. Use when writing table-driven tests, refactoring test tables, reviewing table test structure, or deciding whether table-driven is the right approach. Trigger examples: "table-driven test", "table test", "test cases struct", "test matrix", "parametrize tests", "data-driven test", "refactor test table". Do NOT use for general test strategy, mocking, golden files, or fuzz testing (use go-test-quality). Do NOT use for benchmarks (use go-performance-review).
Review Go project architecture: package structure, dependency direction, layering, separation of concerns, domain modeling, and module boundaries. Use when reviewing architecture, designing package layout, evaluating dependency graphs, or refactoring monoliths into modules. Trigger examples: "review architecture", "package structure", "project layout", "dependency direction", "clean architecture Go", "module boundaries". Do NOT use for code-level style (use go-coding-standards) or API endpoint design (use go-api-design).
Detect performance anti-patterns and apply optimization techniques in Go. Covers allocations, string handling, slice/map preallocation, sync.Pool, benchmarking, and profiling with pprof. Use when checking performance, finding slow code, reducing allocations, profiling, or reviewing hot paths. Trigger examples: "check performance", "find slow code", "reduce allocations", "benchmark this", "profile", "optimize Go code". Do NOT use for concurrency correctness (use go-concurrency-review) or general code style (use go-coding-standards).
Security review for Go applications: input validation, SQL injection, authentication/authorization, secrets management, TLS, OWASP Top 10, and secure coding patterns. Use when performing security reviews, checking for vulnerabilities, hardening Go services, or reviewing auth implementations. Trigger examples: "security review", "check vulnerabilities", "OWASP", "SQL injection", "input validation", "secrets management", "auth review". Do NOT use for dependency CVE scanning (use go-dependency-audit) or concurrency safety (use go-concurrency-review).
Comprehensive guide for implementing the Syncfusion React Calendar component with quick navigation, when-to-use guidance, and reference links for common tasks. Use this skill for copy-paste-ready examples and decision guidance for date selection UI in React applications.
Use when the user needs prompt design, optimization, few-shot examples, chain-of-thought patterns, structured output, evaluation metrics, or prompt versioning. Triggers: new prompt creation, prompt optimization, few-shot example design, structured output specification, A/B testing prompts, evaluation framework setup.
Guide for implementing Syncfusion WinForms NumericUpDownExt control in Windows Forms applications. Use when users need enhanced numeric input with XP themes, value constraints (min/max/increment), hexadecimal display, decimal places, thousands separator, or themed borders beyond standard WinForms NumericUpDown.
25+ proven headline formulas that stop the scroll, capture attention, and drive clicks. Templates and examples for every situation. Use when: Writing headlines for landing pages, ads, or articles; Creating email subject lines that get opens; Crafting social media hooks; A/B testing headline variations; Overcoming headline writer's block
